Unfortualy I can reproduce this at will just by trying to mkfs -t ext3
on one of the box's second drive.

A couple of weeks ago we added a second hardisk to our Dell 750's

SATA controler (lspci output from a slightly less uptodate box...)

Ata Maxtor 6Y080M0 SCSI sda 0
Ata Maxtor 6V250F0 SCSI sdb 0

(using the ata_piix driver...)

We have 10 of these boxes with RHEL 3 on an even with the latest
(updated yesterday 2.4.20-40? ie update 7) version the situation is
unchanged.

I wasn't going to post the issue to LKML as it in our case it should
be a redhat problem but if you are seeing the same thing they may be
some value in adding my information here... I will be adding this to
redhats bugzilla ... soon ;)

What seems to happen is that mkfs will try and write to the drive
using the normal

(From strace)

_llseek(3, 72613699584, [72613699584], SEEK_SET) = 0
write(3, "\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 32768

but this write then "never" returns...

from the echo t > /proc/sysrq-trigger output

mkfs.ext3 R F6EA8000 3872 22820 22819 (NOTLB)

The value of R varies with it sometime being 00000001 or a number

As you can see from the printk's here this error continues and the for
every access (write?) to the drive you just have to wait for a
timeout.

ata1: command 0x35 timeout, stat 0xd1 host_stat 0x61
ata1: translated ATA stat/err 0xd1/00 to SCSI SK/ASC/ASCQ 0xb/47/00
ata1: status=0xd1 { Busy }
SCSI disk error : host 0 channel 0 id 1 lun 0 return code = 8000002

Additional sense indicates Scsi parity error

ATA: abnormal status 0xD1 on port 0x177
ATA: abnormal status 0xD1 on port 0x177
ATA: abnormal status 0xD1 on port 0x177

For us this also seems to be blocking the access to the other drive?
so we are left with a effectively dead box....

We have seen this effect on 3 of the 10 boxes so far (with different
triggers) but it is 100% repeatable on this one box this way.

It looks to me like ether we should be clearing an error status after
we have got it or the drive should clear it automatically but it
clearly isn't. As such all subsequent accesses just timeout repeating
the already seen error...

Obviously this last paragraph is random wild speculation on my part :)

Anyone got a handle on this one?

Samuel

ps we cant upgrade to the latest and greatest (ie anything other than
rhel3) on these boxes but if we are showing the same symptoms then
maybe it is useful... and we have a great test case here for any
fixes...
