Hi lejeczek,

Try stop force.

gluster vol geo-rep <mastervol> <slavehost>::<slavevol> stop force

I think something broke:

Hi,

The following steps needs to be followed when a brick is added from new
node on master.

1. Stop geo-rep

geo repl which master volume had a brick removed:

~]$ gluster volume geo-replication GROUP-WORK
10.5.6.32::GROUP-WORK-Replica status

MASTER NODE    MASTER VOL    MASTER
BRICK                                  SLAVE USER
SLAVE                            SLAVE NODE    STATUS
CRAWL STATUS     LAST_SYNCED
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
10.5.6.100     GROUP-WORK
/__.aLocalStorages/3/0-GLUSTERs/GROUP-WORK    root
10.5.6.32::GROUP-WORK-Replica    10.5.6.32     Active
History Crawl    2017-02-01 15:24:05

~]$ gluster volume geo-replication GROUP-WORK
10.5.6.32::GROUP-WORK-Replica stop
Staging failed on 10.5.6.49. Error: Geo-replication session
between GROUP-WORK and 10.5.6.32::GROUP-WORK-Replica does
not exist.
geo-replication command failed

10.5.6.49 is the brick which was added, now part of the
master vol.

2. Run the following command on the master node where passwordless SSH
   connection is configured, in order to create a common pem pub file.

     # gluster system:: execute gsec_create

3. Create the geo-replication session using the following command.
   The push-pem and force options are required to perform the necessary
   pem-file setup on the slave nodes.

     # gluster volume geo-replication MASTER_VOL SLAVE_HOST::SLAVE_VOL
     create push-pem force

4. Start geo-rep

Thanks and Regards,
Kotresh H R

dear all

should gluster update geo repl when a volume changes?
eg. bricks are added, taken away.

reason I'm asking is because it doe not seem like gluster is
doing it on my systems?
Well, I see gluster removed a node form geo-repl, brick that
I removed.
But I added a brick to a vol and it's not there in geo-repl.
