ceph-deploy osd: error: argument HOST:DISK[:JOURNAL]: must be in form HOST:DISK[:JOURNAL]

The actual error is due to the colons in the by-path name. The argument parser is using colon as a delimter. One possible solution is to add parameters --data-path and --journal-path for this case.

With the by-id path which does not have embedded colons:
