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.
