[PVFS2-users] client configuration with a cluster of servers

[Weikuan Yu]

Hi,

I just start playing around with pvfs2, certainly a newbie here. I have 
done a single host or cluster-based pvfs2 file system successfully.
However, there is one thing I am so wondered. That is, for a 
cluster-based pvfs2 file system consisting of multiple nodes: 
node{1-3},
When the client try to mount this filesystem, what is the possible 
choice to mount this pvfs2 filesystem.

The following runs fine:

mount -t pvfs2 pvfs2 /mnt/pvfs2 tcp://node1:3334/pvfs2-fs

but I am wondering, could it be

mount -t pvfs2 pvfs2 /mnt/pvfs2 tcp://node2:3334/pvfs2-fs #or
mount -t pvfs2 pvfs2 /mnt/pvfs2 tcp://node3:3334/pvfs2-fs

What are the difference between them as node1, node2 or node are all in 
the cluster-based servers.

BTW, it seems tricky to tear down the client-side configuration. Could 
somebody inform me what is
the correct order of stopping the client side configuration? I have 
done them in this order:

umount /mnt/pvfs2
rmmod pvfs2
kill pvfs2-client.

The client node often crushes. Am I missing something or I should do in 
a different way or order?

Thanks,

Weikuan
