Thin provisioning?

Hi All,
I am working on a deployment project Exchange 2013, We have planned to deploy exchange 2013 on VMware platform. Could some one share your experience Exchange 2013 with VMware . I have already gone trough the VMware recommendations but i am looking for some
one with practical experience that would be really help full for me to accomplish this task successfully. 
First Question : Can we use thin provisioning for Database and logs?
Second Question : what type of disk we need to use for DB & Logs (RDM or VMFS)? I am beginner to vmware sorry if i have asked any wrong question here :-)
Third Question : How to Size the processor for exchange 2013 with MSCalc? I have followed the below article for MScalc still have some doubts on Processor calculation. :-)
http://blogs.technet.com/b/exchange/archive/2009/11/09/3408737.aspx 
Here is the server details, could some one help me with the Processor part, I appreciate your response.
Phycial 4 sockets, 32 cores in total, 256 GB of RAM
SPECint®_rate2006 = 1130
Regards, Balgates

Hi Balgates,
In addition to the above suggestions, I would like to clarify that the megacycle guidance in Exchange 2013 leverages a new server baseline, therefore, you can't directly compare the output from the Exchange 2010 calculator with Exchange 2013 calculator.
For more information about it, here is a blog for your reference.

  • ISCSI and ZFS Thin Provisioning Sparse Volumes - constraints?

    Hello,
    I am running an iSCSI target using COMSTAR.
    I activated Time Slider (Snapshot feature) for all pools.
    Now I want to set up an iSCSI target using thin provisioning, storing the data in a file system rather than a file.
    Is there any official documentation about thin p.?
    All I found was
    http://www.cuddletech.com/blog/pivot/entry.php?id=729
    http://www.c0t0d0s0.org/archives/4222-Less-known-Solaris-Features-iSCSI-Part-4-Alternative-backing-stores.html
    Are there any problems to be expected about the snapshots?
    How would I set up a 100 GByte iSCSI target with mentioned thin p.?
    Thanks
    n00b

    To create a thin provisioned volume:
    zfs create -V <SIZE> -s path/to/volume
    Where <SIZE> is the capacity of the volume and path/to/volume is the ZFS path and volume name.
    To create a COMSTAR target:
    stmfadm create-lu /dev/zvol/rdsk/path/to/volume
    You'll get a LU ID, which you can then use to create a view, optionally with target and host groups to limit access.

  • ASM Volumes on thin-provisioned ISCSI dirtying whole volumes

    Hi, we've got some EBS test instances going and are testing auto-extend (in reasonable chunks) on a thin-provisioned ISCSI volume for the 11g database tier. Something doesn't seem right though: typically I see about 55GB in use by datafiles but about 95% of the thin-provisioned volume is marked dirty.
    Obviously, this sort of negates the point of using thin provisioning at all, but I can't help but think there's something else at work here. Does anyone have experience with this situation and if so what parameters can be set to make what we're trying to do actually work right?

    Billy, thank you for the helpful reply. In this case, none of that is news to me - we wear a lot of hats where I work and in this case I not only put together the systems the ASM instance is running on, but the ASM instance itself (DB is at 11.1.0.7 with the 6851110 ASM patch recently applied). System is OEL 5 x86_64, the ISCSI volume is thin-provisioned, no filesystem ever written to it, raw disk other than a partition table, holds DATA and FRA, configured with autoextend on.
    What I'm trying to get at here is why a 500GB volume which is holding only about 55GB of data would have almost all its blocks marked dirty - as far as the filer is concerned, something has touched nearly every block on the volume at one point or another. Now if I'd written a 500GB datafile to it - which as you say is pointless where ASM is concerned - I'd understand how the blocks got dirtied, but in this case that never happened - it's somewhere in the way ASM behaves (as far as I can see now anyway) that has caused the data to be written all over the physical blocks on the drive, even if only momentarily.
    So getting back to my original question, is there a way in ASM to ensure that writes are done in a contiguous fashion so that the apparent disk usage (from the SAN point of view) more closely matches the actual amount of data stored? I'm not seeking a 1:1 relationship here, but we're close to 1:10, and I think that's only because that's how big I sized the volume in the first place. As far as it being ISCSI, the only relevance (and the whole point of my question) is that it's how I happened to attach the volume, which was intended to be thin-provisioned and only allocate space when it's needed. If I'd made the volume 250GB (and I can test this theory if need be), it would likely dirty 250GB of blocks and still store the same 55GB of data. My hope is that there's a way to get ASM to play nicer on thin-provisoned volumes than what I'm currently seeing.
    Thanks again.

