[K12OSN] RAID1 failure: need help

[Robert Arkiletian]

Wondering what I should do first. Any advice? Never been in this
situation before. System is still working fine on 1 drive. BTW
md0 is /
md1 is /home
md2 is /var
md3 is swap

[ark at server ~]$ cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb2[2](F) sda2[0]
     20482752 blocks [2/1] [U_]

md2 : active raid1 sdb3[1] sda3[0]
     2048192 blocks [2/2] [UU]

md3 : active raid1 sdb4[1] sda4[0]
     1020032 blocks [2/2] [UU]

md0 : active raid1 sdb1[2](F) sda1[0]
     12289600 blocks [2/1] [U_]

Here is where it puked in /var/log/messages
