Re: Too much hard drives failing



Completely off-list, but anyway. This is also happening with one
windows server we have here

The Device /device/blabla has a bad block

Albert, thanks a lot for your answer.

The only log i can trace back now is
Device: /dev/sda, ATA error count increased from 11605 to 11610
because it's stored on our RequesTracker

I have also some notes about
ATA: abnormal status 0xD0 on port 0xE407

This is taken from of those broken disks that's still attached on the
second port of one of the servers, i left it only to try figuring this
out.

I tried replacing the cables, etc. But the disks are really broken.
replacing them it works, maybe with no further errors.

Yes, i can remember about different error messages.

And i can only wait for it to happen again, if you need more logs

How did you work the 3Ware firmware thing?

Thanks a lot for the help

Pablo

Hi Pablo,

What kind of failures are these ? hardware or disk corruption/software ?

I have about 40 SM servers (with SATA2, SG 500GB etc. running FC5) also
using Reiser 3, I also had failures which I eventually traced to 3ware
controller firmware, however I have not had any hardware failures.


Thanks.
Albert.

Hello there

Im starting here because i really don't know which would the best place
to look for help. If this is not the correct list, please advise. And if
you can recommend any ML right for this, please let me know.

Words said, let's go to the point:

We have recently added 20 servers to our little farm, 7 of which were
having hard failuers on disks (SATA, Seagate, good brand new SuperMicro
boxes)

The fact is that this failures are coming up right after we decided to
move to reiserfs.

Can 7 out of 20 hard drives be defective (yes, of course, but what is
the % probability for this)?
Can this anyhow be related with reiserfs?

Sata2
Seagate
SuperMicro
Fedora core 5

Any help will be more than appreciated


Thanks a lot
