USB unassigned drives XFS error

[dcoens]

This is my tail log.  I was copying my data to my usb drive as a backup.  I'm getting this error when tring to bring it online.  Is their a XFS repair command or something?   I have no idea about a duplicate UUID.

Ok...  I used xfs_admin -U generate /dev/sdm1 command.  It seemed to fix it.  I am not sure why this would have happened in the first place.

Was just going to suggest that     You can also do the same from the GUI using UD by clicking on the Settings icon for the drive.

 

You can get this issue if the drive in question was previously used in the main array and was not reformatted as it will have the same UUID as the drive that has replaced it.   Was that what happened?
