Issue

I was called Friday night because one the storage mount point w16g-jive went off line. The gluster log on the client show it was having trouble connecting to two of the four storage nodes in the cluster. I rebooted the two nodes and everything was back to normal. This morning one of the nodes is back offline. The gluster log on the client shows connection errors and a gluster volume status shows the port for that brick as N/A. I can force the volume online but I would like to know what is going on.
