Fri Nov 9 08:38:13 UTC 2018

Hello,

All the servers and client are in version 5.0.

I have just reboot the client and the only message in the glusterd.log file from primary server, during the boot, are :
[2018-11-09 08:22:55.125849] E [MSGID: 101191] [event-epoll.c:671:event_dispatch_epoll_worker] 0-epoll: Failed to dispatch handler
The message "E [MSGID: 101191] [event-epoll.c:671:event_dispatch_epoll_worker] 0-epoll: Failed to dispatch handler" repeated 3 times between [2018-11-09 08:22:55.125849] and [2018-11-09 08:22:55.126831]

In the bricks log from primary server all show this :

The same messages appear in the log files on the secondary server

I don’t know how to interpret the message : 0-epoll: Failed to dispatch handler

What’s the version of srvstogfs-b11,srvstogfs-b11  and the client?

Have you checked the glusterd log of srvstogfs-b11 to see the reason of the disconnection?

Hello,

I just installed a new storage pool with 2 x 5 Servers in version 5.0 and I can not automatically mount the volume on the client. But it works manually.

I found that the volume is mount during the boot then dismount.

With this line in fstab srvstogfs-b11:/GFSVOL02 /gfsvol02 glusterfs defaults,_netdev 0 0 there are those logs on the client
I [glusterfsd-mgmt.c:2424:mgmt_rpc_notify] 0-glusterfsd-mgmt: disconnected from remote-host: srvstogfs-b11

I [fuse-bridge.c:5897:fini] 0-fuse: Unmounting '/gfsvol02'.
I [fuse-bridge.c:5902:fini] 0-fuse: Closing fuse connection to '/gfsvol02'

But when I add backupvolfile-server in fstab srvstogfs-b11:/GFSVOL02 /gfsvol02 glusterfs defaults,_netdev,backupvolfile-server=srvstogfs-a11 0 0 it works and logs show this :
I [glusterfsd-mgmt.c:2424:mgmt_rpc_notify] 0-glusterfsd-mgmt: disconnected from remote-host: srvstogfs-b11
I [glusterfsd-mgmt.c:2464:mgmt_rpc_notify] 0-glusterfsd-mgmt: connecting to next volfile server srvstogfs-a11

I [fuse-bridge.c:4870:fuse_graph_sync] 0-fuse: switched to graph 0

If I invert the order of the servers it also works (srvstogfs-a11:/GFSVOL02 /gfsvol02 glusterfs defaults,_netdev,backupvolfile-server=srvstogfs-b11 0 0) and logs show this :
I [glusterfsd-mgmt.c:2424:mgmt_rpc_notify] 0-glusterfsd-mgmt: disconnected from remote-host: srvstogfs-a11

I [fuse-bridge.c:4870:fuse_graph_sync] 0-fuse: switched to graph 0

Servers and Client OS : Ubuntu 18.04.1 LTS Fully update
Glustersf version : 5.0

Thank you in advance for your help
