Description:
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\VZLPBKVolumes\VZLPBKVolume{F9B7EA79-9590....For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
CAUSE
Virtual disk of VE with GUID started with {F9B7EA79-9590... is corrupted.RESOLUTION
1. List GUIDs of all VEs and choose the required one (use the script below to list all GUIDs): @echo off
for /F "skip=3 usebackq tokens=*" %%i in (`cmd /c "vzlist -ao veid"`) do (cmd /c "vzcfgt get %%i GUID" && echo is GUID of VE %%i) 2. Stop issued VE
vzctl stop VEID 3. Do copy of z:\vz\private\VEID\root.efd for emrgency cases.
4. Mount root.efd file
vzdskctl mount z:\vz\private\VEID\root.efd GUID 5. Run chkdsk on mounted root.efd
chkdsk /f \\?\VolumeGUID 6. When it's finished - unmount root.efd
vzdskctl umount GUID 7. Start VE
vzctl start VE A real life example:
vzctl stop 115
vzcfgt get 115 GUID
vzdskctl mount c:\vz\private\115\root.efd {799251BE-720C-468E-B877-913F49476001 }
chkdsk /f \\?\Volume{799251BE-720C-468E-B877-913F49476001 }
vzdskctl umount {799251BE-720C-468E-B877-913F49476001 }
vzctl start 115 Note: this approach works perfectly for additional drives, added via the Mount manager, ie drives D:\ or E:\ Use the additional drive's GUID from the c:\vz\conf\VEID.conf instead of the VE' primary GUID to perform the same operations, see GUID example for drive D: DRIVE_D="type=loopback;file=lpbk0000.efd;guid={cc4a1cb5-9f9d-47ac-a09f-0e6b87643105 };"
