Decrease dynamic disk size through VMM 2012 R2

Hi,
Is it not possible to decrease a dynamic disk max size through VMM?
Do you really have to use the Hyper-V Manager?
Med venlig hilsen / Best regards

Just had the same issue, although related to migrating storage for a VM and managed to fix it...
Did quite a few modifications in SCVMM, but the key things that seemed to get this working was that I made sure my VMs were connected to the right virtual network and also that they had a VLAN enabled.
This was done by right-clicking the VM in SCVMM, selecting 'Properties', then 'Hardware Configuration', then select the Network Adapter -
Make sure the "Connected to a VM Network" has the right (for your setup) VM network selected, then check the "Enable VLAN" checkbox just below that and select a VLAN ID from the drop-down list. I only had one VLAN configured on
my VM Network so the selection was easy.
Once I did this the 26857 error went away and I could migrate storage.
Hope this helps !

TotalVHDCapacity attribute is returning zero in "Get-SCVMTemplate | select Name, TotalVhdCapacity" powershell command though the Vhd capacity is 20 gb in size, vmm 2012 r2

Hi All,
TotalVHDCapacity attribute is returning zero in "Get-SCVMTemplate | select Name, TotalVhdCapacity" powershell command though the template has Vhd capacity is 20 gb in size, vmm 2012 r2. I can create VM using this template too.
For other templates it is returning correct value though.
Can anyone help us understanding the root cause and the solution too.
Thanks in advance.

I booted this drive from another computer (Asrock M3A770DE mobo) and works fine, speed with dd was ~100MB/s
I also update bios on my first computer with Intel D945GSEJT (there is selected AHCI mode) still the same transfers with dd (~10Mb/s)
I have no idea what to do with it now
EDIT:
More tests with other hdd (Samsung HD502IJ), dd on mounted NTFS partition:

Physical Host Deployment on VMM 2012 R2

Hi,
We recently deployed two physical servers using VMM 2012 R2's bare metal deployment.
We used a Physical Computer Profile and a sysprep'd image which was stored in VMM's Library.
Once the servers booted up we realized that VMM had created a VHDX file on the server's physical HDD (E:, 500GB size).
This VHDX was mounted as C: and has a total capacity of 40GB!
My question is, how can I expand this VHDX's capacity whilst the server is running?
As this is a physical server I can't really shut it down and expand the drive without physically removing the drive from the server and attaching it to another computer.
When I try to expand the VHDX using powershell's "Resize-VHD" I get the below error:
Command Used: resize-vhd -Path E:\Win2012R2_disk_1.vhdx -SizeBytes 100GB
resize-vhd : Failed to resize the virtual disk.
The system failed to resize 'E:\Win2012R2_disk_1.vhdx': The process cannot access the file because it is being used by
another process. (0x80070020).
Is there any other way I can achieve this?
Thank you
Panicos

You won't be able to expand that VHDX file as is, you'll need to take the VHDX offline to expand it but you won't be able to do that easily.
The size of the VHDX comes from the original sysprep'd image. You'll need to change that. Once you've done that you can then redeploy the host using VMM.
Why do you need to change it? Are the hosts clustered? If so then VMs will be a CSV so there's no need to worry. Whilst 40GB isn't ideal it shouldn't cause an issue.
If they're not clustered is there a RAID controller on the server? If so you might want to change the LUN layout to have say 150GB LUN and a 350GB LUN for VMs.

Resizing hard drive created in Hyper-V Manager from VMM 2012 R2

Hi
We are running a lab environment with 2 Hyper-V 2012 R2 hosts with around 5-6 guests on each host. As part of the lab we have installed System Center VMM 2012 R2 and imported the 2 Hyper-V hosts.
I now have a guest running Server 2012 R2 where the system drive needs to be resized/expanded. I can't do this online from VMM but it's possible to do from Hyper-V Manager.
I assume that this is a "builtin feature" but isn't it possible to "import" the Hyper-V guests so all features are available in VMM?
Lasse
/Lasse

Online virtual hard disk resizing is only available for VHDX files that are attached to a SCSI controller.
This works fine through SCVMM console as Hyper-V manager/FailoverCluster - tested on my SCVMM.
Could you please provide more details or screenshot so that we can check this further.

Windows 2008 R2, converting to dynamic disk questions

Hello,
   I have a Windows 2008 R2 server and I want to convert the drive into a dynamic disk for mirroring. The disk currently is divided into two partitions. The C: partition which is System,Boot, Page File, etc. and the D: partition which
is data. The questions I have are:
    Can a disk with multiple partitions be created without data loss or anything?
    I know you have to reboot, but how long does it usually take to do the reboot/conversion before the server is back up?
    I want to mirror the drive to a 2nd identical disk in the server, and am planning to use Computer Management. Do I have to partition the second drive first, or will the process do it automatically?
    The server is a dedicated server that is provided by a hosting company, so I would be doing it through Remote Desktop. Can it be done that way?
Thanks.

