Hi, I came across the 'CTDB_CAPABILITY_LMASTER=no' and 'CTDB_CAPABILITY_RECMASTER=no' options in my quest to salvage a rather poorly performing CTDB cluster over Ceph(fs). Unfortunately, the docs provide not enough information for a clustering noop like myself. Would there be any benefit to disabling those options for a branch office node on a high-latency WAN connection?...

Folks, We use a Golang-based lock tool that we wrote for CTDB. That tool interacts with our 3.4 etcd cluster, and follows the requirements specified in the project. Question, does the external command line tool get called when LMASTER and RECMASTER are false? Given a scenario where we have a set of processes that have it set to false, then others that have it set to true, does the locking tool get called when they're set to false? IF you say the lock tool still gets called in both cases, then the docs need to be updated, and we on our...

...and running, I can transfer each ip address toward on node or the other, seamlessly. They can fence each other. But I still have one big issue : though they have been setup as clones, they don't behave identically : when shutting down node 1, node 0 takes over every part of ctdb setup (ip, recmaster, services). But when I stop ctdb daemon on node 1, though ctdb node 0 correctly stops its children daemons (nmbd, smbd and winbind) and kills itself, node 1 claims : ctdb_recovery_lock: Failed to get recovery lock on '/ctdb/.ctdb.lock' (This directory is clvm + gfs2 shared, writable a...

Yep. That looks good. These options are documented in the ctdb.conf(5) manual page. Sorry I didn't see the original message. The samba mailing list has always been far too busy f...
