I did something slightly different:
root@manies:~# cat /dev/sda > /dev/null
cat: /dev/sda: Input/output error
and in dmesg, problems show again:
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
SCSI error : <2 0 0 0> return code = 0x8000002
sda: Current: sense key: Medium Error
Additional sense: Unrecovered read error - auto reallocate failed
end_request: I/O error, dev sda, sector 39088832
Buffer I/O error on device sda, logical block 4886104
ata3: status=0x51 { DriveReady SeekComplete Error }
ata3: error=0x40 { UncorrectableError }
....
smartmontools is unfortunately not installed but I probably don't need it.
Could something else (bad cable or disk controller ) trigger these issues?
It would be great if we users had a quick way to decipher these messages.
E.g.
"Buffer I/O error on device xxxx, logical block yyyyyyy"
Usualy a disk failure, may also be caused by....
Etc...
Noone has made an "Identifying Hardware failures HowTo"?
