Bug in OneDiff logic? Hard to replicate...

During a OneDiff backup i see this, look at the last line, there is no such disk in the BKPMAN VM, how can it happen?

Run this and note the output

cat /vmfs/volumes/datastore1/BKPMAN/BKPMAN.vmx | grep ".vmdk"

XSIBackup just collects the information present in the configuration files

You are right, wow, seems a ghost disk, not appearing in VM settings, do you think i can safely remove that line?

Also i noticed another strange behaviour, if launch a remote backup job (other host, datastore on NAS in the internal lan, other than the datastore of the VM) using onediff, the VM *_XSIBAK are not created, is it normal? If i launch the job within then host they are created.

Yes, you can remove that line (and any other related one) if you are confident you want to remove that disk. I would sanitize the .vmx file prior to posing any other later action.

A corrupt configuration file can cause all sort of unexpected results, not only from part of XSIBackup, but from any other program accessing the VM like the vSphere GUI, vCenter, vCenter Converter, etc...

thanks, solved adding a new disk, and then removing it, from the vSphere client, the ghost disk disappeared.
