How to check the filesystem for a Windows VPS Hosting if it has ntfs errors?

The following error appears on the node in Event Viewer:

Event Type: Error

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....

CAUSE:

Virtual disk of VPS Hosting with GUID started with {F9B7EA79-9590... is corrupted.

RESOLUTION:

Check VPS Hosting.conf file to get the GUID string and perform the following, e.g

vzctl stop VPS HostingID

vzdskctl mount z:\vz\private\VPS HostingID\root.efd {GUID }

chkdsk /f \\?\Volume{GUID }

vzdskctl umount {GUID }

vzctl start VPS Hosting

A real life example:

vzctl stop 115


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

Please 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 .conf instead of the VPS Hosting' 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 };"
