Dear DRBD users, I'm testing DRBD 9 always using the latest source code in order test the environment and put it in production as soon as the code is stable enough. My initial problem is: my scenario demands at least 3 nodes and 2 primaries nodes, using a Distributed File system (I have choose ocfs2). I have already configured the nodes and the sincronization and the file system locking is working fine, but I couldn't find on DRBD 9 and 8.4 manuals the procedure to safely shutdown a primary node (without produce a split-brain behavior) and to shutdown all nodes without furter problems like nodes with standalone connections, outdate or inconsistent disk states. For example: when I want to shutdown all nodes I do the following steps: 1. umount file system in all nodes (umount /<mount-point> 2. shutdown the ocfs cluster (/etc/init.d/o2cb unload) 3. shutdown the drbd cluster (drbadm down <resource>) But when I restart I get this situation (1 node primary,uptodate and 2 nodes inconsistent,standalone) and the procedure "--discard-my-data" as stated on manuals doesn't work as supposed to and the only way to get all nodes working is recreating the metadata for secondary nodes. So bottom line: How to shutdown 1,2 or all nodes in a drbd9/primary-primary/3-nodes scenario without any problems? Thanks in advance, Arthur Fernandes.
