Backport mon: add a cache layer over MonitorDBStore #5524
Last modified: 2017-07-30 11:21:43 EDT
Help to prevent spurious election behavior caused by poor leveldb performance which leads to slow OSD restarts.
Upstream tracker: http://tracker.ceph.com/issues/12638
Upstream PR: https://github.com/ceph/ceph/pull/5524
Fix will be in non-RHEL Ceph v0.80.8.5
Kefu, can you please tell us the steps to verify the bug fix.
Tamil, i am not sure if we have a way to verify the cache for the monstore. the cache layer speeds up the access to the leveldb. we don't leave traces/print extra message when we are accessing the leveldb directly without the cache, and no extra message is printed when we are using the cache.
