< Unspecified file name > file is larger than the maximum size supported by the data store ' < indeterminate datastore >

Hello

I use vSphere4 and I'm having problems, create snapshots of virtual machines.  I get the following error when I try and take a snapshot...

File & lt; filename not specified & gt; is larger that the maximum size supported by the store data "& lt; not stated the store data & gt;

If I check all disks assigned to the virtual machine, the block sizes are ok.  All the disks are of block size of 1 MB and less 60GB, except one that is 600GB and a 4 MB block size.  There are also free space on each data store with being less 5,30 Go which I guess should be much more than enough to create a snapshot.

In addition, whenever I try and create a snapshot, it creates a file called SERVER - Snapshot1.vmsn, 2, 3, 4 etc. on the main data store.

Is it possible that because of the single disc of 600 GB, VMware prevents me from taking a snapshot?

Here is the config...

See the attached file for disk configuration information.  Operating system drive is the drive where the snapshots are created.

Basic disks refers to all disks assigned to the virtual machine. Given that, by default, the snapshot is stored the vmx file, this data store should be able to potentially create a VMDK your largest disk size, assuming that you change every block in the vmdk.

In your case, it should support a snapshot that can potentially reach 600 GB to one of your drives, and so needs a block of size on the VMFS volume to support this. You can redirect the snapshots to another logic unit number and so to work around this problem (Storage VMotion is another option) limitation.

Trust, this clears up a little.

  • < unspecified file name > is greater than the taken maximum size supported by the data store ' < indeterminate datastore >

    Hello

    I made a mistake.

    Block size was set at 2 MB, vmdisk 500 GB value has tried to bring to 600, do you have a message that it was not possible. VMDK was set to 512 GB after that operation is completed. The server is Windows 2003. the 11 additional GB, which is not allowed is visible to the guest OS. But I have not developed the partion with diskpart.

    The problem is that this snapshot of the operation failed. This is an easy way to decrease the vmdk to the original size of 500 GB (if possible without turning off). Without destroying the files.

    Thank you very much

    Solution 1 works if you have a second data store with the appropriate block size (4 or 8 MB)

    Solution 2 - as you said - requires additional disk space and stop times

    A possible solution (3) would be an upgrade to vSphere 5 allowing - after the upgrade of VMFS-5 data store - virtual disks with up to 2 TB less 512octets regardless of the size of block that exists. However, you must ensure vcenter Server as well as guests, access to the database are upgraded before the upgrade of VMFS data store. Also make sure that any 3rd party applications (eg backup) you use, support vSphere 5.

    Since you mention a LUN to Solution 2, I assume you are using a shared storage. You do not have the opportunity to present a different LUN for guests, that you could get in shape with the block of adequate size and then cold migrate the virtual machine to it?

  • TimesTen 11.2.2.5.0 - backup (.bacxyz) files created by the ttBackup much larger than the data store

    Hello

    have a question about the files generated by the internal ttBackup utility on our systems.

    We have a pair of storage of data replicated with DS following sizes on disk in a two-way manner:

    -rw - rw - 1 timesten, timesten 48922624 24 August at 12:45 tt41data.ds0

    -rw - rw - 1 timesten, timesten 48922624 24 August at 13:00 tt41data.ds1

    -rw - rw - 1 timesten, timesten 38895616 24 August at 12:46 tt41data.ds0

    -rw - rw - 1 timesten, timesten 38895616 24 August 12:31 tt41data.ds1

    Looking at the backup files generated via /ttBackup - force - dir xxx

    You can see on the first:

    -rw - 1 timesten, timesten 48922624 24 August at 12:34 tt41data.0.bac

    -rw - 1 timesten, timesten 720 24 August at 12:34 tt41data.sta

    -rw - 1 timesten, timesten 475060224 24 August at 12:34 tt41data.0.bac245

    While on the second:

    -rw - 1 timesten, timesten 38895616 24 August at 12:34 tt41data.0.bac

    -rw - 1 timesten, timesten 83904512 24 August at 12:34 tt41data.0.bac248

    -rw - 1 timesten, timesten 720 24 August at 12:34 tt41data.sta

    So while the .bac file is consistent with the size of the DS on the disk, the bacxyz shows a huge difference on the second case.

    Undersand it is an internal utility, but I would like to understand the significance of this file, did not find much in the documentation.

    Also tried using - type streamFull and the generated files differs for a factor of 4 x.

