Specifically, I must stop glusterfs-server service on the other nodes in order to perform any gluster commands on any node.

The nodes are all connected to the same switch and I also replaced it to see if made any difference. There is no issues with connectivity network wise and no firewall in place between the nodes. I can’t do a gluster volume status without it timing out the moment the other 2 nodes are connected to the switch. Which is odd. With one node turned on and the others off, I can perform some volume commands but the moment any one of the others are connected, a lot of commands just timeout. There’s no IP address conflict or anything of that nature either. Seems nothing can resolve the locks. Is there a manual way to resolve the locks?

What would be the best course of action? The data on the volume isn’t important right now but I’m worried when our setup goes to production we don’t have the same situation and really need to recover our Gluster setup. I’m assuming that to redo is to delete everything in the /var/lib/glusterd directory on each of the nodes and recreate the volume again. Essentially starting over. If I leave the mount points the same and keep the data&setup intact will the files still be there and accessible after? (I don’t delete the data on the bricks) I dont think there is anything wrong at gluster stack. If you cross check the n/w layer and make sure its up all the time then restarting glusterd on all the nodes should resolve the stale locks.

Some examples of the symptom highlighted: [2017-06-21 23:02:03.826858] E [rpc-clnt.c:200:call_bail] 0-management: bailing out frame type(Peer mgmt) op(--(2)) xid = 0x4 sent = 2017-06-21 22:52:02.719068. timeout = 600 for 192.168.150.53:24007 [2017-06-21 23:02:03.826888] E [rpc-clnt.c:200:call_bail] 0-management: bailing out frame type(Peer mgmt) op(--(2)) xid = 0x4 sent = 2017-06-21 22:52:02.716782. timeout = 600 for 192.168.150.52:24007 [2017-06-21 23:02:53.836936] E [rpc-clnt.c:200:call_bail] 0-management: bailing out frame type(glusterd mgmt v3) op(--(1)) xid = 0x5 sent = 2017-06-21 22:52:47.909169. timeout = 600 for 192.168.150.53:24007 [2017-06-21 23:02:53.836991] E [MSGID: 106116] [glusterd-mgmt.c:124:gd_mgmt_v3_collate_errors] 0-management: Locking failed on gfsnode3.

No client is able to connect after powering back the 3 nodes I have setup. Looking at the logs, it looks like there’s some sort of “Lock” placed on the volume which prevents all the clients from connecting to the Gluster endpoint. I can’t even do a #gluster volume status all command IF more than 1 node is powered up. I have to shutdown node2-3 and then I am able to issue the command on node1 to see volume status. When all nodes are powered up and I check the peer status, it says that all peers are connected. Trying to connect to the Gluster volume from all clients says gluster endpoint is not available and times out. There are no network issues and each node can ping each other and there are no firewalls or any other device between the nodes and clients. Please help if you think you know how to fix this. I have a feeling it’s this “lock” that’s not “released” due to the whole setup losing power all of a sudden. I’ve tried restarting all the nodes, restarting glusterfs-server etc. I’m out of ideas. Thanks in advance!
