O.K...I found the help section in 1.2.7 that talks about using paths...however
I still cannot get this to work:
root@hqceph1:/usr/local/ceph-install-1# ceph-deploy osd prepare
hqosd1:/dev/disk/by-path/pci-0000:02:00.0-scsi-0:2:1:0
usage: ceph-deploy osd [-h] [--zap-disk] [--fs-type FS_TYPE] [--dmcrypt]
[--dmcrypt-key-dir KEYDIR]
SUBCOMMAND HOST:DISK[:JOURNAL] [HOST:DISK[:JOURNAL]
...]
ceph-deploy osd: error: argument HOST:DISK[:JOURNAL]: must be in form
HOST:DISK[:JOURNAL]
is '/dev/disk/by-path' names supported...or am I doing something wrong?
Thanks,
Shain

Alfredo,
Do you know what version of ceph-deploy has this updated functionality
I just updated to 1.2.7 and it does not appear to include it.
Thanks,
Shain

Alfredo,
Thanks a lot for the info.
I'll make sure I have an updated version of ceph-deploy and give it another
shot.

Indeed it does!
`ceph-deploy osd --help` got updated recently to demonstrate how this
needs to be done (an extra step is involved):
For paths, first prepare and then activate:
ceph-deploy osd prepare {osd-node-name}:/path/to/osd
ceph-deploy osd activate {osd-node-name}:/path/to/osd
