sata disk failure?
Hello everybody,
I'm using an updated sid pure64 and I've got some troubles with my sata
disks, but I'm not sure if the problem is in the hardware (in disks or
maybe in the controller) or in the software... Maybe you can give me a
good suggestion :-)
Sometimes disk I/O stops and I'm just able to go to a tty and see
something like this:
ata2: command 0x35 timeout, stat 0xd0 host_stat 0x21
ata2: status=0xd0 { Busy }
SCSI error : <1 0 0 0> return code = 0x8000002
EOM ILI Current sda: sense = 70 7e
ASC= 4 ASCQ=a0
end_request: I/O error, dev sda, sector 215674327
ATA: abnormal status 0xD0 on port 0x977
ATA: abnormal status 0xD0 on port 0x977
ATA: abnormal status 0xD0 on port 0x977
My partition table is the following:
Device Boot Start End Blocks Id System
/dev/sda1 1 729 5855661 83 Linux
/dev/sda2 730 972 1951897+ 82 Linux swap / Solaris
/dev/sda3 973 1689 5759302+ 83 Linux
/dev/sda4 1690 19929 146512800 85 Linux extended
/dev/sda5 1690 7768 48829536 8e Linux LVM
/dev/sda6 7769 13847 48829536 8e Linux LVM
/dev/sda7 13848 19929 48853633+ 8e Linux LVM
Often it seems that the error begin when I'm reading some data from the
LVM part of the disk: I've got an Ubuntu on sda3 and it never crashed
(but I've never tried to access my LVM partitions from Ubuntu)
Actually I'm using just one of my two sata disks, but if I use the other
disk I've got similar errors on THAT disk, so I don't really think it's
a disk failure (I've also tried badblocks, but the disks look good)...
maybe a controller (nforce3-250) one?
I've read some pages on the Internet pointing to software errors...
The first time I saw that error I was playing with raid (mdadm): I had a
nice RAID-1 between sda and sdb, now I'm not using raid.
So... any suggestion? :-)
Thanks a lot!
Manuele