  • ASM Volumes on thin-provisioned SAN dirtying all blocks

    Hi there, sorry for the x-post from database-general but it was suggested that I do so. Anyhow, we've got 11g (11.1.0.7 with the 6851110 ASM patch recently applied) running on OEL 5 x86_64, with ASM connected to a raw, thin-provisioned ISCSI volume partitioned for DATA and FRA, and in every case where we do so, the SAN device reports within a few weeks that the whole volume has been allocated even though the DB (configured with autoextend on) is only holding about one tenth of the amount of available space on the device. What this means in systems terms is that somehow ASM is marking writes to nearly every block on the drive if only momentarily.
    In the original thread, there was speculation that a process of indexing AUs has led to the dirtying of the whole volume, but this would make more sense if the whole disk had been allocated immediately rather than over the course of a few weeks. My question is: what else could account for this behavior, and what steps can I take to help ensure that ASM behaves correctly in a thin-provisioned volume? (by "correctly" I mean writes contiguous blocks of data and doesn't dirty the whole thing)
    Thanks!

    Hi,
    recently i had some time and did some tests with thin provisioning and ASM.
    I used storage based on Opensolaris with ZFS thin provisioning against a 11g R2 database with 11g R2 ASM running on Windows. I created two LUNs and exported the LUNs via iSCSI. On the ASM side i formed a single disk group with external redundancy of the two LUNs presented and created one big file tablespace with approx 15 GB total size.
    The storage systems shows the LUNs as follows:
    NAME                       PROPERTY       VALUE    SOURCE
    pool1/iscsi-racwin-temp05  volsize        15G      local
    pool1/iscsi-racwin-temp05  usedbydataset  7.45G    -
    pool1/iscsi-racwin-temp06  volsize        15G      local
    pool1/iscsi-racwin-temp06  usedbydataset  7.45G    -You can see: 15 GB total size reported while 7.45 GB are allocated. Thats pretty normal due to the data file created in the disk group.
    During the night i ran a script which imported a schema and dropped it afterwards. The steps were repeated infinitely.
    After more than 24 hours the thin provisioned disks look like this:
    NAME                       PROPERTY       VALUE    SOURCE
    pool1/iscsi-racwin-temp05  volsize        15G      local
    pool1/iscsi-racwin-temp05  usedbydataset  7.47G    -
    pool1/iscsi-racwin-temp06  volsize        15G      local
    pool1/iscsi-racwin-temp06  usedbydataset  7.47G    -As you can see there is a extremely small growth in size (from 7.45 GB to 7.47 GB). I observed this growth shortly after starting the very first import. Subsequent imports did not increased the actual allocated volume size.
    So if we exclude the storage as a source for problems there might be the fact that 11g R1 ASM behaves different than 11g R2 ASM. I have not yet tested this...

  • Whether Hyper-V 2012 will support Thin provisioning ?

