Sorry about that, wasn't thinking at the time and just wanted to get this up and going as quickly as possible :( If this happens next time I'll be more careful to keep more evidence. I think multi-fs in the same rados namespace support would actually helped here, since it makes it easier to create a newfs and leave the other one around (for investigation) But makes me wonder that the broken dir scenario can probably be replicated by hand using rados calls. There's a pretty generic ticket there for don't die on dir errors, but I imagine the code can be audited and steps to cause a synthetic error can be produced. -- Milosz Tanski CTO 16 East 34th Street, 15th floor New York, NY 10016 p: 646-253-9055 e: [email protected] -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
