Hi all, I am planning my new gluster system and tested things out in a bunch of virtual machines. I need a bit of help to understand how geo-replication behaves. I have a master gluster cluster replica 2 (in production I will use an arbiter and replicatied/distributed) and the geo cluster is distributed with 2 machines. (in production I will have the geo cluster distributed) Everything is up and running and creating files from client both replicates and is distributed in the geo cluster. The thing I am wondering about is: When I run: gluster volume geo-replication status I see both slave nodes one is active and the other is passive. MASTER NODE MASTER VOL MASTER BRICK SLAVE USER SLAVE SLAVE NODE STATUS CRAWL STATUS LAST_SYNCED --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- gluster1 interbullfs /interbullfs geouser ssh://geouser@gluster-geo1::interbullfs-geo gluster-geo2 Active Changelog Crawl 2018-02-06 11:46:08 gluster2 interbullfs /interbullfs geouser ssh://geouser@gluster-geo1::interbullfs-geo gluster-geo1 Passive N/A N/A If I shutdown the active slave the status changes to faulty and the other one continues to be passive. MASTER NODE MASTER VOL MASTER BRICK SLAVE USER SLAVE SLAVE NODE STATUS CRAWL STATUS LAST_SYNCED ---------------------------------------------------------------------------------------------------------------------------------------------------------------- gluster1 interbullfs /interbullfs geouser ssh://geouser@gluster-geo1::interbullfs-geo N/A Faulty N/A N/A gluster2 interbullfs /interbullfs geouser ssh://geouser@gluster-geo1::interbullfs-geo gluster-geo1 Passive N/A N/A In my understanding I thought that if the active slave stopped working the passive slave should become active and should continue to replicate from master. Am I wrong? Is there just one active slave if it is setup as a distributed system? What I use: Centos 7, gluster 3.12 I have followed the geo instructions: http://docs.gluster.org/en/latest/Administrator%20Guide/Geo%20Replication/ Many thanks in advance!