    Check the number of tuples, they are pretty much the same thing, as the ds size seems to imply, but cannot understand the enormous size of the file bac.xxx on the second node, what is the significance of this file?

    Thanks in advance!


    Mike

    The .bac file is essentially a copy of the most recent checkpoint file (ds0/ds1) while the .bacxyz file is a single file that is a fusion of all the files (tt41data.lognnnnnn files) transaction logs needed to recover from this checkpoint file. So depending on the State of your database (in terms of number of log files present on the drive and which of them are actually required) by the time you take the backup of the file .bacxyz can vary in size from very small to very large. If you want to make sure the file .bacxyz has the smallest possible size, you must issue a checkpoint manually, and wait until it finishes before running the ttBackup command.

  • < Unspecified file name > file is larger than the maximum size supported by datastore '< indeterminate datastore >.

    I know that this issue has much spoken in the forums, but the answers are always to make sure that your block sizes are set to 8 MB - mine are already. Let me explain:

    I have a virtual machine with a large amount of connected storage - something along the lines of discs 10 x 1.99 to. Sit all VMDK on partitions of the VMFS of 8 MB of size block, including the configuration of the VM (location of the pagefile).

    Every time I try and snapshot of the virtual machine, I see the "< unspecified file name > file is larger than the maximum size supported by the data store ' < unspecified datastore >. All other virtual machines instant fine, but any other VM has a similar amount of storage as the VM problem.

    I have now moved the configuration files of the virtual machine to a new partition VMFS 5 of 1.91 TB, but the instant error persists. Most of the readers is sitting on VMFS 3.33 or 3.46. It will take me a while to move all VMFS 5 to see if that solves the problem.

    My VMDK and volumes are smaller than 2032GB. I don't understand why, it's be a problem.

    Anyone have any ideas?

    Although ESXi 5 supports larger LUN as a raw physical devices (up to 64 TB), the maximum size of a virtual disk has not yet changed.

  • Failed to create snapshot... file is larger than the size max...

    I'm getting the "file is greater than the maximum size supported by the store of data... »

    I read the KB figure I can move the. VMX file to another data store to get the snapshot to work.

    But I'm having a hard time understanding why this is happening.  I want to avoid this in the future.

    My data store is 67,50 GB of capacity, with 16.92 GB free.

    Block size is 1 MB.

    I understand that 1 MB BS may comprise a maximum of 256 GB.

    Could someone please explain in English how Vmware is the calculation that the 16 GB of free space is not enough?

    Please be nice

    Thank you.

    Yes, that is the question, 272 GB is too large for the size of block 1 data store MB. Front of vSphere 5, all snapshots are created in the home of the virtual machine folder by default. With vSphere 5, this has changed and now snapshots are created in the same folder as the virtual disks from their parent.

  • file is larger than the maximum size supported by the vmware data store: snapshot fails

    Hello

    I'm having a few problems when creating a snapshot either by Veeam/vSphere client...  Here are the details...

    VM is connected to lun 2 TB RDM in virual Server files mode. The configuration file is located on the datastore to vmfs with 750 GB (block size of 8MB)

    I'm not sure whether the size of the data store creates a problem or anything else.

    All advice is appreciated...

    Thank you

    What is the exact size of the RDM? A snapshot requires little additional space for hard metadata. Please take a look at http://kb.vmware.com/kb/1012384 (section: load calculation required by the snapshot files). For your ROW, this means, if the ROW is greater than 2032 GB, you will not be able to create a snapshot.

  • Suddenly my mail is displayed in alphabetical order by name of shippers, rather than the date of receipt?

    It is not uncommon, since it is unlikely that you are using the same characteristics for your output file as your input file.

    It is virtually impossible to get an output that is the same size as your entry.

    What will you do with your output file? It is best to think in terms of your output - Blu - Ray, DVD, online, iPad, whatever - and then produce a file optimized for this device.

  • VMX file larger than the maximum size supported by the data store

    Hi all

    I seem to be getting a strange error trying to a virtual machine that is located on a snapshot VMFS5, to the data store format.

    The virtual machine (VMDK and VMX file) is installed on a thin provisioned 2 TB datastore which has the value VMFS5 formatting.  It is a data store new with no other VM on it.  I had problems in the past with the datastore block sizes (1 MB, 2 MB, 4 MB, 8 MB on VMFS3), however, I thought that VMFS5 got rid of the question, since it's all blocks of 1 MB and all files in the virtual computer are on the same data store.

