           Summary: Bricks offline
           Product: GlusterFS
           Version: 3.10
         Component: fuse
          Assignee: bugs at gluster.org

Hi!

I have a Distributed-Replica volume with glusterfs, it has 32 bricks
distributed in 16 machines (2 bricks per machine).  Almost every day, random
bricks get offline and I have to go to the machine that has the brick offline
and restart the glusterfs-server. After restart the service, the brick affected
go back online.

At the moment that one brick gets offline I see in the affected machines these
logs:

glustershd.log:
W [socket.c:590:__socket_rwv] 0-volume1-client-27: readv on 10.0.10.58:49155
failed (No data available)
I [MSGID: 114018] [client.c:2280:client_rpc_notify] 0-volume1-client-27:
disconnected from volume1-client-27. Client process will keep trying to connect
to glusterd until brick's port is available
I [rpc-clnt.c:2001:rpc_clnt_reconfig] 0-volume1-client-27: changing port to
49155 (from 0)
E [socket.c:2309:socket_connect_finish] 0-volume1-client-27: connection to
10.0.10.58:49155 failed (Connection refused)


storage-pool.log -> same errors as glusterhd.log

etc-glusterfs-glusterd.vol.log:
W [socket.c:590:__socket_rwv] 0-management: readv on
/var/run/gluster/17f9df49125385b6fcafaf23966f47d3.socket failed (No data
available)
I [MSGID: 106005] [glusterd-handler.c:5055:__glusterd_brick_rpc_notify]
0-management: Brick ubuntu15:/work/work2/gluster-storage has disconnected from
glusterd.
