Description

Hi,
While trying to create a zfs mgs/mdt i get the following error.

mkfs.lustre --reformat --backfstype=zfs --fsname=lustre1 --mgs /dev/sdb

mkfs.lustre FATAL: Invalid filesystem name /dev/sdb

mkfs.lustre FATAL: unable to prepare backend (22)
mkfs.lustre: exiting with 22 (Invalid argument)

This was reported as an issue before for lustre 2.4 and was fixed then but may have come back again.

I have the following lustre and zfs packages installed
