Ok actually my nodes are connected to 2 switches: one 1G Eth and one IB, so
the names "parapide-X-ib0" were to be used for IP over IB (the real
hostnames being "parapide-X", or even "parapide-X.rennes.grid5000.fr", which
is the output of the hostname command). I realized it was useless working
with the names ending in "-ib0" because I'm not using IP over IB in this
case.

So I deployed again PVFS using the real hostnames, but I still get the same
errors (and again, the kernel module works fine), the configuration line is
now:
/usr/bin/pvfs2-genconfig --quiet --protocol ib --ioservers "parapide-5"
--metaservers "parapide-5" --storage /tmp/pvfs2-storage-space --logfile
/tmp/pvfs2-log --fsname pvfs2 pvfs2-fs.conf
And the configuration file is attached.

I also changed the limits.conf as advised by Kevin Harms, by adding the
following line:
*                hard    memlock         unlimited
But it does change the warning (when I'm logged as user the ulimit -l
unlimited says I don't have the permissions). Also tried
*                hard    memlock         1073741824
Doesn't work either.
