LVM -- or raid -- shouldn't normally be able to cause scsi-level 
errors.  ext2 might complain about hoked up data, but the scsi
stuff happens at the circut level.  looks like your disk got fried.

you might want to try running a low-level scsi check on the disk
(non-destructive, hopefully).  this would also be a really good
time to verify your backups...
