Re: (S)ATA exceptions, disk frozen

Hi,

we have about 60 opteron servers running sarge amd64 with a
2.6.20.3 vanilla kernel (previously they were running 2.6.18.1;
I installed the newer kernel in the hope that the problem would disappear).

At a rate of about 1-2 per week the SATA disk in a server freezes and
I have to reboot. Because of the statistical nature of the effect (and since
smartctl -a doesn't display any errors) I conclude that this is not a hardware
issue but a software problem.

Any idea how to narrow down the problem?

Thanks, Thomas

this may not turn up anything, but is there any consistency in when
these events happen? are there any cron or routine tasks that happen at
these times?>
