Virtual Disk used Size is Zero

Hi All,
Got a 3.0.2 test environment, 2 hosts with a seperate physical VM Manager box. Been creating Xen PVM guests using both a downloaded OL5U7 template to clone from as well as using network boot to extracted iso via ftp (also OL5U7).
For the clones, I noticed the virtual disk name defaults to a 32-character string while I could name the virtual disk for the network boot method. What's the best practise for organising this? Should I leave the Virtual Disk name blank so it defaults to a 32-character string like the cloned guests?
Also, in Homes > Server Pools > Repositories > Virtual Disks, the cloned guests are showing the correct virtual disk usage but for the guests created using network boot to iso is showing zero for disk usage. The only difference I see between the 2 types of guests is the giest created using the extrated iso is using lvm for the root partition.
Is there a way to refresh the ovm manager view such that the disk usage is accurate for the guests?
Thanks.

The Manager just allows you to name new disks for display in the Manager only.

This will increase over time as more content is stored inside the image.
Is there a way to refresh the ovm manager view such that the disk usage is accurate for the guests?Refresh the repository.

  • Creating a Virtual Disk using Diskpart

    Hi, I'm trying to study for a test on Windows 7 and I'm trying to install a Virtual disk and I keep getting the same error. The drive has been "cleaned" using the diskpart utility and is a 300 gb drive. here is the code that I used and the error
    as copied from the command prompt. Any help would be great Thanks!!!!!! 
    DISKPART> create vdisk file="C:\test\disk1.vhd" maximum=24000
    DiskPart has encountered an error: The system cannot find the path specified.
    See the System Event Log for more information.

    Hi, slobodan21.
    Here is the web page that contains the CREATE vdisk command you have been trying:
    http://technet.microsoft.com/en-us/library/gg252579.aspx
    I am only guessing but... make sure you create a folder called test in the root of your C: drive.
    Good luck!

  • Server 2008 R2 Enterprise - 1 Virtual Disk - Using UEFI - 4.5 TB available - Why 2 Disk 0 - Unallocated space entries?

    Hello everyone,
    I'm building a new Dell R720 server. It has a RAID 5 - 6 x 1TB array.
    I am attempting to install Server 2008 R2 Enterprise. I used the build disc supplied by Dell.
    The BIOS is UEFI configured.
    When I launch installation of Server 2008 R2 Enterprise in the storage area it shows:
    Disk 0 Unallocated Space - 2048GB Total Size - Free Space 2048GB
    Disk 0 Unallocated Space - 2607GB Total Size - Free Space 2607GB
    I would like it to show:
    Disk 0 Unallocated Space - 4655GB Total Size - Free Space 4655GB
    I want to partition 1 600GB partition for the OS and the rest for storage of Hyper-V VM's.
    I understand using GPT to format the volume. But I haven't even allocated anything yet and it is showing 1 virtual drive as 2 entries....
    I tried to find a simple answer for what is going on here but I don't really have a lot of time to do hours of research. Just a basic answer would be good if anyone has one. I don't see an initialize option in the RAID controller itself that is of much
    help. Maybe someone has configured an R720 and has an answer already for this? It would be appreciated! We litterally need the full amount of storage allocated for the storage of the VM's as they are huge files being moved from an existing failing Hyper-V
    server.
    Thanks!

    So the answer for this; was after contacting Dell the newer generation Dell servers need to be booted up through the lifecycle controller (F10) > UEFI has to be explicitly chosen (Most of the Dell build discs are configured as MBR) and once the Lifecycle
    Wizard for OS deployment is completed Windows will detect the total amount of available space correctly. The older Dell models you have to download the Build Utility that is capable of GPT / UEFI configuration.
    Just incase anyone else runs into this it is not a Microsoft problem at all.

  • NCS Virtual Disk Re-size

    Hello,
    I wanted to know if anyone has had to increase the size of their NCS disk or if it is possible. We plan to installed the virtual appliance, but do not have the space currently for the recommended 200GBy of minimum disk space in our SANs. Can the disk size be changed in the future if we choose to give it less than the recommended amount?
    Thanks,
    Edward T. Fifer

    Hi Edward,
    The installer won't even initiate the install script before the required resources are available. In this case, for a small VM for NCS it would require atleast 200 GB space as you already found out. Unfortunately, this requirement would be regardless of whether you're doing thick or thin deployment on the VM side.

