Greetings, I'm running version 3.3.0 on Fedora16-x86_64. I have two bricks setup with a volume doing basic replication on an XFS formatted filesystem. I've NFS mounted the volume on a 3rd system, and invoked bonnie++ to write to the NFS mount point. After a few minutes, I noticed that bonnie++ didn't seem to be generating any more progress output, at which point I started checking assorted logs to see if anything was wrong. At that point, I saw that the client system was no longer able to write to the NFS mount point, and dmesg (and /var/log/messages) was spewing these warnings like crazy (dozens/second): nfs: server 10.31.99.166 not responding, still trying trying Those warnings started at 14:40:58 on the client system, but oddly stopped a few seconds later at 14:41:04. Here's the full bonnie++ output (/mnt/gv0 is where the gluster file system is mounted as an NFS client): ######## [root at cuda-ljf0 ~]# bonnie++ -d /mnt/gv0 -u root Using uid:0, gid:0. Writing a byte at a time...done Writing intelligently...done Rewriting... ######## Here's what's in the glusterfs logs at the moment: ########## # tail etc-glusterfs-glusterd.vol.log [2012-09-18 14:54:39.026557] I [glusterd-handler.c:542:glusterd_req_ctx_create] 0-glusterd: Received op from uuid: 1d3fb6c7-f5eb-42e9-b2bc-48bd3ed09e62 [2012-09-18 14:54:39.029463] I [glusterd-handler.c:1417:glusterd_op_stage_send_resp] 0-glusterd: Responded to stage, ret: 0 [2012-09-18 14:54:46.993426] I [glusterd-volume-ops.c:492:glusterd_handle_cli_heal_volume] 0-management: Received heal vol req for volume gv0 [2012-09-18 14:54:46.993503] E [glusterd-utils.c:277:glusterd_lock] 0-glusterd: Unable to get lock for uuid: e9ce949d-8521-4868-ad1b-860e0ffd8768, lock held by: 1d3fb6c7-f5eb-42e9-b2bc-48bd3ed09e62 [2012-09-18 14:54:46.993520] E [glusterd-handler.c:453:glusterd_op_txn_begin] 0-management: Unable to acquire local lock, ret: -1 [2012-09-18 14:55:47.175521] I [glusterd-handler.c:860:glusterd_handle_cli_get_volume] 0-glusterd: Received get vol req [2012-09-18 14:55:47.181048] I [glusterd-handler.c:860:glusterd_handle_cli_get_volume] 0-glusterd: Received get vol req [2012-09-18 14:55:49.306776] I [glusterd-volume-ops.c:492:glusterd_handle_cli_heal_volume] 0-management: Received heal vol req for volume gv0 [2012-09-18 14:55:49.306834] E [glusterd-utils.c:277:glusterd_lock] 0-glusterd: Unable to get lock for uuid: e9ce949d-8521-4868-ad1b-860e0ffd8768, lock held by: 1d3fb6c7-f5eb-42e9-b2bc-48bd3ed09e62 [2012-09-18 14:55:49.306844] E [glusterd-handler.c:453:glusterd_op_txn_begin] 0-management: Unable to acquire local lock, ret: -1 # tail -f cli.log [2012-09-18 14:55:47.176824] I [cli-rpc-ops.c:479:gf_cli3_1_get_volume_cbk] 0-cli: Received resp to get vol: 0 [2012-09-18 14:55:47.180959] I [cli-rpc-ops.c:732:gf_cli3_1_get_volume_cbk] 0-cli: Returning: 0 [2012-09-18 14:55:47.181128] I [cli-rpc-ops.c:479:gf_cli3_1_get_volume_cbk] 0-cli: Received resp to get vol: 0 [2012-09-18 14:55:47.181167] I [cli-rpc-ops.c:732:gf_cli3_1_get_volume_cbk] 0-cli: Returning: 0 [2012-09-18 14:55:47.181214] I [input.c:46:cli_batch] 0-: Exiting with: 0 [2012-09-18 14:55:49.244795] W [rpc-transport.c:174:rpc_transport_load] 0-rpc-transport: missing 'option transport-type'. defaulting to "socket" [2012-09-18 14:55:49.307054] I [cli-rpc-ops.c:5905:gf_cli3_1_heal_volume_cbk] 0-cli: Received resp to heal volume [2012-09-18 14:55:49.307274] W [dict.c:2339:dict_unserialize] (-->/usr/lib64/libgfrpc.so.0(rpc_clnt_notify+0xa5) [0x328ca10365] (-->/usr/lib64/libgfrpc.so.0(rpc_clnt_handle_reply+0xa5) [0x328ca0f965] (-->gluster(gf_cli3_1_heal_volume_cbk+0x1d4) [0x4225e4]))) 0-dict: buf is null!

The glusterfs daemon is currently consuming 90% of MEM according to top. thanks
