[Gluster-users] georeplication woes

[Maarten van Baarsel]

Hi,

I've upgraded my gluster 3.13 cluster to 4.0 on an Ubuntu 
server and it broke my geo-replication because of this missing 
file:

https://bugzilla.redhat.com/show_bug.cgi?id=1601532

However, between geo-replication dying and me finding that bugreport
I've tried multiple other things including setting up geo-rep again
so I've still got a Faulty georeplication now.

Removed it, created it again with the suggested fix in place but at 
the moment I see this error on the georep slave, in 
/var/log/glusterfs/glusterd.log:

E [MSGID: 106581] [glusterd-mountbroker.c:579:glusterd_do_mount] 0-management: Missing mspec: Check the corresponding option in glusterd vol file for mountbroker user: georep [No such file or directory]


These messages also seem relevant from /var/log/glusterfs/geo-replication-slaves/.../gsyncd.log:

Is there anyone out there that can tell me what to do with these 
error messages? I've resorted to checking out the source code 
but that road did not lead to enlightment either :(

thanks in advance,
Maarten.


[1] The gluster master is a 3-replica; the slave is a single 
volume at another physical location, geo-replication user is 
georep. main volume is called 'gl0', backup 'glbackup'.
