Dear OpenVZ community,
We have a system from IBM (System x3400) with an IBM ServeRAID 8K-I controller on which we are running Debian-Lenny 4.1.2-25. The kernel is openvz-kernel 2.6.26-2-openvz-686.
The containers are located on a separate ext3-partition and are mounted like this:
/dev/drbd0 on /mnt/hq-drbd-stor01 type ext3 (rw)
In particular, we experience a lockup when we try to un-mount and remount the container's partition.
The following steps work:
vzctl chkpnt 77
vzctl stop 77
/etc/init.d/openvz stop
/etc/init.d/openvz start
vzctl restore 77
But these don't work:
vzctl chkpnt 77
vzctl stop 77
/etc/init.d/openvz stop
umount /dev/drbd0
mount /dev/drbd0
/etc/init.d/openvz start
vzctl restore 77
The restore produces the lockup.
The output until it hangs:
Restoring VE ...
Starting VE ...
VE is mounted
undump...
Adding IP address(es): 10.20.60.20
Setting CPU units: 1000
Configure meminfo: 65536
Nothing more is displayed after this.
The host shows 100% CPU (system-)usage, load goes up to about 10. From our understanding, a container's processes run inside a kernel-process on the host. The container's currently active process (as far as we can tell, it's a different one on any try) takes all the CPU from the host.
OpenVZ-version is 036test001.
We already tried changing the RAID-controller driver in use from aacraid-1.1.5.2449 to aacraid-1.1.5.2467 but without any luck.
Then we tried using USB-disks instead of the dev/drbd0 where the restore worked even after re-mounting, so the issue must lie within the RAID controller.
We also tried to run a DRBD device on two USB-disks instead of using ServeRAID attached disks this constellation also works, so we can assume that DRDB is working correctly
Is this a known issue? If yes, (how) can it be solved?
Is there a way to debug this and provide you and us with more information?
Thank you for your time.,
Maximilian Csuk

| Quote: | let's increase the verbose level of vzctl utility. In /etc/vz/vz.conf please set LOG_LEVEL and VERBOSE variables both to 10.
|
Done.
| Quote: | Do you have a chance to get the pid of the process that consumes 100% cpu? What is the output of "/proc/pid/wchan"?
|
Yes. The output is "0".
| Quote: | Are there any suspicious messages in dmesg or in logs?

I am not sure, but I guess not. Please have a look:

Nothing more after this...
In dmesg, shortly before the lockup, it says:

But then, there are more and more messages showing that the particular pid is hanging. In this try, it was sendmail-mta, but others have been the cause too (like apache):
