Hi, Last time I tried this (like more than a year ago) this worked. Do you have IPMI (power management) credentials set for the hosts? Usually the Host HA undergoes multiple state transitions of concluding a host head, shoot the node in the head and finally restart the VMs on other host.
This also needs a few global settings enabled for the Host and instance HA. https://docs.cloudstack.apache.org/en/latest/adminguide/reliability.html#ha-enabled-hosts https://www.shapeblue.com/host-ha-for-kvm-hosts-in-cloudstack/ Thanks, Jayanth Get Outlook for Android<https://aka.ms/AAb9ysg> ________________________________ From: fa...@boccaciccio.it <fa...@boccaciccio.it> Sent: Friday, February 9, 2024 2:05:57 pm To: users@cloudstack.apache.org <users@cloudstack.apache.org> Subject: Cloudstack Host HA Hi all, I have a question about host HA. I have a cluster with KVM (QEMU emulator version 6.2.0) with NFS(v3) primary storage. I have dedicated 1 host in this cluster for HA but, when I tried to shutting down another host in order to test HA functionality, it stops with error: "Failed to get shared "write" lock Is another process using the image". Also, if I try to restart manually the VMs on any hosts, it fails with the same error. If I restart the hosts where the VMs were running, I'm able to start them back with no issues I made some investigation on this and found out this old issue (https://github.com/apache/cloudstack/pull/4567) which made me tought that this should be already sorted. What am I doing wrong? Thanks in advance, Br, F