    Hi All,
           I am installing windows server 2012 in Hyper V as a VM using iso images.... While creating new virtual machine in Hyper-V I am not able to see any options like "Thin Provisioning"... In Hyper V how thin provisioning will
    work and how to enable it?
    I install one Server 2012 in Hyper V--> It display harddisk type as "xxxx.vhdx"
    Note:In Vmware the thin provisioning option is available while creating virtual machines.
    Thanks,
    Rajarajan.D

    Hello,
    I hope you have a great day.
    Creating the VHDX file as dynamically expanding, is the VMware equivalent to thin provisioning.
    Example: Create dynamically vhdx with size of 100 GB and install Server 2012 OS. The Guest OS will see drive capacity as 100GB however the actual vhdx file would only consume about 15 - 30GB physical hard disk space depending on the features/roles you
    install in the OS.
    Creating a 100GB Fixed VHDX would consume 100GB of physical hard disk space.

  • Do I need to extend the OS disk if my Datastore is thin provisioned?

    I noticed on my windows server (VM) that one of the disk drives was getting low. This was showing 22gb free from the OS. (Windows 2008 R2)  It is functioning as the file storage and print server.   So, I extended the SAN LUN by 100gb, extended the vCenter Datastore by the same amount and now it's showing in vCenter that I have an extra 100gb of space. On the OS, it's still showing 22gb free.  I know that if I go into the VM and edit the properties of the disk drive, and add up to 100gb of space, then on the OS, in this case Windows I can go into disk management and extend the volume I will see the additional space.  My question, Do I need to do this if my Datastore is thin provisioned? Will it not grow if needed?  or am I getting the OS and VMware confused as to how it functions?

    You will need increase the size of virtual disk on the properties of virtual machine to the desired size and after this, if Windows, go to disk management (or diskpart) and extend the disk.
    And about the thin provisioning concept, you're confused and I recommend you read this article: Using thin provisioned disks with virtual machines (1005418)

  • New install of Horizon 6.1. It's normal that provisioning linked-clones will take a long time ?

    Hi,
    First, I will describe my installation :
    1 Management Server : Dell PowerEdge R730 48 cores, 2.5 Ghz with 9 HDD 300 GB SAS 15K (RAID 5) and 256 Gb RAM
    2 VDI Hosts server : Dell PowerEdge R730 48 cores, 2.5 Ghz with 9 HDD 300 GB SAS 15K (RAID 5) + 1 SSD 200 GB, 256 Gb RAM, 2 grid K1 cards
    1 LUN on an Dell Equallogic PS6110X (750 GB) where I put the masters.
    1 switch Dell N4032F (10 Gb)
    All server will have 4 ports 10Gb configured with NPAR (so, i have 6 x 10 Gb virtual nic for the storage and 6 virtual nic for the VM network) and 2 ports 1 Gb for the management.
    My master :  Windows 7 SP1 x86 optimized with 24 Go HDD Thin-Provisionned (2 vCPU, 2 Go RAM, VMXNET 3 network cards). There is none added application on this master.
    I can't apply the Microsoft patch for VMXNET 3 because it says that this patch is not applicable.
    I don't have VSAN because only 2 VDI hosts, so I configure my pool for each hosts with local storage for the linked clones and local SSD for the replica.
    When I run the provisionning of the desktop pool (17 VM):
    The clone of the replica (Equallogic ==> local SSD) will take 2'30".... That's good for me (113 MB/s... the Equallogic is also used for another server storage on other LUN)
    But the rest of all operation to finish the provisionning will take 40'.
    More than 50% of cores will mount to 100% CPU on the host.
    I have tried to change my RAID5 (9 hard disk + 1 spare) to RAID10 (10 HDD). It take 50'.
    And, when all operations are finished... I have 2 or 3 VM with the message : Agent Unreachable and 1 or 2 hangs on Provisionning.
    A recompose a one VM Desktop will take approximatively 1'30.
    My question : it's normal that the provisioning will take so much time ?
    And other question : when i'm connected to a VM Desktop with Horizon client during a pool provisioning, the VM freeze or i simply can't connect. Even if i have ready desktop. And sometimes, vCenter client will freeze to a lot of seconds during provisioning
    Have someone idea ?
    PS : Sorry for my approximate English ;-)

    Today, i have try to put the RAID in RAID 0.
    Result : always 50 minutes for provisioning.
    So, the problem is not the RAID...
    In vRealize Operation Manager, I see that i have latency in disk command and disk operation (up to 7000 ms !!!!).
    And in vCenter performance (all type of performance), I have a lot of blank graphics during 5 to 20 seconds in different steps.
    I don't know where were looking my problem...
    Any idea ?