  • Oracle VM 2.2: why virtual disk must be 1GB or larger?

    I'm using Oracle VM 2.2. When I try to create a virtual disk using OVM Manager it requires that the disk be at least 1GB in size. Is there a reason for this? Or is it an arbitrary limit enforced by OVM Manager?

    OK, but it seems like this arbitrary limit provides no benefit. In my case I actually do want a small disk image. I want to use it to pass small amounts of configuration information to a VM at startup, but it seems like this won't be possible via OVM interfaces (I can't create a small private disk image, I can't import an existing disk image, etc). So it looks like I'll have to go under the covers and manipulate the VM image directly.
    Am I missing anything? Does OVM Manager provide any interfaces for passing configuration information to a VM at startup?

  • How to add a virtual disk into a 'guest VM' after VM has been created?

    Well, it was easy when one need to add a virtual disk before creating a guest VM. All need to do was to edit the template and click on disk tab and create a virtual disk.
    However the challenge comes after created a 'guest VM'. I need to add additional virtual disk into this 'guest VM'.
    This is what I did.
    Click on Repositories tab --> Under repositories--> Virtual Disks. There is a green "+" sign. Click on it. It says create virtual disk. Follow the instruction, I enter the virtual disk name, size, and select if it is spare or non-spare. Hit ok. Well, everythings seems fine.
    Next, I click on the "blue folder" icon which indicated import virtual disk. It asked me about Virtual disk download location.
    According to the manual, http://docs.oracle.com/cd/E27300_01/E27309/html/vmusg-repo.html#vmusg-repo-vdisk
    Virtual Disk download location: The URL for the virtual disk file. The URL protocols supported are HTTP, HTTPS, and FTP. For example:http://example.com/vdisks/myvdisk.img
    How can I determine what is the URL in my case?
    Where is the newly created virtual disk located? Isn't it supposed to be in Oracle Server? But it doesn't have  a http server running there.
    Please help.
    Thank you.

    Virtual disks can only be added and removed at runtime from a PVM. You don't even need to know anything special. Just create the vdisk and use the VMs settings to occupy another slot with the new vdisk.
    But as I said… this works only with PVMs, not HVMs. In case of a HVM, you will need to shut down the VM and add the disk afterwards, then fire it back up.
    The little folder with the blue down arrow is for importing an existing vdisk file from a web- or ftp server. If you have already created the vdisk, you won't need that.

  • Understanding Virtual Disks and Sparse Allocation

    1. From the doc here , i understand that allocation is fast when "Sparse Allocation" is used while creating a virtual disk and is slow when using non-sparse allocation. But does this mean that we are just talking about allocation alone? i.,e a one time activity - creation.
    2. If my repository has 1TB space , then i see that i can create 'n' Virtual Disks each with a size of more than a 1TB(i.e, lets say 3-4 VDisks each with a size of 1TB); whereas, if i use non-sparse allocation, then i have to have the sum of the sizes of the disks to be lesser than 1TB.
    FYI : I get an error if i allocate more than the space available: "OVMRU_002032E Excl-BigRepos - Repository size not large enough for new virtual disk of size: 999,999,999"
    3. When i install OVS on a RAID-1 partition(with two virtual disks - say 100GB and 400GB), then, OVS picks up the 100GB disk by default and installs in there. And this 100GB is not 'visible' henceforth. Reasons?

    1. Correct. Spare allocation means as the data is written the disk is expanded. This means, you're doing two operations as opposed to one with non sparse allocation. Thus, when writing to a virtual disk with a sparse allocation, the "write" could take longer if the disks doesn't have free space available.
    2. Too a degree.... Yes. It depends on what storage you're using. On some storage, using compression and deduplication, this is not entire accurate. But, this is independent of anything to do with Oracle VM. Many storage environments now use "virtual allocation".
    3. The default "LUN" used by by OVS can not be used for anything else. It is reserved. You will not able to use any free space on that LUN. The OVM manager expect "raw disks/LUN/shares" to used as storage. Such storage my be free of any filesystem, partition or etc. The Pools and repos necessary to run Oracle VM use a ocfs2 filesystem.

