On my DC (Server 2003 R2 SP2) I have 3 volumes with VSS taking snapshots twice daily. 2 of the 3 work flawlessly. The other one has started failing regularly with several errors:
ID: 7001 VssAdmin: Unable to create a shadow copy: The shadow copy provider had an error. Please see the system and application event logs for more information.
Command-line: 'C:\WINDOWS\system32\vssadmin.exe Create Shadow /AutoRetry=5 /For=\\?\Volume{b50a79eb-7418-49f6-a185-679e1fdebc9a}\'.
ID: 12298 Volume Shadow Copy Service error: The I/O writes cannot be held during the shadow copy creation period on volume \\?\Volume{b50a79eb-7418-49f6-a185-679e1fdebc9a}\. The volume index in the shadow copy set is 0. Error details: Open[0x00000000], Flush[0x00000000], Release[0x80042314], OnRun[0x00000000].
ID: 12310 Volume Shadow Copy Service error: The shadow copy could not be committed - operation timed out. Error context: DeviceIoControl(\\?\Volume{b50a79eb-7418-49f6-a185-679e1fdebc9a} - 000001C0,0x0053c010,00AA0048,0,00AA1050,4096,[0]).
I am running version 5.2.3790.3959 (srv03_sp2_rtm.070216-1710) of vssvc.exe
A reboot allowed 2 successful snapshots on this volume but then it failed again. There are no errors from a vssadmin list writers command and the only provider listed from a vssadmin list providers is:
Provider name: 'Microsoft Software Shadow Copy provider 1.0'
Provider type: System
Provider Id: {b5946137-7b9f-4925-af80-51abd60b20d5}
Version: 1.0.0.7
Is there a hotfix I am missing or a newer version of VSS i should install? Or perhaps this is related to the volume since VSS works fine on the other two volumes.
Your assistance is appreciated!
Thanks,