Hi,
You can convert the drive into a dynamic disk within both local logon session and remote desktop session. The system requires reboot twice to make the conversion take into effect. You do not have to partition the second drive.
For more detailed information, please refer to the articles below:

VMM 2012 R2 Template creation fails with sysprep error via the gui, but works in powershell?

I'm in the process of trying to convert an existing gen1 VM (Win Server 2012 R2) to a VM template using VMM 2012 R2 with rollup 1. The creation keeps failing with the following error :-
"Error
(2901)The operation did not complete successfully because of a parameter or call sequence
that is not valid.Recommended ActionEnsure
that the parameters are valid, and then try the operation again."
I've checked that the local administrator account for the machine being converted to a template and it is blank as expected and in an attempt to troubleshoot I've output the template creation script via the VMM GUI and executed the commands in order which appears
to have resolved the problem, well the template finishes creation, i'm yet to deploy a machine via it?
# Create VM Template Wizard Script

-OrganizationName "My Organisation" -Workgroup "WORKGROUP" -AnswerFile $null -OperatingSystem $OperatingSystem
Now the only fields that weren't populated when I ran through the gui were FullName and Organization? Before I changed the script these two fields were just set to ""? Is that what has potentially caused the issue are they both required fields?

Your not the only one who can reproduce this. Did you ever find out what it was? I saw your post and tried your same work-around and it also worked for me via Powershell.

Has anyone managed to get a 3TB dynamic disk on Windows 2003 Server?

I just got a pair of new 3TB disks that I wanted to put on my Windows 2003 server enterprise x64 system, SP2, all updates installed.
When I first tried to convert to dynamic, I got the error "The operation did not complete" as described in this KB article
http://support.microsoft.com/kb/826823
It says there is a patch, but there is not one for x64, just x86 and ia64
I found another technet discussion here: https://social.technet.microsoft.com/Forums/en-US/winserverfiles/thread/cb62238c-b3d0-4989-b45a-ae6de6701a7b?stoAI=10
However its best suggestion is to use a product from AOMIE, but I tried that and it didn't even recognize the disk. It also suggests that one needs a better version of diskpart.exe and to try to the 32 bit version. Anyone have any experience
with that?
I also tried creating moving the disk to Windows 7 x64, making it dynamic there, but when I move the disk back to 2K3 it does not recognize it, and goes back to a 2TB partition. I also saw something about needing a 512 block size for 2K3, but W7 does
not allow anything smaller than 1K.

Hi,
During my research, if found the following artcle which also mentioned a 3TB disk should be supported in Windows 2003 SP1:
Has anyone managed to get a 3TB dynamic disk on Windows 2003 Server?
http://social.technet.microsoft.com/Forums/en-US/winserverfiles/thread/a720ae72-0c04-44dd-94c0-2e6aecce530e
So I contact the author about this issue. He said it could be caused if your hard disk is a 512e drive as the 3TB drives on the market today are normally 512e drives.
However manufacturers stopping identifying this, and if the controller is old, FSUtil will not able to identify a 512 drive but recognized it as a normal 512n drive.
Thus please provide the drive model so we could search on manufacturer's website for exact information.
Also please paste the screenshot in your reply which Satish mentioned if available.

Is Dynamic Disk supported to be added into a VM that is part of a cloud through Windows Azure Pack?

what do you mean by dynamic disk ?
Do you mean dynamically expanding VHDs ?
If you mean that than i confirm you that you can use either dynamic or fixed VHDs types (VHD and VHDx)
Fixed VHDs limitation is only in Microsoft Azure and not in Windows Azure Pack (only VHD)

What are basic and dynamic disks?

Basic disks and dynamic disks are two types of hard disk configurations in Windows. Most personal
computers are configured as basic disks, which are the simplest to manage. Dynamic disks can make use of multiple hard disks within a computer to duplicate data for increased performance and reliability.
A basic disk uses primary partitions, extended partitions, and logical drives to organize
data. A formatted partition is also called a volume (the terms volume and partition are often used interchangeably). In this version of Windows, basic disks can have either four primary partitions or three primary
and one extended partition. The extended partition can contain an unlimited number of logical drives. The partitions on a basic disk cannot share or split data with other partitions. Each partition on a basic disk is a separate entity on the disk.
Convert basic disk to dynamic disk: MiniTool Partition Wizard
Dynamic disks can contain an unlimited number of dynamic volumes that function like the primary partitions used on basic disks. The main difference between basic disks and dynamic disks is that dynamic disks are
able to split or share data among two or more dynamic hard disks on a computer. For example, a single dynamic volume may actually be made up of storage space on two separate hard disks. Also, dynamic disks can duplicate data among two or more hard disks to
guard against the chance of a single disk failing. This capability requires more hard disks, but improves reliability.

