Did you tried this several times? It is possible that something got
messed up if that is the case.
ceph-deploy comes with the log level set at debug so there is little
else a user can do to ceph-deploy to
attempt to fix something that is not quite working.
What I would suggest here is to try the same commands ceph-deploy is
running on the remote host and try
and see if anything is different. Every time ceph-deploy runs a
command in the remote machine it will tell you
with: 'INFO Running command:'
Have you tried to see what is holding onto that tmp mount?
