This charm deploys a Ceph cluster.
|
|
|
|
It uses the new-style Ceph deployment as reverse-engineered from the
|
|
Chef cookbook at https://github.com/ceph/ceph-cookbooks
|
|
|
|
This charm is currently deliberately inflexible and potentially
|
|
destructive. It is designed to deploy on exactly three machines.
|
|
Each machine will run mon and osd.
|
|
|
|
The osds use so-called "OSD hotplugging". ceph-disk-prepare is used
|
|
to create the filesystems with a special GPT partition type. udev is
|
|
set up to mount such filesystems and start the osd daemons as their
|
|
storage becomes visible to the system (or after "udevadm trigger").
|
|
|
|
The Chef cookbook above performs some extra steps to generate an OSD
|
|
bootstrapping key and propagate it to the other nodes in the cluster.
|
|
Since all our OSDs run on nodes that also run mon, we don't need this
|
|
and did not implement it.
