Bad Recovery

Bad Recovery

[Stephen Hargrove]

I recently underwent a fiasco that is far too long to describe.  Suffice
it to say that all /dev/hd* were renamed.  I've recovered the primary
elements of a raid-5 array, and the array successfully rebuilt during the
night/day.

My array is composed of /dev/hdc1, /dev/hdg1, and /dev/hdd1.  Prior to
said fiasco, /dev/hde1 was a member of the array but got kicked from the
array.  /dev/hdd1 is a new drive that I just added to the system.  When
the array was rebuilding, it kicked hde1 and used hdd1.

I'm now unable to add /dev/hde1 as a spare.  It's there, and the system
sees it, but

# mdadm -a /dev/hde1
mdadm: /dev/hde1 does not appear to be an md device

--force results in the same message.

I rebooted the system, and now can't get /dev/md0 to mount.

# mount /stuff
mount: wront fs type, bad option, bad superblock on /dev/md0,
    or too many mounted file systems
    (could this be the IDE devide where you in fact use
    ide-scsi so that sr0 or sda or so is needed?)

I'm sure I've left out a ton of information you might need.  If you'll let
me know what's needed, I'll be glad to forward it.

Thanks.

syntax is: mdadm /dev/md<number> -a /dev/hde1

/proc/mdstat,
output of mdadm --assemble ... when you started the md0
syslog

Oh man ... I can't believe I screwed that up.  This did it.  Thanks!
