hey, I have an application for drbd replication between a pair of EL6 servers, and I just realized that drbd is no longer built in.
googling found me this blog on doing it using ElRepo distributions... http://www.broexperts.com/2012/06/how-to-install-drbd-on-centos-6-2/
is that still best practice? or is there a better distribution?
or really... my application is a BackupPC server replicating its backup volume to a standby server (hey, no backup is really a backup, unless there is a backup of the backup, right?). is there a better/alternate way of maintaining a mirror of a backupPC volume than drbd... the backup volume is initially 8TB and could well grow to 3 times that over time. its stored on an XFS file system, under LVM, on striped raid6 volumes.
