Helen - Having the error message would be very helpful here so we know what issue were looking at. On first glance it woould appear that possibly you did not start the client process for mounting on the client machine. I think pvfs2-ping does look at a mount point at some level. I would try pvfs2-ls next time also to see if it has nothing to do with the client process/mount. The other thing I would check is to make sure the server processes are actually running and haven't failed silently. If they have failed the server logs will indicate why.
Once you have that all setup, if you still have issues let's try to get some logs or error messages if at all possible.

I built an xfs filesystem on /dev/md0 and mounted it on /pvfs2. 4. I then started the server with "/usr/local/sbin/pvfs2-server /etc/pvfs2-fs.conf -f " for the 1st time and without "-f" subsequent times. 4. On a second node (dn3, the pvfs client) I created /etc/pvfs2tab with the following line: ib://dn2-ib:3335/pvfs2 /mnt/pvfs2 pvfs2 defaults,noauto 0 0 5. Pvfs2-ping -m /mnt/pvfs2 failed. Unfortunately I did'nt capture the erroe message in time before the nodes were grabbed by my colleague. I remembered vaguely that it complained about the exported pvfs2 filesystem not initialized. 6. I verified that the IB RDMA network worked using rping. Please let me know if I have done something wrong and whether you need more info to troubleshoot. Your help will be appreciated.
