Re: GlusterFS 4.1.3, Geo replication unable to setup

Hi Nico,

The glusterd has crashed on this node. Please raise a bug with core file?

Please use the following tool [1] to setup geo-rep by bringing back the glusterd
if you are finding it difficult with geo-rep setup steps and let us know if if it still crashes?

Hello,

On our dev environment we want to test GeoReplication with GlusterFS 4.1 and every attempt so far fails.
For now, we don't care (yet) about running it as a non-root user (not using the mountbroker etc).

Installed packages, both on master and slaves:
[root@clrv0000110367 geo-replication]# rpm -qa | grep gluster
glusterfs-client-xlators-4.1.3-1.el7.x86_64

On master server:

# ssh-copy-id  clrv0000110605    (one of the slave servers)
# gluster-georep-sshkey generate
# gluster volume geo-replication VOLUME2 clrv0000110605.ic.ing.net::VOLUME2 create push-pem

Several seconds later, all of the glusterd instances on the master side crash, with /var/log/glusterfs/glusterd.log such as:

---------

Note that the gsyncd_template.conf file (as found in /var/lib/glusterd/geo-replication) is empty, and was (re)created when the  gluster volume geo-replication command was issued.  (is it supposed to be empty ?)

Anyone any idea's ?
