There >was a bug in 3.1.0 (1855) which lead to this problem, but that is fixed >in 3.1.1. Did you do all your operations on 3.1.1 or upgraded from 3.1.0?. I can tell you exactly how this happened. I added the one machine as a peer and then when I tried the volume creation line, I got the error that the system I was typing on was "not a friend," so I figured I should add it as a peer. Interestingly, that removed this error and gave me this other one. So I started fresh to reproduce the first error Creation of volume glustervol has been unsuccessful Host 192.168.1.54 not a friend (I'm typing on 192.168.1.54) Here is the debug log: [2010-12-21 00:26:20.336433] I [glusterd-handler.c:785:glusterd_handle_create_volume] glusterd: Received create volume req [2010-12-21 00:26:20.336525] D [glusterd-utils.c:484:glusterd_check_volume_exists] : Volume glustervol does not exist.stat failed with errno : 2 on path: /etc/glusterd/vols/gluste rvol [2010-12-21 00:26:20.336623] D [glusterd-utils.c:610:glusterd_brickinfo_new] : Returning 0 [2010-12-21 00:26:20.336643] D [glusterd-utils.c:667:glusterd_brickinfo_from_brick] : Returning 0 [2010-12-21 00:26:20.337176] D [glusterd-utils.c:201:glusterd_is_local_addr] glusterd: 192.168.1.54 is not local [2010-12-21 00:26:20.337197] D [glusterd-utils.c:2182:glusterd_hostname_to_uuid] : returning 1 [2010-12-21 00:26:20.337213] D [glusterd-utils.c:622:glusterd_resolve_brick] : Returning 1 [2010-12-21 00:26:20.337228] E [glusterd-utils.c:2311:glusterd_new_brick_validate] glusterd: Host 192.168.1.54 not a friend [2010-12-21 00:26:20.337243] D [glusterd-utils.c:2344:glusterd_new_brick_validate] : returning 1 [2010-12-21 00:26:20.337294] E [glusterd-handler.c:906:glusterd_handle_create_volume] glusterd: Unlock on opinfo failed [2010-12-21 00:26:20.337312] D [glusterd-utils.c:560:glusterd_volume_bricks_delete] : Returning -1
