I think I've found a bug in ceph-disk when running on Ubuntu 14.04 (and I believe 12.04 as well, but haven't confirmed) and using --dmcrypt. The problem is that when update_partition() is called, partprobe is used to re-read the partition table (as opposed to partx on all other distros) and it appears that it isn't smart/thorough enough to update all of the device's metadata. Specifically, ID_PART_ENTRY_TYPE isn't updated: root@ceph-osd03:~# udevadm info --query=env --name=/dev/vdd1 | grep ID_PART_ENTRY_TYPE ID_PART_ENTRY_TYPE=89c57f98-2fe5-4dc0-89c1-5ec00ceff2be running `partx -u` rather than `partprobe` does the appropriate thing: root@ceph-osd03:~# partx -u /dev/vdd1 root@ceph-osd03:~# udevadm info --query=env --name=/dev/vdd1 | grep ID_PART_ENTRY_TYPE ID_PART_ENTRY_TYPE=4fbd7e29-9d25-41b8-afd0-5ec00ceff05d I have an experimental patch here that Works For Me, but Sage wanted me to ping the list for input: https://github.com/fzylogic/ceph/commit/8c83f75392d68fbec7def8aa61f20b2c9c237571 I also want to test the new Infernalis code for this same bug (after a cursory check, I strongly suspect it's there as well), but it'll take a little bit to get another test cluster up to confirm. -- 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
