Description Hans de Goede 2009-09-14 21:11:44 UTC 
Running a command like:
mdadm --assemble /dev/md0 --uuid=.... --run --auto=md --update=super-minor \
  /dev/sda /dev/sdb /dev/sdc /dev/sdd

Results in the metadata on the disks getting corrupted and the command failing
because "superblock on sda has disappeared"

I guess this is one to forward upstream, still filing it in RH bz to have a
bugnr to reference in the anaconda workaround patches.

Upstream version 3.0.3 is supposed to resolve this issue.
