Hi All,
Got a question while playing with ceph-volume
Are --block.db and --block.wal options mandatory for 'ceph-volume lvm
prepare --bluestore' command?
No formal syntax error is provided if omitted but OSD isn't prepared
with the following output:
Running command: /usr/local/bin/ceph-osd --cluster ceph
--osd-objectstore bluestore --mkfs -i 7 --monmap
/var/lib/ceph/osd/ceph-7/activate.monmap --keyfile - --osd-data
/var/lib/ceph/osd/ceph-7/ --osd-uuid

Symlinks are created but point to non-existent files:
lrwxrwxrwx 1 ceph ceph 42 Dec 17 16:46 block.db ->
/home/if/ceph/build/dev/osd5/block.db.file
lrwxrwxrwx 1 ceph ceph 43 Dec 17 16:46 block.wal ->
/home/if/ceph/build/dev/osd5/block.wal.file
Everything works fine when both parameters are provided though.
Wondering if this is a bug or I missed something?
Thanks,
Igor
