Replace /dev/sda with your disk... smartctl -t short /dev/sda and after some minutes smartctl --all /dev/sda If all went OK then the status is =C2=ABPASSED=C2=BB, and you could try the extended or long tests with smartctl. I had a bad disk here, which resulted in slow IO, but not complete failure. Smart detected this immediately. Sorry, I do not know how to check disks with LVM. Urs
