Gluster users - Jun 2016 - distributed geo-rep using hostname instead of FQDN of slave node

Hi,

I just setup distributed geo replication on my two nodes replica master
glusterfs 3.7.11 towards my single slave node replica and noticed that for some
reasons it takes the hostname of my slave node instead of the fully qualified
domain name (FQDN) and this although I have specified the FQDN in the gluster
volume geo-replication create command. As my slave node is on another network
with another domain name geo replication does not work unless I manually add the
hostname to all my master nodes /etc/hosts file.


As an example this is the type of error you get due to this issue (taken from
the
/var/log/glusterfs/geo-replication/myvolume/ssh%3A%2F%2Froot%40192.168.100.101%3Agluster%3A%2F%2F127.0.0.1%3Amyvolume-geo.log
log file):


[2016-06-25 21:57:38.964888] E [resource(/data/myvolume/brick):230:logerr]
Popen: ssh> ssh: Could not resolve hostname mygeohost: Name or service not
known

I guess this is a bug in the geo replication create scripts or code and should
be addressed.

Best regards,
ML

Hi,

Thanks for reporting the issue. Please raise the bug  so we don't loose
track of this issue.
And also upload the geo-repliction logs and glusterd logs. We will look into it.

Thanks and Regards,
