Hi Gerhard,
It /could/ be the port itself if you have changed the cable and disk..
Yes, but it is very unlikely. I have written TB of data there without any
problems. Anyway this is my 3rd exchanged SAMSUNG disk ...
Have you tried loading the disk with dd and seeing if you can reproduce the
problem? You are getting the same error I get generally, I can recommend
turning OFF NCQ first and see if the problem goes away.
# Define DISKS.
cd /sys/block
DISKS=$(/bin/ls -1d sd[a-z])
# Disable NCQ on all disks.
echo "Disabling NCQ on all disks..."
for i in $DISKS
do
echo "Disabling NCQ on $i"
echo 1 > /sys/block/"$i"/device/queue_depth
done
I tried to disable NCQ on all disks and tried to rebuild the raid, but it
still failed to rebuild with the same error message.
I also tried the nolapic kernel parameter without success.
/dev/sda: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
/dev/sdb: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
/dev/sdc: 5 Reallocated_Sector_Ct 0x0033 091 091 010 Pre-fail Always - 413
/dev/sdd: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
/dev/sde: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
/dev/sdf: 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0
The only thing is that the Reallocated_Sector_Ct is still >0 on /dev/sdc
(keep in mind this is my 3rd new Samsung disk on /dev/sdc and I had up to
3000 Reallocated_Sector_Ct on previous disks in < 1 day !!!).
Should I replace the disk a fourth time?
When you search in google you find a lot of threads with the timeout
problem. Might this be a software issue?
Any ideas?
Thnx.
Ciao,
Gerhard
