Hi,
I found the following in the logs on a client, and I think it might
be interesting to pvfs2 developers. After it happened, the client
slowly deteriorated over time. Yesterday it started losing other file
system and has to be powercycled. The machine is 4 core x86-64 (Xeon
E5410 @ 2.33GHz) running openSUSE 10.3 with kernel 2.6.25 on 8GB of
memory.
Thanks,
--andrew
