GitHub user baltazorbest closed a discussion: KVM HA feature too slow
Hey! I have the Cloudstack version 4.19.1.3 with 3 management hosts and 5 compute kvm nodes. I need to figure out how to enable HA in my infrastructure. My primary and secondary storages are NFS. I enabled HA on KVM hosts and set kvm provider KVMHAProvider. Then I created the compute offering with HA feature and a few instances with HA offering. After that I turned off one kvm host (to simulate sudden power cable unplug) and expected that the server would change its status to ‘down’ soon but it happened roughly 30 minutes later. I changed several global settings and restarted cloudstack-management one by one but it didn’t help. The changes were: - alert.warm: 1800 -> 120 - ping.interval: 60 -> 10 - kvm.ha.degraded.max.period: 300 -> 120 What should I do to force the ‘failed’ host to change its status to ‘down’ after 2 or 3 minutes and make the instances from this host to start on other hosts? Thank you in advance. GitHub link: https://github.com/apache/cloudstack/discussions/10097 ---- This is an automatically sent email for users@cloudstack.apache.org.
