Volume Shadow Copy / Volsnap

Discussion in 'Windows Small Business Server' started by SitsWithMouse, Nov 29, 2007.

  1. Good day Team SBS

    We are experiencing a shadow copy problem on an SBS 2003 SP1 server.
    The server has 3 drives ( C, D, E ). Shadow copy on D and E works fine, but
    we are unable to get shadow copy enabled and running on C. When we try and
    enable it (Shadow Copy Tab, Enable button), it returns a dialog box error
    with the following description "Failed to create a shadow copy of volume
    C:\." "Error 0x80042306: The shadow copy provider had an error. Please see
    the system and application event logs for more information.".

    The System Log has the following Error Event
    Source: Volsnap
    Category: None
    Type: Error
    Event ID: 8

    Description: "The flush and hold writes operation on volume C: timed out
    while waiting for a release writes command."

    The Application Log has the following Error Events
    Source: VSS
    Category: None
    Type: Error
    Event ID: 12298
    Description: "Volume Shadow Copy Service error: The shadow copy could not be
    committed - operation timed out. Error context:
    DeviceIoControl(\\?\Volume{5abc1468-d301-11d9-ab46-806e6f6e6963} -

    Source: VSS
    Category: None
    Type: Error
    Event ID: 12310
    Description: "Volume Shadow Copy Service error: The I/O writes cannot be
    held during the shadow copy creation period on volume
    \\?\Volume{5abc1468-d301-11d9-ab46-806e6f6e6963}\. The volume index in the
    shadow copy set is 0. Error details: Open[0x00000000], Flush[0x00000000],
    Release[0x80042314], OnRun[0x00000000]."

    This ONLY happens on C:\ while D:\ and E:\ appear to be just fine.

    Any asisstance would be greatly appreciated

  2. Hi Sits.....

    www.eventid.net appears to have solutions for this problem.

  3. Hi Larry

    Thanks for you post. They actually point to a Microsoft Knownledgebase
    article that says this is not a serious problem and occurs due to a RAID
    reconfiguration(paraphrased). The problem is that it is a serious problem as
    the shadow copies arent working, which makes VSS not work, which in turn
    makes the backups fail.

  4. Did you work your way through the links for all three error messages?

    event 8 which is as you describe
    event 12298 and event 12310 which point to different issues.

  5. Yes, both hotfixes/updates for 12298 and 12310 were downloaded and run, but
    were already applied.

    Any other ideas?

  6. I'm sort of out of thoughts on this. I do see a couple of references to:

    Volume must be NTFS, and since this is SBS we know it is.

    Run Chkdsk and chkdsk /f /r - never to be taken lightly with a system
    partition, but worth considering. If possible you should have an image of
    the partition before doing it.

  7. also, in the original it is stated '3 drives', is it indeed 3 HDD's or some
    form of RAID and/or partitioning?

    I'd be curious to find what if anything happens if you enable SC's but
    redirect the SC area to another drive, if it's physical drives, there's not
    much use doing so between partitions on a single drive or array.
