Then it really sounds like you found a bug in XFS, and ceph-mon didn't even do anything really weird to trigger it. If it's reproducible, I'm sure the XFS developers would appreciate if you straced what ceph-mon does to get to the hang, tried to do similar actions to reproduce it outside of ceph (e.g. "every time I write to this file, it hangs"), and then give them a good bug report with a dump of the filesystem, to figure out what really happened. If it's not reproducible, just reboot the machine, fsck the filesystem, and hope for the best. -- 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
