XFS Filesystem has duplicate UUID

Here’s how to fix a duplicate UUID on a XFS file system.

<pre lang="bash">
mount -o rw,nouuid /dev/sda1  /data

Mounting with nouuid will work, but not after a reboot.

To avoid a duplicate ID, run this command to generate a new UUID.

<pre lang="bash">
xfs_admin -U generate /dev/sda3
Clearing log and setting UUID
writing all SBs
new UUID = xxxxx-xxxx-xxxx-xxxxxxxxx
