ceph placement group状态有哪些

ceph placement groups (PGs) can be in one of several states, depending on the health of the underlying objects and the state of the cluster as a whole. The most common PG states are:

Active: All objects in the PG are healthy and accessible.

Clean: All objects in the PG are healthy, but some or all of them are not accessible (e.g., because they are located on a node that is down).

Degraded: Some objects in the PG are healthy and accessible, but others are not.

Recovering: The PG is in the process of recovering from a previous error state.

Backfilling: The PG is in the process of filling up objects that were previously not accessible.

Wait: The PG is waiting for some other action to complete before it can transition to another state.
