XFS Volume Restore Fails to Mount

Description: XFS kernel module remembers the old UUID and refuses to mount

Cloning an XFS volume and mounting the filesystem of the cloned volume on the same node as the source volume will throw a “duplicate UUID” error or similar errors.  The cloning of the volume reflects everything from the source at the point of time of the snapshot, which also includes the UUID of the partitions within the volume.  The UUID is the unique identifier pointing to the partition, and hence it is not unique anymore with the cloned volume on the host.

This is generally not an issue when the cloned volume is attached to a different host than that of the source volume.

Error: Filesystem has duplicate UUID - can't mount

For EXT4 filesystems, even though /var/log/messages shows an error about the device appearing twice with different sysfs paths, it doesn’t throw the error when mounting the filesystem from the cloned volume.