  • V2V to reduce provisioned size of VM while powered-on: How? vCenter 5.5

    Unfortunately, VMware Converter does not allow you to do post-conversion synchronizations when shrinking a disk, only when maintaining or increasing the size. This means you would lose all changes that happen after the conversion starts. The only supported way to do this with the VM turned on is using Storage vMotion, if you have that feature.
    The sdelete process is actually quite safe when done correctly, but the second part of the process -- removing zeroed blocks from the VMDK -- does require the VM to be turned off when it runs.

    So, I have a VM that's grown unnecessarily large and I need to shrink the provisioned size, but I rarely have a chance to power it off. Is it possible to do a V2V with VMware Converter while the VM is powered on and running? The VMDK of the VM in question is Thin-Provisioned currently. I have read this can be done with SDelete, but that is a dangerous route. This a production machine that we heavily rely on, so I need to go the safest route possible. Thank you....

  • Space reclaimer on Thick Provisioned LUN

    Hi, Could someone clarify something for me. I understand the need to reclaim space on thin provisioned LUNs using SnapDrive's space reclaimer. Is this a requirement for thick provisioned LUNs or will running it only fix the space reporting in System Manager. As an example - a 10Tb thick provisoned LUN is presented to a physical Windows server and mapped to a drive. 6tb of data is written to the LUN, and Windows and System Manager both agree that there is 4Tb free. All of the data is deleted. Windows sees 10Tb free and System Manager still sees 4Tb free as it has no way of knowing the blocks have been marked as deleted. Expected behaviour. Now if we write another 6Tb to the volume will there be space? The LUN will eventualy show 100% full, but after this will Windows quite happily carry on writing to the drive? I could test this but I wondered if anyone had any real world experience. In my organisation we have a process regularly run Snapdrive space reclaimer on thick provisioned LUNs and I am wondering if we need to (other than getting system manager to report correctly)? Many Thanks, Jason

    It's still complicated I do not really know what combination of settings System Manager is using for "thick provisioned"; if we speak about space gurantee == volume and fractional reserve == 100% then you should always have enough space to (over-)write full LUN size.But note that under some conditions NetApp may not honor volume space gurantee ...

  • PI and MSE VMware disk provisioning

    Hello,
    Can someone tell me if it's permitted to thin provisioning teh VMware appliance for both PI and MSE?
    Tank you

    I have in a lab, but will not deploy it that way in production. I even have it thick provisioned in my home lab. Remember that TAC will only support thick provisioning since that is how they configure the ova.

  • Moving Thin Template w/ Linked Clones

    We've got 6 Gold Thin Provisioned Templates and have filled the datastore they are on. Long story how this happened. The process that is used is a user Clones to Workspace using a Linked clone and then deploys the machine from there.
    I need to spread these thin provisioned templates out across other datastores so this doesnt happen in the future but my understanding is that if I use the Consolidate action to move one of these templates this will effect all of the linked clones. Is this correct?
    If so is there any other way to move a Thin Template to a new datastore and not break the linked clones?
    The only other option is making a copy\clone of the template and moving it but the problem so far with that is this converts the template from Thin to Thick as we are using LM 4.0.2. So if I Cloned the template and it converted to Thick is there a way to get it back to Thin again?
    Then I could take those new Thin Templates and spread them out and those could be used as the old ones get undeployed.
    Thanks for reading this far and any suggestions.

