gery,
Since you can (obviously) boot and
since the system (obviously) works (albeit in degraded mode = limping with 1 of 2 disks working)
you basically seem to have "no immediate operational" problem (right now).
Here is your problem:
A single partition of md1 is dead:
device /dev/hda2
raid-disk 0
device /dev/null
failed-disk 1
should be:
device /dev/hda2
raid-disk 0
device /dev/hdc2
raid-disk 1
Let's first assume hdc2 was just "kicked out" briefly...(you may check your syslog ...)
Log into the SME with putty, try (omit #):
# cat /proc/mdstat >dataa.txt
(just to save)
#
/sbin/raidhotremove /dev/md1 /dev/hdc2#
/sbin/raidhotadd /dev/md1 /dev/hdc2
then check:
#
cat /proc/mdstat if you see a (U_) (not working) then save things to (maybe) show us:
# cat /proc/mdstat >datab.txt
save the partition data:
# fdisk -l > datac.txt
If the raid1 called md1 works = fine
... it may however happen again and you find out the reason (CABLE ?!) or better buy a new 2nd disk ...
install new hd on IDE1 master (where is your CD-ROM?)... boot direct to single user or
# shutdown now
# fdisk /dev/hdc
...identical to hda incl. the all important raid label "fd" on hdc1 hdc2 hdc3 (maybe more)
Now either reboot - and look that it's resyncing with
# cat /proc/mdstat
(it should !) or manually
# /sbin/raidhotadd /dev/md0 /dev/hdc1
# /sbin/raidhotadd /dev/md1 /dev/hdc2
# /sbin/raidhotadd /dev/md2 /dev/hdc3
If things don't turn out ...give us more data (as shown).

Reinhold
P.S.: Install the DarrellMay "Raidmonitor" stuff - it helps in a standard SME configuration as yours (seems to be)...
