We have two physical servers and we want to use KVM to create some VMs.
One of the VMs will contain an Oracle 12 database and we want to make it highly available.
We thought of using DRBD to synchronize the VM to the second server and combine all using Pacemaker/Corosync to have HA.
The question is : is it a good idea to synchronize an Oracle database using DRBD? I didn't find any relevant article on the net talking about this, all I found is about Mysql not Oracle.
I am not an expert of Oracle, but my concern is about the block replication and oracle databases.
