Yesterday, I installed 1.2.2 on a couple of our machines to see whether
OpenAFS is ready for prime-time (I want to get rid of NFS). The installation
worked smoothly, until I started doing some load testing on the first machine
by copying ~1.5Gig of binaries into a volume (copying the i386_linux22/dest
directory into a volume worked fine, so I thought "let's start doing some real
work"). The copying was done from an NFS-mounted directory on the same machine
where the volume physically resides.
After a while (copying around 100Mb), I got an oops (ksymoops(1) output below),
the copy process started to spew error messages, and 'ls /afs/' first
generated an error message, then I went to bed ;-), and now it shows an empty
directory.
Before going to bed, I decided to shut down the client on a different box
because it was filling the log with complaints that the server couldn't be
reached, but it oops'ed as well, also with an IPUT Bad refCount 0 on inode.
I'll probably need to reboot the server to get things going, but I'd like to
know what's causing this - I'm sort of hesitant of putting software into
production that produces oops'es :-)
Starting AFS cache scan...found 0 non-empty cache files (0%).