  • Can Windows Server Backup spread a single backup job across multiple disks if they are not set up as a virtual disk?

    This may be a dumb question, but I can't seem to find any definitive information after having done many, many searches.  Short question is - can Windows Server Backup spread a single backup job across multiple disks if they are not in a storage
    pool or some other RAID/JBOD structure?
    Background:
    I'm running Server 2012 Essentials with all Windows Updates installed.  I have been backing up approx 2.8TB of data (Bare Metal Recovery, C:, S: (shared folders), and system reserved) for the past year+ onto a storage pool made up of two-2TB external
    USB drives.  Backup is slow (takes approx 1.5 days to complete), but generally works.  Not surprisingly I was constantly getting capacity low messages so I decided to increase my backup storage pool by adding a 3TB drive and another spare 750GB drive
    for a total of 7.75TB.  Instead of having four separate external USB enclosures, I bot a 4-bay enclosure - Startech.com model #S3540BU33E to simplify this (or so I thought!).
    The first problem I had was adding the two new drives to the existing storage pool. I think that is because the Startech uses a JMicron USB controller that reports identical uniqueid's for all drives so only one shows up in the GUI interface for creating storage
    pools. After doing research on this, I set up a new storage pool and virtual disk using all four drives via Powershell and thought I was good. However, when the backup ran, it failed after filling the first drive, saying there was no remaining capacity. In
    reality there were three remaining empty drives and there storage pool reported almost 5TB of avail capacity. I assumed this was due to the identical uniqueid issue so I decided to try a different tactic.
    Instead of using a storage pool that combines all four disks into one virtual disk, I just added each of them to Windows Server Backup as individual drives thinking it would manage them collectively. I.e., when a drive filled up during a particular backup,
    it would just start using the next drive and so on. Apparently this was a foolish assumption because the backup failed again as soon as the first disk filled up.
    So now I don't know if this is still an issue with the identical uniqueid's or if Server Backup actually can't spread a single backup across multiple individual drives that aren't in a pool or other virtual disk implementation. Hence, my original question.
    My guess is that it does *not* spread them across individual disks, but I just wanted to get confirmation.
    Thanks

    Mandy,
    Thank you for following up on my question.
    Unfortunately the article you referenced doesn't address what I am trying to accomplish.
    The article focuses on saving the same backup job to multiple disks and rotating the disks between on and offsite for enhanced protection.  However, it still requires that an individual backup job fits on a single disk.
    What I am trying to determine is if a single backup job can span across more than one physical disk (during the backup process) without those physical disks being in some type of virtual disk implementation (e.g., storage pool, RAID, etc.).
    Thanks,
    Gerry

  • Server 2012 R2 iSCSI Target - Multiple targets per iSCSI Virtual Disk with CHAP

    Scenario I am trying to achieve is this:
    Windows Server 2012 R2 serves as iSCSI Target configured to have 1 iSCSI Virtual Disk
    2 Hyper-V servers connecting to this target with iSCSI Inistator and have multiple targets for that iSCSI Virtual Disk using CHAP
    **These 2 are nodes in fail over cluster, this iSCSI is added as a CSV.
    Issue that I have, is that you can only have 1 target per iSCSI Virtual Disk
    Both Hyper-V servers can connect to this LUN without issue when I add both initiator IDs to the target, but once I enable CHAP, you can only put one initiator ID in the "Name" field, so I can only connect from 1 Hyper-V server.
    Do you know of a way around this?

    From my understanding, "chaptest" is a single target, my goal was to make 2 targets to the same iSCSI virtual disk.
    So if you were to right click the iSCSI virtual disk that "chaptest" is assigned to and click "Assign iSCSI Veritual Disk...", then select "New iSCSI Target, and proceed with the wizard it removes the "chaptest" target
    and adds the new one just created.
    My goal was to have 2 targets to 1 iSCSI VD, but seeing your screenshot, with 2 initiators connected, that goal doesn't seem needed anymore.
    I was under the impression that the "User name" = the iscsi initiator IQN name, which had to be unique. That is why I thought I would need 2 targets.
    Thanks

  • Virtual Disk mis-reporting available size

    I have a virtual disk on my 6140 that has a total capacity of 4 TB. It has a configured capacity of 2 TB. However, it says that my maximum volume size is only 107 GB. Where is my other 1.83 TB? I had a 1.9 TB volume on this virtual disk that I deleted last week. It seems that it still thinks it is there. Any suggestions?

