I have been playing with HA+DRBD on 2 servers and each with one hard disk installed. The server is hosting the database for other application servers.
Recently the application has failed and problem lies in the database server, the primary node. I've checked the server, network still up, I still can read the files and access to database but I cannot update anything and not even allowed to run a "shutdown -h now" or turn off the network interface - The file system has become read-only mode and heartbeat is still alive. I have no choice but to request the datacenter guy to unplug the network cables at the primary node, wait until I confirmed secondary node has taken over, then only power down the primary node. HA+DRBD works well for network failure or power failure on primary node but when it comes to this "half-dead" situation, it is driving me crazy. As the server is installed in remote datacenter, is there a better way for me to counter act this "half-dead" situation?
