The temporary hostname is in each ARRAY line in mdadm.conf.
I've never seen a hostname value on the ARRAY line in mdadm.conf. Are
you confusing hostname and array name?
The array name is based on the hostname.
ARRAY /dev/md/0 metadata=1.2 UUID=ca74958e:22f7fbfc:05211e6a:b4750387
name=gradstudies2:0
I later went ahead and changed the hostname and the corresponding part
of the array name and it booted. Then I changed them back. But wait...
I forgot to change the array name back! The above line is from a host
that was initially called gradstudies4, then gradstudies2, now back to
gradstudies4, and it works. So apparently it doesn't matter.
I guess it's the name on the HOMEHOST line that has to match what's in
the superblock, and since the default is <system>... well, <system>
means the local system, and I don't know if that's taken from the
superblock or /etc/hostname. But it works.
