A brand new Dell server running Windows 2008 R2 now issues the following errors in the event log :
Log Name: System
Date: 26-8-2010 5:00:50
Event ID: 55
The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume \Device\HarddiskVolumeShadowCopy2.
There are two similar messages for HarddiskVolumeShadowCopy2 and ..7.
Looking at the time stamps, Windows Server Backup seems to trigger these errors, as Windows Server Backup is scheduled to run at 5:00.
The server is used as a Hyper-V host only, and is very critical.
I do not know how \Device\HarddiskVolumeShadowCopy2/7 relates to actual volumes like C: and D: on which you can run CHKDSK.
I obviously did this already, and on all the volumes CHKDSK completed without any errors.
Does anyone know how critical this is, and how to fix this ?
