Its not used as /home at all ... Ive tried deleting partition with
parted and re-creating it, setting the raid flag on it ... after
running partprobe and blkid, output is the same, also error when adding
it into RAID array is the same? Anyone know how to change the TYPE of
the partition as seen by the blkid? This is something installer has done
so there must be a way!

Ill try to fix the RAID first, Ive seen crappy drives going into
temporary spasm and everything being OK after
. I think my problem is
due to mdadm not seeing /dev/sdb3 as valid RAID partition, so Ill try to
fix that first.