How do I create a digital frame w/o decreasing the photo size?

I want to frame my photos & upload them to my website. When I use the frame tool, it decreases the photo size & has a large background, which I don't want.

Perhaps the better title for this would've been "How do I create a digital frame w/o INCREASING CANVAS SIZE?"
I have this same problem on Elements 10 and I can't find an answer. It's not because hawaiiski is using Themes. When you apply a frame to the photo through Content > Frames, it decreases the image size on screen and increases canvas size around the framed photo. It's the checkered transparent canvas. But I just want the photo and the frame as a flattened rectangular image, as a jpg, to post in an online album. Just a simple 10 point black frame. I've searched a lot but can't find an easy and/or accurate way to do this. Is there a way to auto-crop the canvas size to the edges of the framed photo? I do the Marquee > Image > Crop that snaps to the edges, but it always leaves a little canvas on one or more sides and I have to crop again. Some people say to apply frames by increasing canvas size, but the design options are limited to solid colors, and it takes longer to do.
Why does Elements have to add the canvas around a framed photo and why isn't there an easier way to crop to the edges? I do dozens of photos at a time and can't be cropping every photos twice just for frames.

Hyper-V checkpoint disk size growth out of control

Hi,
i have hyper-v with exchange server installed on VM. i have used checkpoint in vm production. but i'v got trouble with my disk space. my vm is suddenly pause-critical because of out of disk space that used by checkpoint.
based on microsoft recommendation it's not worth to use point in production environment. if so you have to separate disk from vhd and checkpoint path.
now, im planning to delete all checkpoints. but the current condition of my local disk size is very low.
my vm size now is 300 GB then my free space only 50 GB. please tell me how much free space needed to merge while process merging the disk ? does it possible to perform delete check point with my current condition ?
please give me advice, im in very horrible situation right now.
thanks.

Hi,
Using checkpoints can result to unwanted beheviours like the one you are encoutering.
Aaik, the merge process will need a random free space depending on the avhd sizes and content.
But in your case, you VM is a production VM and the process may miss-behave.
So i highly recommand you do export your VM to another location before deleting checkooints.
Connect a disk to your hyper-v server
Shutdown your VM
Right click the VM then choose Export, and browse the place where you want to export
The exported VM will be a mix of your VHD and AVHDs (checkpoints
Now, try delete checkpoints one by one. Delete the first one, wait for merge, delete the second wait for merge... Do nkt forget, you are using windows server 2012 so kepp the VM stopped for the merge process to run.

WS2008 R2 - Invalid dynamic disk

I have a software RAID5 array in Windows Server 2008 R2. 5x4TB drives. After clean shutdown all the disks in disk management are listed as invalid. When I try to reactivate any of them I get this error message: This operation is not allowed
on the invalid disk pack.
What can I do? I've searched high and low and can't find a solution.

Hi,
Based on research, it seems a bug that Dynamic disk(s) comes back as INVALID after taking offline, or following reboot.
This bug surfaces when the size of a record in the LDM matches exactly the size of a block on disk. In this situation, volmgrx incorrectly flags the record as incomplete. After reading the whole database, volmgrx will clean all incomplete records. That’s why
we end up with an empty volume record and with a plex that’s not referenced by a volume.
In this repro, we have a record for a volume that’s bigger than 2TB, has a 3 digit number and has no drive letter (which means attributes are stored in the record). Because of this, the record size was exactly 68 bytes, which is the size available in the block
after all the headers.
If the effected Windows 2008 R2 server is Non-DPM server, we must re-create the volumes manually and restore from backup.
If the server is a DPM 2007 server, all of the dynamic disks in the DPM storage pool will be inaccessible. To avoid having to rebuild the DPM server from scratch, you can use the following procedure to clean (wipe out) the dynamic disks and recreate the DPM
replica and recovery point volumes while maintaining the rest of the DPM 2007 configuration.
WARNING: This procedure is non-reversible, and will result in ALL replica and recovery point volumes to be permanently lost. Verify with the customer that he has a >2TB volume configured before proceeding.
1) Run diskpart.exe - and issue a "list disk" command - and see which disks show the status of INVALID
2) Select one invalid disk at a time and issue a CLEAN command to wipe it out and make it a RAW disk again.
3) Select one disk at a time and convert to GPT, then Dynamic.
4) Exit diskpart.exe
5)Now add the same disks to the DPM storage pool under the management tab - disk tab.
6) From command prompt - run the following command to remake the DPM volumes - this may take hours...
dpmsync -reallocatereplica
7) AFTER Dpmsync completes, re-run diskpart.exe and save the output of the "list volume" command.
NOTE: Make the DOS window so if has a height of 9999 before running list volume - then copy the contents of the window to notepad.
8) Search the output of list volume and locate any volumes are larger than 2000 GB (2TB) - note the mountpoint path.
9) From command prompt - run mountvol.exe >mountvol.txt - then open the mountpoint.txt using notepad. Search for the path for the >2GB volumes to get the volume {Guid}
10) Use mountvol.exe to assign a drive letter to that volume.
mountvol E: \\?\Volume{bf14e9ca-d929-11dd-8f76-806e6f6e6963}
11) Repeat steps 7-9 for ANY and ALL volumes that have a volume numbers above 99, and exceed the 2TB size.
It is now safe to reboot and not experience the dynamic Invalid status for the dynamic disks. If the customer creates any more dynamic volumes that exceed 2TB - they MUST assign a drive letter or they will experience the same issue.
12) Run Consistency checks for all the data sources to get the DPM server back into a consistent state and continue protectecting the production servers.
I hope this helps.

