How can I solve “XFS Filesystem has duplicate UUID” error on my Linux server/Desktop?. If you get this error message in kernel dmesg logs, it means you cannot mount your XFS partition.

To bridle this, you can mount your XFS filesystem at runtime using nouuid option with the mount command.

sudo mount -o rw,nouuid /dev/sda3  /mnt

If you reboot your solution, this solution won’t work. You have to use nouuid every time you want to mount. For a permanent solution, generate a new UUID for this partition using xfs_admin command-line tool:

$ sudo xfs_admin -U generate /dev/sda3
Clearing log and setting UUID
writing all SBs
new UUID = 95d271cc-2987-43cd-abbb-bf44eddf158d

After the generation of a new UUID, you can mount the affected partition normally.
