Re: [ceph-users] [ Ceph MDS MON Config Variables ] Failover Delay issue

Hi Team, I was setting up the ceph cluster with - Node Details:3 Mon,2 MDS, 2 Mgr, 2 RGW - Deployment Type: Active Standby - Testing Mode: Failover of MDS Node - Setup : Octopus (15.2.7) - OS: centos 8.3 - hardware: HP - Ram: 128 GB on each Node - OSD: 2 ( 1 tb each) - Operation: Normal I/O with mkdir on every 1 second. T*est Case: Power-off any active MDS Node for failover to happen* *Observation:* We have observed that whenever an active MDS Node is down it takes around* 40 seconds* to activate the standby MDS Node. on further checking the logs for the new-handover MDS Node we have seen delay on the basis of following inputs: 1. 10 second delay after which Mon calls for new Monitor election 1. [log] 0 log_channel(cluster) log [INF] : mon.cephnode1 calling monitor election
