Hi all, We have this scenario: - A datacenter - 1 Server running kvm VMs: * 1 Openfiler to distribute hard disk to other VMs (stores VMs and VMs's data) and other uses * Other VMs... - DRBD configured to replicate Openfiler's volumes as primary - B datacenter - 1 Server running kvm as backup for center A failure events - DRBD configured to serve as backup of Openfiler so VMs can be restarted in case of failure with updated data. It also works as primary. Both centers are connected through wireless connections (500 Mb/s) which is good for our requirements. Nevertheless, there is a ping of 300 ms because of multiple routers in whithin... We have been experiencing multiple split-brain situations and we don't know why... perhaps the link is down for a while but I don't understand the source of the problem as although they are primary-primary, one of the servers should never write to disk as all machines are kept on datacenter A, is this assumption right?, is this split-brain just "conceptual" telling that network was lost but no real uncoherences have appeared?. Under such asumption.. would it be ok to apply autorecover?. Any light on all this?, any alternatives?, any experience under such scenario?.
