.Support for specifying a UUID when creating a GFS2 file system The `mkfs.gfs2` command now supports the new `-U` option, which makes it possible to specify the file system UUID for the file system you create. If you omit this option, the file system’s UUID is generated randomly.

Description Andrew Price 2023-03-22 09:27:11 UTC 
Upstream mkfs.gfs2 has a new -U option for specifying the UUID, which will be useful in the gfs2 Ansible role. mkfs.gfs2 is also one of only a few mkfses that doesn't have a UUID option, so this will give it a more complete feature set.

There should only be one small upstream patch to backport: https://pagure.io/gfs2-utils/c/822f230e3f60a9643c6bb4d90c48c57207ba371c.patch
Comment 5 Andrew Price 2023-05-23 10:27:34 UTC 
Testing notes: The test suite that runs at package build time contains some basic validation tests: https://pagure.io/gfs2-utils/blob/RHEL8/f/tests/mkfs.at#_178-182

Beyond that, some additional tests could be:

uuid=$(uuidgen)
mkfs.gfs2 -U $uuid ... $device
mount $device $mountpoint
grep -Hi $uuid /sys/fs/gfs2/$(basename $(readlink -f $device))`/uuid
umount $device
tunegfs2 -l $device | grep $uuid

Verified with some manual testing with gfs2-utils-3.2.0-13.el8.x86_64
