On Ubuntu 1310 with Ceph 0.72, after manually putting in the patch from
http://tracker.ceph.com/issues/6966
I was able to create my dmcrypt OSD with:
ceph-deploy disk zap tca14:/dev/cciss/c0d1
ceph-deploy --verbose osd create --dmcrypt tca14:/dev/cciss/c0d1
Looking at the mount points with df showed:
df | grep ceph
/dev/dm-1 70568868 53976 70514892 1%
/var/lib/ceph/osd/ceph-0
/dev/dm-3 70568868 52412 70516456 1%
/var/lib/ceph/osd/ceph-3
/dev/dm-5 70568868 60852 70508016 1%
/var/lib/ceph/osd/ceph-4
/dev/dm-7 70568868 35284 70533584 1%
/var/lib/ceph/osd/ceph-5
/dev/dm-9 70568868 36736 70532132 1%
/var/lib/ceph/osd/ceph-6
I tried to use whole new blank disk to create two separate partition
(one for data and second for journal)
and use dmcrypt, but there is a problem with use this. It's looks like
there is a problem with mounting or
formatting partitions.
OS is Ubuntu 13.04 with ceph v0.72 (emperor)
I used command:
ceph-deploy osd prepare ceph-node0:sdb --dmcrypt
--dmcrypt-key-dir=/root --fs-type=xfs
[ceph-node0][WARNIN] INFO:ceph-disk:Will colocate journal with data on
/dev/sdb
