Hey everyone,

I just got one of these today:

Nov 10 16:07:54 stormy kernel: sd 0:0:0:0: SCSI error: return code = 
0x08000000
Nov 10 16:07:54 stormy kernel: sda: Current: sense key: Medium Error
Nov 10 16:07:54 stormy kernel:     Add. Sense: Unrecovered read error
Nov 10 16:07:54 stormy kernel:

Nov 10 16:07:54 stormy kernel: end_request: I/O error, dev sda, sector

Nov 10 16:07:54 stormy kernel: Read-error on swap-device (253:1:743808)

My question is this: I have RAID00 set up, but don't really understand 
it well. This is how my disks are set up:

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                      1886608544 296733484 1492495120  17% /
/dev/sda1               101086     19877     75990  21% /boot
tmpfs                  1684312   1204416    479896  72% /dev/shm


Which one is having the trouble? Any ideas so I can swap it out?
