Error ENOTSUP: Module 'pg_autoscaler' is not enabled (required by command 'osd pool autoscale-status'): use `ceph mgr module enable pg_autoscaler` to enable it

使能pg_autoscaler:

ceph mgr module enable pg_autoscaler

查看PG自动伸缩状态:

 

设置PG自动伸缩:(ceph osd pool set pool_name pg_autoscale_mode on)

设置目标ratio:

ceph osd pool set volumes target_size_ratio .8 

查看是否开启:
