I was wondering if anyone could help me. I am running glusterfs 3.3.0 over rdma on ubuntu 12.04 server. <br><br>Basically, I had a single glusterfs server that was used by two host servers for running a bunch of vms. The host servers used nfs to mount the glusterfs mount point. I've added a new server with the hope to replicate data. The server was added fine and the clients could mount the mountpoint which had both servers. <br><br>Following that I've ran "ls -laR /mountpoint" on the client side to kick off the self heal process so that all the data is copied across to the second server. Following a few seconds delay I started seeing file server contents from the ls command. This lasted about 10 seconds after which point the mountpoint froze on both clients. However, I can see data being copied to the new storage server while the mountpoints were still hanging. I've waited about two hours, but the mountpoints were still frozen.<br><br>Does anyone know what the problem could be?<br><br>After about three hours I've had to stop the glusterfs service on the newly introduced server as I had to turn on the infrastructure. After the service stopped, the mountpoints came back and started working again.<br><br>I was wondering if it's possible to add new bricks without the client mountpoint hangs? How can I find out what the problem is?<br><br>Many thanks<br><br>Andrei<br></div></body></html>
