They are still supported (and will continue to be supported for the foreseeable future). Thanks, Ilya

CephFS doesn't write synchronously even if CEPH_OSDMAP_NEARFULL is used, then should fixed by CEPH_POOL_FLAG_NEARFULL.

I'm not sure I follow. - if (ceph_osdmap_flag(&fsc->client->osdc, CEPH_OSDMAP_NEARFULL)) + if (pool_flag(&fsc->client->osdc, ci->i_layout.pool_id, + CEPH_POOL_FLAG_NEARFULL)) AFAICT this change would effectively disable this branch for pre-mimic clusters. Are you saying this branch is already broken? Thanks, Ilya

And in Luminous version, this flag is cleared as a legacy and has no effect too.

Well, it appeared in mimic in v13.0.1 and was backported to luminous in v12.2.2.

What about this code in OSDMonitor::tick() that showed up in kraken in v11.0.1 and was backported to jewel in v10.2.4? if (!mon->pgmon()->pg_map.nearfull_osds.empty()) { ... add_flag(CEPH_OSDMAP_NEARFULL); } else if (osdmap.test_flag(CEPH_OSDMAP_NEARFULL)){ ... remove_flag(CEPH_OSDMAP_NEARFULL); } if (pending_inc.new_flags != -1 && (pending_inc.new_flags ^ osdmap.flags) & (CEPH_OSDMAP_FULL | CEPH_OSDMAP_NEARFULL)) { ... do_propose = true; It's there in v10.2.11 (the final jewel release). It's also there in hammer since v0.94.10... Thanks, Ilya
