[LU-4227] mkfs.lustre allows formatting without --mgsnode

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.6.0
• Severity: 3
• Assignee: Emoly Liu
• Reporter: Andreas Dilger

Description

Was just formatting a second MDT for a test filesystem by hand, and forgot to add --mgsnode= to the mkfs.lustre options. This succeeded, but failed when the MDT was mounted:

mount -t lustre /dev/vg_sookie/lvmdt2 /mnt/mds2
mount.lustre: missing option mgsnode=<nid>

This should really be a required option for mkfs.lustre, since no target is usable without this.

I would prefer to see target initialization divided into two steps: low level formatting, and the registration with a specific Lustre filesystem. The initial step would initialize ldiskfs, and the second step would assign the index, NIDs, mgsnode, etc, and then register it with the MGS.
