Glusterfs, while being a nice distributed filesystem, provides almost no way to monitor it's integrity. Servers can come and go, bricks might get stale or fail and I afraid to know about that when it is probably too late.
Recently we had an strange failure when everything appeared working, but one brick fell out from the volume (found by pure coincidence).
Is there a simple and reliable way (cron script?) that will let me know about health status of my GlusterFS 3.2 volume?
