[OpenAFS] Crash testing OpenAFS
Mon, 22 Aug 2005 10:56:41 -0700
Using 126.96.36.199-21.7 kernel (SuSE 9.3 + 1.3.87) - something was hanging Linux
in the middle of an rx packet.
Its working better now - I changed the cache from ext2 to ext3. fsck on the
cache was not allowing a clean reboot and am not using /vicepb., So far
moving about 100GB is going smoothly.
I'm running X and everything else imagineable.
Using a disk cache 10GB. Both dynroot and not.
KRB5 with aklog (the SuSE aklog needs to be replaced since it doesn't use
Apparently few users have SuSE installed.
Am compiling 1.4.0-rc1 and will re-test on another server.

Are you having troubles with the OpenAFS linux client? Are you using a
memory cache? Are you using kernel 2.6? I have been unable to reliably use
OpenAFS client 1.3.X + Kernel 2.6 (SuSE SLES and Pro 9 - 9.3) + Memory
Cache. I assumed I was the only person with these troubles as I would
expect more people to be complaining if it was widespread. When using the
above combination, I would see cache corruption and occasional crashes on
the client workstations. Switching to a disk cache eliminated all issues.
I would be interested in knowing if anyone else is seeing the same problem.
