Hi Phil & others:
the pvfs2 module was loaded and dmesg |grep pvfs reported the module
version as the same as the other code. There were some other messages
in the log; unfortunately, they were lost when I had to back all my
chnages out last night to restore the cluster to operation (which
included rebuilding my experimental node).
I looked at them, and they seemed inconsequential (very similar to the
log). They were posted to #pvfs2 IRC channel yesterday, between 11am
and 12:30pm PDT (UTC-7). I don't seem to have a log, though.
I'll see if I can perform some tests today, but as I need to down pvfs
for the entire cluster so I can upgrade the server, then the client to
test, its kind of a big deal and needs to be scheduled. I don't have
a similar dev environment.
Would there be some time we could meet on IRC and do some real-time
debugging so as to minimize the times I need to take down the cluster?
