I have a 2 node cluster and one of the guest VM is showing the following errors which prevents my backup jobs to run properly.
""The system failed to flush data to the transaction log. Corruption may occur in VolumeId: \?\Volume{03499d9b-dd46-11eb-94a9-00155d0a6e01}, DeviceName: \Device\HarddiskVolume20.
(A device which does not exist was specified.)"
"The shadow copies of volume \?\Volume{03499f08-dd46-11eb-94a9-00155d0a6e01} were aborted during detection because a critical control file could not be opened."
I can't seem to located \Device\HarddiskVolume20, which it may not exist nor I can find out which drive is associated with VolumeId: \?\Volume{03499d9b-dd46-11eb-94a9-00155d0a6e01.
I ran Get-Volume PowerShell command on the VM and 2 hosts, but still can't find any drive with that volume ID. Any advise and tips would highly be appreciated.

Thanks for your reply. Strangely, when I delete old volume shadow copies from an active volume, then I can run my backup without any issues.
can this issue be related to corrupt shadow copies or maybe the shadow copies storage location is getting full? but it appears that I have enough storage!
Hi,
Thanks for your reply!
Based on your description, I think it is more likely that you have corrupted copies among your old volume shadow copies. My presumption is: one of your old copies may be corrupted but your registry still keeps cetain data, then when you delete old copies, this piece of data is cleared from your registry. So you can run your backup properly. Anyway, good to hear that you have kind of solved your issue!

Hi,
Thanks for posting on your forum!
Based on your description, it seems that your Volume 20 has been lost while it is still automatically mounted in your system. You can start wbadmin, enter into command prompt and run Mountvol /R , to removes volume mount point directories and registry settings for volumes that are no longer in the system. You can learn more about this command from this article:
https://learn.microsoft.com/en-us/windows-server/administration/windows-commands/mountvol
Besides, [HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices] is used to store some information about each drive (device) that was plugged into a Windows system. Among this information is the drive letter that was assigned to this drive. Thus, if a drive is used again, it ensures that the same drive letter is assigned to the drive.
Then you can retry to operate your backup.
Thanks for your support! Hope to hear your good news soon!
