[NTLUG:Discuss] HOW?? - Remirroring a software RAID-1 that doesn't autoremirror.

[Richard Geoffrion]

OK..so there should be nothing TO it.  I should just have to reboot the box
and the raid mirror should just autorecover...only it's not.  AND since this
is on the [/] root partition I can't just stopraid, raidhotadd, or any other
raid command on the silly thing because its always active.

I don't even remember the question at this point so I'll just include some
information.  Any ideas on how to get a happy [UU] out of /dev/md1?
