Hello List,
I'm not sure where to start tracking this down so this seems like the best place. I have a decently loaded server with the following configuration:
2.4.22 custom compiled kernel (all drivers static) 2 x 1.3Ghz P3 (ServerWorks Chipset) 2GB ECC DDR ram Adaptec aacraid controller card 7 SCSI disks in a hardware array D-link gigabit ethernet 330GB ext3 filesystem with 128MB journal (enlarged after problem appeared) OS (RH7.3 currently) is on separate software MD devices and SCSI disks. /aac0/users/home mounted on /home using -o bind
Every so often (this last time had a span of just over a week) the server will stop writing/reading nfs files to its clients (approx 8). I couldn't test this most recent time, but as of last time files could still be written locally to the nfs exported array.
This has happened since install using 2.4.18-acX (-ac needed for new style quotas at the time) and is still happening as of 2.4.22. The server has been upgraded to 2.4.23 but has only been up a few hours.
I'm attaching a pslist at the time of reboot. The loadavg was somewhere in the mid 30s. If you'll notice, quite a few scripts are stuck in D state. find_over_quota.sh (spawns repquota) runs every quarter hour, and remove_old_junkmail.sh (spawns the find stuck in D) runs 4 times per day. It seems heavy disk IO can cause it, but it's hard to tell.
Please do not hesitate to contact me for additional information.
Regards,
Dale Blount