    Option 1: Move an existing Template and all related VMs:
    SSMove will relocate (cut/paste) an entire linked clone tree between datastores.  However, I would want you to be on Lab Manager 4.0.4 (final version) as there are some minor improvements to the tool.
    You also need to undeploy all the related VMs to do this.
    Option 2: move the template only via a full consolidate.
    This move the template only.  The template gets consolidated to the new datastore.  Any new VMs provisioned from the template will go to the new datastore where the vmdk resides.
    The previous VMs will still exist and function.  As they are deleted, space will be freed on the previous drive.  If all related VMDKs to the orignial tree are deleted, then the entire tree will be cleaned up.

  • [S]Systemd can't start Load Kernel Modules after upgrade to Linux 4.0

    After upgrading from linux 3.19.3-3 to 4.0.1-1 I've been having a bit of an issue. At that same time I upgraded readline (6.3.006-1 → 6.3.008-1), linux-firmware (20150206.17657c3-1 → 20150410.ec89525-1), nvidia (349.16-1 → 349.16-2) , wpa_suplican (2.4-1 → 1:2.3-1), and  arpack (3.1.5-1 → 3.2.0-1). There may be some typos there since I'm copying by hand. Normally this wouldn't be much of a problem because I have been, priory to a few weeks ago, really good about back ups and would just roll my OS back 15 minutes. But things like that tend to fly out the window when the semester gets heavy. My last snapshot was on May 22nd, which I could still use, but would rather not. Also, it seems like a good idea to try to actual fix things for a change.
    [edit] I should mention that this upgrade was run April 30th.[/edit]
    When I finished booting the system after the upgrade, I got an error message during boot “systemd[1]: Failed to start Load Kernel Modules.” When it finished booting I run “dmesg -l err” to confirm that I'm not having a bad day dream or something. I'm also still seeing the errors that I described in this thread. Don't know if the two are related. I also noticed, when I was logging in, that it said that my stystem was still using the old kernel. Indeed, according to “uname -r” I'm still using 3.19.3-3-ARCH.
    The closest thing to experience I have with this is when I forget to mount /boot before upgrading linux, so I made sure /boot was mounted and rand “sudo pacman -S linux” to reinstall, but this didn't help. Just to check I ran “ls /lib/modules” and see the directorys “4.0.1-1-ARCH” and “extramodules-4.0-ARCH” as I would expect after a succesful upgrade of the kernel.
    Running “systemctl –failed, shows that in addition to systemd-modules-load.service, lm_sensors.service has also failed. I somehow expect lm_sensors depends on systemd-modules-load. I tried “systemctl restart systemd-modules-load”, but was rewarded with a message telling me that it failed. The “journalctl -xe” log has the lines
    systemd[1]: system-modules-load[1799]: Failed to look up alias 'sg': Function not implemented
    systemd[1]: system-modules-load[1799]: Failed to look up alias 'nfs': Function not implemented
    Looking at the Wiki for Systemd under troubleshooting it actually has an example of trying to work through this exact issue. Following that I tried
    journalctl _PID=1799
    systemd[1]: system-modules-load[1799]: Failed to look up alias 'sg': Function not implemented
    systemd[1]: system-modules-load[1799]: Failed to look up alias 'nfs': Function not implemented
    which I already mentioned. At this point that bit of the Wiki stopped being useful.
    Looking up on Google Failed to look up alias 'nfs': Function not implemented returned this thread from two years ago. Running “lsmod |grep sg” or $lsmod |grep nfs” returns nothing, but it also returns nothing on this laptop I'm using as well, so I don't imagine that is useful. Also, “# grep nfs /lib/modules/4.0.1-1-ARCH/modules.alias” returns a “Nosuch file or directory” error.
    Searching for something on 'sg' turned up https://bbs.archlinux.org/viewtopic.php?id=165361, which was also not useful.
    As a sort of last resort I tried https://wiki.archlinux.org/index.php/Do … the_kernel
    I reboot and boot into my fallback installation, running 3.19.3-3, mount the partition with my main Arch on it, and arch-chroot into it.
    I downgraded linux, and nvidia, exited chroot, and rebooted hoping to the Great Bacon that I didn't do anything too damaging. After all, my back ups are more than a week out of date.
    This worked. I'm still getting those annyoing (they are only annoying right?) error messages I mentioned earlier. My system seems fine, if somewhat out of date.
    Still, the question remains, “why did that happen, and how do I actually fix it?”
    [edit2=solution]
    There were two problems. First, my grub.cfg entry was pointing to the wrong UUID. I fixed this by regenerating it. Then I noticed the UUID in the grub menu itself (during the boot prosses) did not match what was in grub.cfg. To fix this I reinstalled grub.
    Last edited by nstgc (2015-05-05 12:07:30)

