I cannot stop, delete, or shrink (i.e., remove bricks from) a GlusterFS volume. I get an "operation failed" message when I try to do it. According to 'gluster peer status', all peers are connected. However, I cannot add a new peer to the pool. When I issue the 'gluster peer probe' command, the system does not issue any errors but the 'gluster peer status' indicates that the new peer is disconnected (all old ones are still connected). The only clue regarding the cause of these problems that I was able to find are the following messages in file /var/log/glusterfs/etc-glusterfs-glusterd.vol.log: [2011-09-28 20:50:12.128797] E [glusterd-handler.c:1137:glusterd_handle_cli_stop_volume] 0-: Unable to set cli op: 16 [2011-09-28 20:50:12.129604] W [socket.c:1494:__socket_proto_state_machine] 0-socket.management: reading from socket failed. Error (Transport endpoint is not connected), peer (127.0.0.1:1008) I am getting similar messages in response to the 'gluster volume stop/delete/remove-brick' and 'gluster peer probe' commands. It looks like the problem is caused by the "Transport endpoint is not connected" error for a local host but I cannot figure out what is causing this problem. Any suggestions would be greatly appreciated. PS. The volume is a 16-brick distributed volume with infiniband transport (one brick per node). The OS is CentOS 5.5. -- Dmitry Kopelevich Associate Professor Chemical Engineering Department University of Florida Gainesville, FL 32611 Phone: (352)-392-4422 Fax: (352)-392-9513 E-mail: dkopelevich at che.ufl.edu -------------- next part -------------- An HTML attachment was scrubbed...
