## SCENARIO 4: USE A DIRECTORY INSTEAD OF A DISK FOR OSD
# NOTE (leseb): we do not check the filesystem underneath the directory
# so it is really up to you to configure this properly.
# Declaring more than one directory on the same filesystem will confuse Ceph.

# since Ansible will sequential process the loop
