I have a DRBD setup that needs to be uninstalled.
The DRBD system crashed a while ago after having too many split-brains, right now the master server (virtual machine) is running my asterisk phone service as a standalone.
The server in question is running asterisk a2billing database which was initially mirrored between two servers: a master and a slave.
I want the DRBD on the master server to be completely uninstalled without data loss.
At the end of this project, I expect the services on this server to continue running as normal with no trace of DRBD.