    The error I get indicates that the VMX file is too large for the data store (used Im saying "unspecified file), however, if I do the independent 2 TB disk snapshots through the fine.  The virtual machine has two virtual disks, a 50 VMDK of GB and a thin 2 TB VMDK (200 GB used).  I tried fast vMotioning the VMDK and VMX to other data formatted VMFS5 stores and still get the same error.

    I'd appreciate any help and ideas.

    Thank you

    Although the block size limit is party, maximum 2 TB file size less 512octets still exists. Since a Flash disk can grow waist put in service the basic disk more overhead for the metadata, the maximum size of virtual disk - to be able to create snapshots - is 2032 GB.

    Same rules apply.  Create an another LUN with the correct block size and away files or hang the lun and recreate

  • During remediation instant failure disappear from the Manager, is the data store

    Hi guys

    I was contracted to sort a vSphere 4.1 environment and there are a few VM some with up to 4 snapshots on them and more than a year. I've been rehabilitating some of them already with the "remove all" according to vSphere documentation, and all went very well.

    I just tried to reclaim a more, it only has a single VM disk and a snapshot of what is only a few months old. The remediation process has gone wrong, and I got the following error: ' < unspecified file name > file is larger than the maximum size supported by the data store ' < unspecified datastore > root 25/05/2012 16:20:07 25/05/2012 16:20:07 25/05/2012 16:20:09.

    The data store has a block size of 1 MB and should be able to support up to 256 MB file size and disk of the virtual machine is only 84 GB, real size of snapshots is 77 GB with space set 84 GB service identical to the original size of the virtual machine.

    The server is a box of SQL2008R2, so it is quite important that he does not fail. In addition, the company used to have vCenter installed, but at some point in time ceased it to use it and are now only connect directly to the ESXi hosts themselfes.

    Does anyone have an idea how to fix this? The server seems to be working well, but if you look at the snapshot the Snapshot Manager disappeared, but the files still exist in the data store. I'll make sure that we at this time do not turn off the server.

    I also just found when comparing the .vmx files this virtual machine and another virtual machine that still has old clichés in this regard, the following differences.

    hostCPUID.0 = "0000000b756e65476c65746e49656e69".
    hostCPUID.1 = "000206c220200800029ee3ffbfebfbff".
    hostCPUID.80000001 = "0000000000000000000000012c 100800.
    guestCPUID.0 = "0000000b756e65476c65746e49656e69".
    guestCPUID.1 = "000206c200010800829822030febfbff".
    guestCPUID.80000001 = "00000000000000000000000128100800".
    userCPUID.0 = "0000000b756e65476c65746e49656e69".
    userCPUID.1 = "000206c220200800029822030febfbff".
    userCPUID.80000001 = "00000000000000000000000128100800".

    That information above, does not exist in the file .vmx for virtual machine that does not have the reclamation of the snapshot.

    Kind regards

    Niels

    OK, let's put it all together:

    ... There's a few VM some with up to 4 snapshots on them and more than a year

    ... The data store has a block size of 1 MB and should be able to support up to 256 GB file size

    ... "The file is larger than the maximum size supported by the data store

    --> virtual disks _1 and _2 _3 on different data warehouses (MON)

    Think again of what could be the cause of this error message, the only reason why I can think of is that the other virtual disks have been added after taken the snapshot, and at least one of the virtual disks has a size greater than 254 GB. (see "calculates the time required by the snapshot files system" at http://kb.vmware.com/kb/1012384)

    When you delete a snapshot with the virtual machine, ESXi creates a ' consolidate snapshot of assistance. " If this snapshot of assistance cannot be created, you will receive this error message. If this is the case you should at least be able to remove the snapshot with the virtual machine off.

    The next question is how to resolve this situation, in order to create snapshots in the future. Well, the best way - where your hardware is supported - would be upgrade to ESXi 5 and VMFS-5, that supports the file sizes of ~ 2 TB size of blocks of 1 MB unified. In the case where an upgrade is not an option you will need to either create smaller virtual disks and migrate/copy data or create new warehouses of data with a block size and migrate virtual disks.

    An alternative to the above mentioned, which adds however complexity to the configuration - potentially redirect snapshots of a store of data with the appropriate block size. See http://kb.vmware.com/kb/1002929