    I do not think you can use DU for resizing if you used a linux disk utility before. I never could do that, but am ready to learn how to do that.

  • Shrink size of virtual disk

    Hi,
    I converted physical server to virtual machine using P2V method. Now I have 150GB virtual disk which has linux host and data is consuming only 30GB, the rest is free. What would I like is to shrink vdisk size to, lets say, 40GB because I don't need any more space. Is there any way to copy only data to another vdisk within OracleVM or shrink size of the disk without losing data?
    Thanks.

    Hi, thx for help, I finally did it.
    Steps:
    1. Boot up VM that needs to be shrinked with GParted Live CD
    2. Shrinked partition(dev/hda5) so that unneeded space is left as unallocated
    3. Created new hard disk with enough space and attached it to VM
    4. Booted up with GParted Live CD and copied all partitions to new disk(except unallocated partitions)
    5. Created new VM with new disk
    6. After that, I booted up new VM with Rescue Live CD, and entered into grub:
    6.1. grub>root (hd0,0)
    6.2. grub>setup (hd0)
    7. Reboot!
    Now I have the same VM, just it's using over 50GB less space. :)
    Thanks!

  • Cluster Quorum Disk failing inside Guest cluster VMs in Hyper-V Cluster using Virtual Disk Sharing Windows Server 2012 R2

    Hi, I'm having a problem in a VM Guest cluster using Windows Server 2012 R2 and virtual disk sharing enabled. 
    It's a SQL 2012 cluster, which has around 10 vhdx disks shared this way. all the VHDX files are inside LUNs on a SAN. These LUNs are presented to all clustered members of the Windows Server 2012 R2 Hyper-V cluster, via Cluster Shared Volumes.
    Yesterday happened a very strange problem, both the Quorum Disk and the DTC disks got the information completetly erased. The vhdx disks themselves where there, but the info inside was gone.
    The SQL admin had to recreated both disks, but now we don't know if this issue was related to the virtualization platform or another event inside the cluster itself.

    We don't know if this can happen again, what if this happens on disk with data?! We don't know if this is related to the virtual disk sharing technology or anything related to virtualization, but I'm asking here to find out if it is a possibility.

  • Using a ZFS volume with encryption on as the Virtual disk in a Sparc VM

    Hi guys,
    Working my way through understanding how virtualization works in VM for Sparc. One question I thought of deals with having encryption turned on in a ZFS volume. If I create a volume with encryption ON, and then attach that volume as the sole virtual disk in a guest domain, will the virtualization still work? Has anyone else dealt with a scenario like this? I'm about to try it now, I'll report back with my findings.

    From my understanding, if you create a ZFS disk with encryption ON, mount it on Solaris, and after that present that to the VM, you should not have problems. The encryption will work between the volume and Solaris. To the guest vm, it should be transparent.

  • Unable to repair degraded Virtual disks in Storage Spaces under Hyper-V 2012 R2 Core

    Hi all,
    I am finding myself in the following conundrum. I have a storage pool under Hyper-V Core, with 2 2TB Seagate drives. 
    One of the drives completely died (wouldn't spin up, tried it in a different box, still to no avail). I sent it in to Seagate for warranty replacement, got the new drive. Installed it and went through the notions of adding it to the pool and retiring the
    one that was with "Lost Communication" status.
    Tried to repair the virtual disks that are showing as "Unhealthy-Detached", quickly get 100% complete, but the repair didnt work.
    The storage pool is in degraded state.
    Looks like metadata is corrupted.
    Followed this post to upgrade Storage Spaces to latest version:
     https://social.technet.microsoft.com/Forums/windowsserver/en-US/eead59e9-5e49-4bb6-8cbb-1dafddd9576b/unable-to-repair-degraded-virtual-disks-in-storage-spaces-2012r2?forum=winserverfiles
    Still, to no avail.
    Couple of questions:
    1) Is the data on the 3 virtual disks in state "Unhealthy: Detached" not recoverable?
    2) How can I get the storage pool back to "healthy"?
    Any help will be greatly appreciated.
