These are a few of the commands I have ran so far...
cat /proc/mdstat
Personalities : [raid0] [raid1] [raid5] [raid6]
Md1 : active raid1 hdd1[2] hdc1[1] hda1[0]
104320 blocks [3/3] [UUU]
(Just so you know... That's missing the "needed" MD2)
lvm pvscan
- No matching physical volumes found
lvm lvscan
- No volume groups found
lvm vgscan
- Reading all physical volumes. This may take a while....
No volume groups found
lvm vgchange -ay
No volume groups found
lvm vgdisplay
No volume groups found
fdisk -l /dev/hda
Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 *

fdisk -l /dev/hdc
Disk /dev/hdc: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 *

raidstart /dev/md1
- No errors, just returns command prompt
raidstart /dev/md2
- No errors, just returns command prompt
Sooooooooo, Then I tried to start fixing things.....
mdadm --assemble -m 2 /dev/md2 /dev/hda2 /dev/hdc2 /dev/hdd2
I get
Mdadm: Bad super-minor number: /dev/md2
mdadm --assemble --run -m 2 /dev/md2 /dev/hda2 /dev/hdc2 /dev/hdd2
Mdadm: failed to RUN_ARRAY /dev/md2: Invalid argument
Then... Looking at
cat /proc/mdstat
Personalities : [raid0] [raid1] [raid5] [raid6]
Md1 : active raid1 hdd1[2] hdc1[1] hda1[0]
104320 blocks [3/3] [UUU]
Md2 : inactive hdc2[1] hdd2[2]
312367616
Unused devices: <none>
Then... Trying to get a little more pushy...
mdadm --stop /dev/md2
mdadm --verbose --assemble --run -m 2 /dev/md2 /dev/hda2 /dev/hdc2
/dev/hdd2
Mdadm: looking for devices for /dev/md2
Mdadm: /dev/hda2 is identified as a member of /dev/md2, slot 0
Mdadm: /dev/hdc2 is identified as a member of /dev/md2, slot 1
Mdadm: /dev/hdd2 is identified as a member of /dev/md2, slot 2
Mdadm: added /dev/hda2 to /dev/md2 as 0
Mdadm: added /dev/hdd2 to /dev/md2 as 2
Mdadm: added /dev/hdc2 to /dev/md2 as 1
Mdadm: failed to RUN_ARRAY /dev/md2: Invalid argument
Ok... So... That is where I quit... Any Idea what kind of hope I should
be holding out for?
