Hi Shalika,

 

Do you see any events in the Application Event Log for those Volumes on the MA Server?

Have you run chkdsk on the Mountpoints for these Mount Paths? - You can get the Volume guid from mountvol, then run a chkdsk against that volume GUID.

 

Regards,

Michael

If NTFS detects issues with the file system it turns on the “dirty” bit which forces a check disk operation next reboot. Commvault detects this as we don’t want to write to a potentially damaged volume and unknowingly put data at risk. You can see more info about the dirty bit and how to turn it ‘off’ here: https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/fsutil-dirty

  • A volume's dirty bit indicates that the file system may be in an inconsistent state. The dirty bit can be set because:

    • The volume is online and it has outstanding changes.

    • Changes were made to the volume and the computer was shut down before the changes were committed to the disk.

    • Corruption was detected on the volume.

  • If the dirty bit is set when the computer restarts, chkdsk runs to verify the file system integrity and to attempt to fix any issues with the volume.
