commit fe44f400a3116a158ab331a92a49a4ad8937170d Author: Ken Gaillot <kgaillot@redhat.com> Date: Wed May 24 15:32:02 2017 -0500 Fix: crmd: attribute write-out not needed with atomic attrd This is a scalability issue, as the write-out results in CIB notifications for each attribute/node combination, which can overwhelm the crmd and get it evicted from the cib as a slow IPC client. diff --git a/crmd/join_client.c b/crmd/join_client.c index 45104831b..baa7be00b 100644 --- a/crmd/join_client.c +++ b/crmd/join_client.c @@ -313,7 +313,13 @@ do_cl_join_finalize_respond(long long action, if (AM_I_DC == FALSE) { register_fsa_input_adv(cause, I_NOT_DC, NULL, A_NOTHING, TRUE, __FUNCTION__); +#if !HAVE_ATOMIC_ATTRD + /* Ask attrd to write all attributes to disk.
