Looking here there are docs for active/active. But for active/passive it just says it will use DRBD. I don’t see anything in /etc/gitlab/gitlab.rb that would obviously relate to DRBD, so I guess that has to be installed and configured outside of OmniBus. I do see stuff on setting up Redis Sentinel for master/slave, within the active/active documentation. Is that just for automatic failover in an active/active configuration without a separate load balancer?
I have two VMs and big NFS volume mounted to both. I can follow the active/active doc on NFS configuration but I can’t tell if that’s adequate for active/passive (ie if it depends on the shared pgsql and shared redis instances).
Any pointers/writeups would be appreciated.
