I'm not certain exactly but this is in the depths of our common daemon startup/init code and from the name I assume it's about whether we're allowed to start threads running yet. ;) That's not something you can really change, although maybe we should move it out of a structure that's quite so user-visible. > > What does this do? > > - leveldb_compression: false (default: true) > - leveldb_block/cache/write_buffer_size (all bigger than default) I take it you're running these commands on a monitor (from I think the Dumpling timeframe, or maybe even Firefly)? These are hitting specific settings in LevelDB which we tune differently for the monitor and OSD, but which were shared config options in older releases. They have their own settings in newer code. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
