Since you mentioned you also want to remove configuration you will need to run `purge` first and then `purgedata`. This will also mean that the packages will get uninstalled, hopefully that is not a drawback to your testing. If you are trying those commands and you are getting unexpected results, share the ceph-deploy logs so I can take a look at them and see if there is anything wrong that might need fixing. > > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
