1st WAG ?
WAG?
/dev/md/54 is 'just' raid1, without an atypical spare
It's not. It's a raid5 without any spare just like md5. Only difference
between the two is the metadata version, 1.1 vs. 1.2. And the partitions
making up md54 have a bunch of additional entries like UUID_SUB as
reported by `blkid`. More details in the discussion post.
raid5 & raid1+spare are less common.
whether autoassembly is smart enough to pick up the diffs without the explicit spec in
/etc/mdadm.conf?
again, dunno without trying.
I added `level` and `num-devices` to all entries in mdadm.conf and
rebooted. It didn't change anything. Manual assembly still freezes the
system as well.
