# 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)
