Hi,
I have installed two HCI platforms.
Then I set up the disaster-recovery configuration
On source platform I did :
# gluster volume set all cluster.enable-shared-storage enable
# gluster system:: execute gsec_create
# gluster volume geo-replication *source* gnodesen2-01.example.com::dest
create push-pem
# gluster volume geo-replication *source* gnodesen2-01.example.com::dest
config use_meta_volume true
On target platform I did :
# gluster volume set *dest* features.shard enable
I then realized these two tests :
*1 - Sync data using the schedule_georep.py*
a - Use the : "python3 /usr/share/glusterfs/scripts/schedule_georep.py
source gnodesen2-01.example.com dest " command to sync data between the
volumes
b - After the sync is complete, execute "gluster volume dest set
features.read-only off"
c - Execute *import* (not create) *dest* volume on the target platform
manually through the Admin-UI, Result : The domain could not be added and
I get this error on vdsm log :

*Note :* I had to modify the line 105 from
/usr/share/glusterfs/scripts/schedule_georep.py to be able to use it with
python3 :
- ey = "_".join([func.func_name] + list(args))
+ key = "_".join([func.__name__] + list(args))
*2 - Sync data using the adminUI :*
a - Create a schedule on the adminUI and wait until the sync is complete.
b - Switch off read-only on target volume : gluster volume set dest
features.read-only off (on the target volume)
c - Execute ansible failover scripts : ansible-playbook
dr-rhv-failover.yml --tags="fail_over" command (on the ansible machine)
