Bug#404589: kernel-image-2.6.8-3-k7: access to large RAID arrays on Adaptec 2400A RAID controller with dpt_i2o module causes system hang

2006-12-26 Thread Robert Boeck
Package: kernel-image-2.6.8-3-k7
Version: 2.6.8-16sarge6
Severity: critical
Justification: causes serious data loss


The system has built in an Adaptec 2400A RAID controller with two 80 GB
disks attached which are configured as RAID 1. The controller is handled
by the dpt_i2o module.

In this configuration everything works fine. (The RAID array is
exclusively used for data storage [samba server], the operating system
is installed on a separate single IDE disk which is attached to the
motherboard's IDE controller).

When I attach two 500 GB disks to the controller instead of the 80 GB
disks and configure them as RAID 1 array, the problems begin.
Partitioning the array with cfdisk works, building the file system with
mkfs.ext3 or mkreiserfs works, too. But copying data with cp to the
partition causes cp to hang after some time and some files were copied.
With an other console, changing to the directory in which the partition
on the array is mounted causes this console to hang, too. 'shutdown -h
now' (again in an other console) displays the shutdown-message, but the
system doesn't do a shutdown.

After a hard reset, it depends on the file system, whether there are
data on the array or not. With ext3 there are none of the copied files
on the array, with reiserfs there are the files on the array which were
copied before cp hung.

I tried to google for the problem and found a post on google groups
which seems to be related to the problem. The message-id is

With the 2.4.27-2-386 kernel, everything seems to work, even with the
500 GB RAID array.

Hi Steve,

thanks

Hi Robert,

Will you be able to test the linux-2.6 snapshots as Dann asked?  This
appears to be the last release-critical bug in the kernel that's not
accounted for for etch.


I'm sorry, I cannot do any more tests. I built in a 3ware Escalade
7006-2 controller, which solved the problem. Since the machine is a
productive server and the 500 G disks are productive now, I cannot use
the disks for tests anymore.

Regards,
Robert Böck
