Hi there...
I'd created a 2 gluster vol and another 1 gluster server acting as a backup server, using geo-replication.
So in gluster01 I'd issued the command:
gluster peer probe gluster02;gluster peer probe gluster03
gluster vol create DATA replica 2 gluster01:/DATA/master01-data gluster02:/DATA/master01-data/
Then in gluster03 server:
gluster vol create DATA-SLAVE gluster03:/DATA/slave-data/
I'd setted the ssh powerless session between this 3 servers.
Then I'd used this script
like this
georepsetup

Then I reboot the 3 servers...
After a while everything works ok, but after a few minutes, I get Faulty status in gluster01....
There's the log
