From 29d7563416c0d94cf36d7e05493332aacebfa0e0 Mon Sep 17 00:00:00 2001 From: Krishnan Parthasarathi Date: Tue, 16 Apr 2013 10:36:31 +0530 Subject: glusterd: allow multiple instances of glusterd on one machine This is needed to support automated testing of cluster-communication features such as probing and quorum. In order to use this, you need to do the following preparatory steps. * Copy /var/lib/glusterd to another directory for each virtual host * Ensure that each virtual host has a different UUID in its glusterd.info Now you can start each copy of glusterd with the following xlator-options. * management.transport.socket.bind-address=$ip_address * management.working-directory=$unique_working_directory You can use 127.x.y.z addresses for binding without needing to assign them to interfaces explicitly. Note that you must use addresses, not names, because of some stuff in the socket code that's not worth fixing just for this usage, but after that you can use names in /etc/hosts instead. At this point you can issue CLI commands to a specific glusterd using the --remote-host option. So far probe, volume create/start/stop, mount, and basic I/O all seem to work as expected with multiple instances.
