Hello,
I got the answer from Matthieu, ipc are not freed with my stopping
script (killall).
Solution:
$ for shmid in `ipcs | grep $USER | cut -f 2 -d " "`; do ipcrm -m
$shmid; done
By the way, the rc script in the archive (examples/pvfs2-server.rc) does
not clean this either.
Regards,
Louis

Hello,
I am facing a "no space left" problem when configuring two servers
with OrangeFS 2.8.5. In my experiment, I configure two OrangeFS
servers, perform some transfers, clean the configuration and repeat
the process indefinitely. After around 1 thousand iterations with the
same two servers (same nodes and same configuration options), I have
the following situation when launching the first server:
$ /usr/sbin/pvfs2-server -a paradent-19.rennes.grid5000.fr

This is not a blocking problem for me, but I would prefer to
