Hi all,
I'm new to this list and to the pvfs2 program. I'm using it on our home made
cluster (9 nodes) running an openMosix kernel 2.4.22-3 and Fedora Core2.
I've installed it with one node running as meta server , PVFS2 server and
data servers and all the others like data servers.
I've also compiled and installed the module.
This is my actual configuration:
1)on all nodes I've an entry in /etc/fstab like this:
tcp://om1:3334/pvfs2-fs /mnt/pvfs2 pvfs2 default,noauto 0 0
2)i've added at the rc.local these lines:
insmod /lib/modules/2.4.22-oM3src/kernel/fs/pvfs2/pvfs2.o
/home/Application/pvfs/sbin/pvfs2-client -p
/home/Application/pvfs/sbin/pvfs2-client-core
mount -t pvfs2 tcp://om1:3334/pvfs2-fs /mnt/pvfs2
3) I've enbled the default service for the startup on all the nodes
/etc/init.d/pvfs2-server
I'm encountering some problems with its usage:
if I start the server (/etc/init.d/pvfs2-server start) everything seems ok
but on the server the /tmp/pvfs2-client.log appears with this errors:
[E 16:57:50.651742] msgpair failed, will retry:: Broken pipe

[E 16:58:00.851750] *** Out of retries.
[E 16:58:00.851769] getattr_object_getattr_failure : Connection refused
However it seems to work: i can write on the /mnt/pvfs2 , make dirs, and so
on with the normal commands cp,mkdir and so on .
But during the day something go wrong infact the next day I never can see
the /mnt/pvfs2 without restarting the server and looking on the
/var/log/messages
i see:
