A flag called + `pglog_hardlimit` has been introduced, which is off by default. Enabling + this flag will limit the length of the pg log. In order to enable + that, the flag must be set by running `ceph osd set pglog_hardlimit` + after completely upgrading to 13.2.2. Once the cluster has this flag + set, the length of the pg log will be capped by a hard limit. Once set, + this flag *must not* be unset anymore. In luminous, this feature was + introduced in 12.2.11. Users who are running 12.2.11, and want to + continue to use this feauture, should upgrade to 13.2.5 or later. -- 2.39.5
