Description
capturing the rename of cluster steps in tracker, once verified can use used for docs update.
For an existing host, the removal process should be as simple as
- stop the daemons on the host
- rename /etc/ceph/foo.conf -> /etc/ceph/ceph.conf
- rename /var/lib/ceph/*/foo-* -> /var/lib/ceph/*/ceph-* (this mainly
matters for non-osds, since the osd dirs will get dynamically created by
ceph-disk, but renaming will avoid leaving clutter behind)
- comment out the CLUSTER= line in /etc/{sysconfig,default}/ceph (if
you're on jewel)
- reboot
