Yeah; purge does remove packages and *package config files*; however,
Ceph data is in a different class, hence the existence of purgedata.
A user might be furious if he did what he thought was "remove the
packages" and the process also creamed his terabytes of stored data he
was in the process of moving to a different OSD server, manually
recovering, or whatever.

In the Debian world, purge does both a removal of the package and a
clean up the files so might be good to keep semantic consistency here?

Purgedata is only meant to be run *after* the package is

Otherwise we run into these problems...

It could be, I am not clear on what the expectation was for
just doing
purgedata without a purge.
Purgedata removes /etc/ceph but without the purge ceph
is still installed,
then ceph-deploy install detects ceph as already
installed and does not
(re)create /etc/ceph?
ceph-deploy will not create directories for you, that is
left to the
ceph install process, and just to be clear, the
latest ceph-deploy version (1.3) does not remote /etc/ceph,
just the contents.
Yeah, however purgedata is removing /var/lib/ceph, which means
after
running purgedata you need to either run purge then install or
manually
recreate the various working directories under /var/lib/ceph before
attempting any mon. mds or osd creation.
Maybe purgedata should actually leave those top level dirs under
/var/lib/ceph?
