## 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.

|
# Prepare means
|
|
# - create GPT partition
|
|
# - mark the partition with the ceph type uuid
|
|
# - create a file system
|
|
# - mark the fs as ready for ceph consumption
|
|
# - entire data disk is used (one big partition)
|
|
# - a new partition is added to the journal disk (so it can be easily shared)
|
|
#
|
|
|
|
# NOTE (leseb): the prepare process must be parallelized somehow...
|
|
# if you have 64 disks with 4TB each, this will take a while
|
|
# since Ansible will sequential process the loop
