Hi all,
I'm having stability problems with my setup.
Here's my setup
Two 24 bay supermicro servers (x8dth-6f) full with 24x Western Digital
2TB SATA RE4-GP disks.
The OS on both nodes is Debian Lenny with the backports
linux-image-2.6.32-bpo.5-amd64 kernel, the OS resides on a SSD.
I created 4x 8TB software raid5 sets (md0/1/2/3) containing 5 disks
each. The four remaining disks are hotspares
Then i created 4x DRBD volumes of the raid sets with the other server.
Using pacemaker and the iSCSITarget/iSCSILogicalUnit RA's I created 4
targets/lun/failover ips on top of the 4 DRBD volumes.
Each DRBD target/lun has it's own subnet and a dedicated 1gbit ethernet link.
I compiled the stable version v1.4.20.2 of IETD from the tarball from
the stable ietd website.
After a while of operation (sometimes a few days, sometimes a week)
the system freezes and I have to hard reset the system to get it back
online.
Pacemaker does a failover to the second node and then that node
freezes also after a while, sometimes instantly, sometimes it takes
longer.
I see these call traces in the syslog:

I see messages about the e1000 driver and iscsi_trgt so that's why i
sent this to these mailing lists.
Sometimes I get swapper: page allocation failure. order:0, mode:0x402
It only arises when there is heavy network IO to the system.
What is causing these freezes? Is it some kind of memory leak because
it only happens after a while and not instantly?
Is this a known problem?
I tried the following:
1) Put in more RAM, the system had 4GB RAM and I upgraded to 16GB on
both nodes. This doesn't seem to have any effect.
Ps. the log above is from a virtual (vmware) instance of the same
OS image and the same issue arises in the virtual machine (512MB
memory).
2) I reverted to the lenny stable kernel linux-image-2.6.26-2-amd64
kernel and then there are no freezes, but with this kernel the
performance is much lower
then with the 2.6.32 kernel, and the system load seem to get much
higher on heavy load. I'd like to know the cause of this and keep
using the 2.6.32 kernel.
3) I tried using a different NIC (Intel Pro/1000 PT Quad port server
adpater) using the e1000e driver and I have the same issue with that
NIC.
4) I will try using the latest stable linux intel e1000e drivers
(v1.3.17) from the intel site, i already compiled them but didn't have
enough time to get results (freezes).
5) Could it be possible that ethernet flow control could solve this
issue? Maybe the storage can't handle the IO's and now I don't have
flow control enabled on the switch. I am just guessing here.
6) Googling around I found that other users have these issues with
different NIC drivers/kernels and that it is not only on debian.
Here's a link to a ubuntu bug report which doesn't provide a solution
or cause: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/164018
If more info is needed I'm willing to provide.
Maybe other mailing lists need to be informed?
Kind regards,
Caspar Smit