[SOLVED] Windows Dynamic Disk support?

Hi everyone,
My question is, if it anyone knows how it is possible to mount Windows spanned drives, so I have access to the Windows data under Arch?
I am using Arch / Windows 8 dual boot with 3 drives. One SSD where the base systems are installed, and two 1TB HDDs, which I mirrored under Arch (2x700GB). I then spanned the remaining free space of the 2 drives to one dynamic disk under Windows 8.
I am also a bit confused, because of the different output of fdisk -l and lsblk -f, as the /var and raid partitions are not visible in the fdisk output and also the recognized filesystems are different? Is there a reason for that?

Hmm, is this for sure? Because I read that some people managed to do it.
I followed this ubuntu how-to http://bigli.ch/howto-access-windows-sp … th-ubuntu/ and after it didn't work, I tried it with mdadm (http://ubuntuforums.org/showthread.php?t=833653):
mdadm --build -l 0 -n 2 -c 64 /dev/md128 /dev/sdb3 /dev/sdc2
Anyhow, both ways let me create a Volume but I am not able to mount it.
EDIT: I got 2 different error messages, when I am trying to mount it:
#1

NTFS signature is missing.
Failed to mount '/dev/md128': Invalid argument
The device '/dev/md128' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
#2 ( after rebuilding the array with switched devices)

Failed to load $MFT: Input/output error
Failed to mount '/dev/md128': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

Disk size in Solaris 10

I have some confusion about disk subsystem in Solaris, i am trying to clarify from this forum.
I have recently installed Solaris 10 in one SPARC box. After i installed, the format gives the bellow output.
0 root wm 19491 - 29648 4.88GB (10158/0/0) 10239264
1 swap wu 0 - 4062 1.95GB (4063/0/0) 4095504
2 backup wm 0 - 29648 14.25GB (29649/0/0) 29886192
From the above output, is the size of my disk is 14 GB ?, or the size of my disk is 14+2+5=21 GB ?
I am trying to learn ZFS, so i want another partition in this disk so that i create ZFS on that partition.
I have gone to single user mode by using CD. I assumed that, from the above "format" command output, i thought i have 21GB of disk size and 14GB of free space. So i created another partition with 14GB. Now the format command gives bellow output.
0 root wm 19491 - 29648 4.88GB (10158/0/0) 10239264
1 swap wu 0 - 4062 1.95GB (4063/0/0) 4095504
2 backup wm 0 - 29648 14.25GB (29649/0/0) 29886192
3 reserved wm 0 - 29127 14.00GB (29128/0/0) 29361024
When i am creating ZFS, it given me a warning that the the partition i have specified is spanned into root partition (first partition), and it mentioned to use "-f" option.
With "-f", it created successfully.
If i assume now that the size of my disk is 14GB only then,
(1) how come two partitions are pointing to the same area in the disk ?
(2) How come two different filesystems are pointing to the same area ?
Please anyone clarify my doubts. Thank you.

Assuming a standard labeled disk it is standrad practice to have section/slice 2 being 'whole disk' for purposes of 'backup'. That would tend to indicate you have a 14GB disk. A prtvtoc /dev/dsk/c?t?d?s2 (change the ?s to the right values) will give a little more on the disk geometry.
In the display from format column 4 is the start cylinder of the partition and column 5 is the end cylinder. From the first set out output it looks like cyclinders 4063 to 19490 are not allocated
In the second set you have created a new slice (section 3) that overlaps both sections 0 and 1 - which is generally considered to be bad!