    Well, I took snapshots, not back ups but they work well enough for this, and rsynced /boot/ to where it use to be, moved/renamed the subvolume boot, and commented out the appropriate line in fstab. I also deleted that other /boot from before. I unmount /boot, and regenerate my grub.cfg. If my machine still boots, I'll try for an upgrade.
    grub.cfg now looks like

    It seems as if the lines you mentioned, Scimmia, have changed. I'll take that as a good sign.
    [edit] System still boots. Trying for the upgrade.
    [edit2] Still can't use Linux 4.0. I'm getting the same errors as before.
    [edit3] Successfully downgraded.
    [edit4] I looked through /etc/mkinitcpio.conf and there isn't anything in there that isn't in my laptop's. I don't know if this will help, but here is the output of "pacman -Q"

  • Intel HD Graphics 5500: Wrong rendering with KMS

    Hi folks,
    I've been struggling to get my new laptop – a PC Specialist Lafité with Intel Core i7-5500U – configured properly and wonder if somebody could help me out.  The problem seems to be in the graphics configuration. This is the controller:
    00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09) (prog-if 00 [VGA controller])

    AFStatus: TP-
    Kernel driver in use: i915
    Kernel modules: i915
    In either early or late KMS start, essentially what I see during boot is the boot messages starting to get drawn from the top of the screen, at some point they briefly stop being drawn (as if services are still loading) and then continue until the screen's height is filled, when the screen flashes blank and new messages get drawn from the top. I also see random pixels appear singly all over the screen, in different colours. This behaviour happened when I was first running the Arch installation, until I realised that KMS might be the problem and added "nomodeset" (and later "i915.modeset=0", which made no difference) to the kernel parameters. However, before booting into my Arch pendrive, the laptop booted into a sort of windows installer / agreement signing (in UEFI, presumably) which did get rendered correctly.
    This potentially leads me to think that, before I nuked the existing partitions in readiness for my Arch install, there was some firmware or driver in there that made the HD 5500 just work™. Could this be true? I'm still getting my head around UEFI and what it lets you do. With this in mind, I tried making a new EDID to give the GPU a good idea of what kind of screen it should be drawing to, but that made no difference.
    Strangely, if I boot up with KMS and get to X (with root doing startx on the stock configuration), neither /var/log/Xorg.0.log nor glxinfo seem to think anything's the matter from what I can tell:

    Likewise xrandr seems happy with the way things are going:
    Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767
    eDP1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 293mm x 165mm
    1920x1080 60.00*+ 40.00
    1400x1050 59.98
    1280x1024 60.02
    1280x960 60.00
    1024x768 60.00
    800x600 60.32 56.25
    640x480 59.94
    HDMI1 disconnected (normal left inverted right x axis y axis)
    VIRTUAL1 disconnected (normal left inverted right x axis y axis)
    I tried boteium's suggestion to force xrandr to redraw things (or signal them to get redrawn, however it works) by rotating the picture, but I still had the same weirdness of slow drawing, random coloured pixels and now "smudging" with the open xterm instances. It's as if hardware acceleration is not enabled and, I imagine, the GPU is blindly trying to draw whatever it can to the screen without preparing the complete picture first (if that's what they do at all).
    For completion's sake – and I'm sorry for all these walls of text – here's my pacman -Q, just in case anyone could (hopefully) spot a silly mistake on my part:

