In my Hyper-V server I get an error message in the event log:
Event ID 55
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume\\?\Volume{d8cfcca8-c935-11e1-acc4-d94f72d41a21}.
I think that the volume is an ID of a Virtual hard disk, but how do I find which one?
Things I already tried:
mountvol.exe does not list the volume;
vssadmin list writers does not show the volume.
We suspect this happens when Backup Exec makes a shadow copy of a volume as it occurs as the backups are going. But how do we see which volume on which virtual machine is corrupt?
(We have a 5-cluster Hyper-V host, cluster shared volumes based on iSCSI, runing Server 2008R2 Datacentre edition).
