Description

osd_fast_shutdown_notify_mon option is false by default. So users suffer
from error log flood, slow ops, and the long I/O timeouts on voluntary OS
shutdown before they are aware of the existence of this option.

This option was introduced in https://github.com/ceph/ceph/pull/38909, but was set false by default. There is a lot of evidence at this point to show the usefulness of this setting, so enable it by default. More details in https://github.com/ceph/ceph/pull/38909 and [ceph-users] OSD spend too much time on "waiting for readable" -> slow ops -> laggy pg -> rgw stop -> worst case osd restart.
