Hi, It looks like OSD udev rules race with LVM at boot time. In a nutshell, if /var/lib/ceph is on a LVM volume different from /, udev may fire events trying to start OSDs before the LVM volume is mounted and fail. This problem has been reported a few times over the past months and I believe it is real. I don't think there is any safeguard preventing such a race and it makes sense to me that it can happen sometimes. I'd like to reproduce it reliably to assert this is the reason why it happens. And, more importantly, to figure out a fix and verify it works. So far all my attemps have failed: the OSD comes back up every time. The details about this issue are at http://tracker.ceph.com/issues/17889 If someone has ideas about how to handle this, it would be most welcome :-) Cheers -- Loïc Dachary, Artisan Logiciel Libre -- 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
