XFS Filesystem has duplicate UUID problem Administration

XFS Filesystem has duplicate UUID problem Administration
If you can not mount your XFS partition with classical wrong fs type, bad superblock etc. error and you see a message in kernel logs (dmesg) like that:

XFS: Filesystem sdb7 has duplicate UUID – can’t mount
you can still mount the filesystem with nouuid options as below:

mount -o nouuid /dev/sdb7 disk-7

But every mount, you have to provide nouuid option. So, for exact solution you have to generate a new UUID for this partition with xfs_admin utility:
xfs_admin -U generate /dev/sdb7

Clearing log and setting UUID
writing all SBs
new UUID = 01fbb5f2-1ee0-4cce-94fc-024efb3cd3a4

after that, you can mount this XFS partition regularly.
