Description

Attempting to format ZFS OSTs we see the following error:
mkfs.lustre FATAL: spl_hostid not set. See mkfs.lustre(8)

We attempt to set hostid by using /sbin/genhostid, we confirm the ID exists, same failure. We attempt to set hostid by /usr/bin/hostid, confirm the ID exists, same failure
At this time we cannot format OSTS, system is dead.
