I apologize that this post won't be very helpful in terms of addressing your problem, but I have used Heartbeat+DRBD+NFS in the past and based on my experience it is absolutely not worth the trouble. You can create some really sophisticated setups to failover, and sometimes it works. But a lot of the times the failover process for me got stuck because of open files or some other reason and getting it unstuck was a huge pain. Heartbeat v2 supposedly added some great features, but in practice (at least for me) it added a lot of needless complexity, and the documentation is horribly lacking. Best of luck getting it working. Perhaps I just didn't have something setup correctly, or maybe there have been improvements since two years ago when I was using it, but that was just my experience FWIW |

A qualified guess would be that your volume is not in a safe state or that it for some reason cannot be unmounted. Check /proc/drbd on both machines. Also dump your pacemaker configuration (crm configure) If you're playing with dual primaries you should really look into a filesystem with distributed locking mechanisms, like GFS+ or OCFS2. I prefer the latter one, for no apparent reason! |
