Progress Module
|
|
|
|
===============
|
|
|
|
|
|
|
|
The progress module is used to inform users about the recovery progress of PGs
|
|
|
|
(Placement Groups) that are affected by events such as (1) OSDs being marked
|
|
|
|
in or out and (2) ``pg_autoscaler`` trying to match the target PG number.
|
|
|
|
|
|
|
|
The ``ceph -s`` command returns something called " Global Recovery Progress",
|
|
|
|
which reports the overall recovery progress of PGs and is based on the number
|
|
|
|
of PGs that are in the ``active+clean`` state.
|
|
|
|
|
|
|

PG Recovery Event
|
|
|
|
-----------------
|
|
|
|
|
|
|
|
An event for each PG affected by recovery event can be shown in
|
|
|
|
`ceph progress` This is completely optional, and disabled by default
|
|
|
|
due to CPU overheard:
|
|
|
|
|
|
|
|
.. prompt:: bash #
|
|
|
|
|
|
|
|
ceph config set mgr mgr/progress/allow_pg_recovery_event true
|
