Dear all
I have a virtual pvfs2 server configured with 8 I/O nodes and
one Metadata node call cluster1. I'm trying to mount the /mnt/pvfs2
path in a remote client which it is not a I/O or Metadata Node.
My pvfs2tab:
tcp://cluster1:3334/pvfs2-fs /mnt/pvfs2 pvfs2 defaults,noauto 0 0
When i'm trying to mounte the path, I'm facing with this pvfs2 client
problem
*mount -t pvfs2 tcp://cluster1:3334/pvfs2-fs /mnt/pvfs2*
*mount: Connection reset by peer*
I tried to ping too with pvfs2-ping -m /mnt/pvfs2

Read what it says.
According to:
doc/pvfs2-quickstart.tex contains
Before you run pvfs2-server for the first time, you must run it with a
special
argument that tells it to create a new storage space if it does not already
exist. In this example, we must run the server as root in order to create
a storage space in /pvfs2-storage-space as specified in the configuration
files.
\begin{verbatim}
bash-2.05b# /usr/sbin/pvfs2-server /etc/pvfs2-fs.conf -f
\end{verbatim}
Once the above step is done, you can start the server in normal mode
as follows:
\begin{verbatim}
bash-2.05b# /usr/sbin/pvfs2-server /etc/pvfs2-fs.conf
\end{verbatim}

Failure: could not find filesystem for /mnt/pvfs2/ in pvfs2tab