    Sorry to double-post, but I'm coming around to the idea that it's a UEFI issue. My understanding now is that, if I want to use UEFI, the kernel's EFISTUB needs to be loaded by certain EFI firmware that gives the kernel information about the hardware, which I unfortunately lost when creating my partitions. The only EFI file I have in /boot is "/boot/EFI/gummiboot/gummibootx64.efi". Should this be enough to boot as UEFI? Am I understanding this right? Something else that makes me think I'm missing some essential stuff that was originally installed, is that some items as reported by dmidecode say "To be filled by O.E.M.". Since I've just bought this system pre-built from an OEM, I would have thought that they'd fill that in, and that the EFI firmware is the place to do it.
    Also, one thing I forgot to mention above is that I changed the BIOS setting Advanced→Launch PXE OpROM policy from "Legacy" to "UEFI" before booting into the Arch iso. Could this have anything to do with KMS not working (during the installation and until now)? I didn't try booting with "Legacy", but if we could confirm that booting as UEFI is what broke KMS during installation, maybe that could be worth mentioning in the wiki.

  • Nautilus will not Start after system update

    I just updated my system with "pacman -Syu" and it now will not open the nautilus file manager. Looking inside the journal it shows the following error:
    gnome-session[647]: Window manager warning: Log level 16: AT-SPI: Error in GetItems, sender=(null), error=Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

  • LVM Volumes not available after update

    Hi All!
    I haven't updated my system for about two months and today I updated it. Now I have the problem that I cannot boot properly. I have my root partition in an LVM volume and on boot I get the message
    ERROR: device 'UUID=xxx' not found. Skipping fs
    ERROR: Unable to find root device 'UUID=xxx'
    After that I land in the recovery shell. After some research I found, that "lvm lvdisplay" showed that my volumes where not available and I had to reenable them with "lvm vgchange -a y".
    Issuing any lvm command also produced the following warning:
    WARNING: lvmetad is running but disabled. Restart lvmetad before enabling it!
    Anyway, after issuing the commands and exiting the recovery shell, the system booted again. However, I would prefer being able to boot without manual actions.
    Thanks in advance!

    # in this array. For instance:
    # MODULES="piix ide_disk reiserfs"
    MODULES=""
    # BINARIES
    # This setting includes any additional binaries a given user may
    # wish into the CPIO image. This is run last, so it may be used to
    # override the actual binaries included by a given hook
    # BINARIES are dependency parsed, so you may safely ignore libraries
    BINARIES=""
    # FILES
    # This setting is similar to BINARIES above, however, files are added
    # as-is and are not parsed in any way. This is useful for config files.
    FILES=""
    # HOOKS
    # This is the most important setting in this file. The HOOKS control the
    # modules and scripts added to the image, and what happens at boot time.
    # Order is important, and it is recommended that you do not change the
    # order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
    # help on a given hook.
    # 'base' is _required_ unless you know precisely what you are doing.
    # 'udev' is _required_ in order to automatically load modules
    # 'filesystems' is _required_ unless you specify your fs modules in MODULES
    # Examples:
    ## This setup specifies all modules in the MODULES setting above.
    ## No raid, lvm2, or encrypted root is needed.
    # HOOKS="base"
    ## This setup will autodetect all modules for your system and should
    ## work as a sane default
    # HOOKS="base udev autodetect block filesystems"
    ## This setup will generate a 'full' image which supports most systems.
    ## No autodetection is done.
    # HOOKS="base udev block filesystems"
    ## This setup assembles a pata mdadm array with an encrypted root FS.
    ## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
    # HOOKS="base udev block mdadm encrypt filesystems"
    ## This setup loads an lvm2 volume group on a usb device.
    # HOOKS="base udev block lvm2 filesystems"
