[Lustre-discuss] Lustre 2.2 hanging.

[Colin Leavett-Brown]

I am seeing a lot of messages of the form:

kernel: INFO: task tgt_recov:4175 blocked for more than 120 seconds.
kernel: INFO: task loop0:15314 blocked for more than 120 seconds.
kernel: INFO: task mount:15326 blocked for more than 120 seconds.

I am running:

SL6.2 x86_64
2.6.32-220.4.2.el6_lustre.x86_64

Seems to be fairly easy to reproduce:

cd /lustreFS
mkdir mnt
wget http://www.nimbusproject.org/downloads/ubuntu10.10.gz
gunzip ubuntu10.10.gz
kpartx -a ubuntu10.10
mount /dev/mapper/loop0p1 mnt

To free things up I have to reboot. And then I'll get several:

kernel: INFO: task tgt_recov:4175 blocked for more than 120 seconds.

messages during the remount of lustre.

Anybody else seeing this?
