Can you please provide core dumps and log messages from those MDS crashes? Getting tickets filed at http://tracker.newdream.net/projects/ceph with the relevant information is what will help us fix your problems. Recovery, where not automatic, depends very much on the crash you saw. We'd be glad to help, but need more information to do so. -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
