Hi Paul
Thanks for the response. I think I am not understanding how it was meant to work then. My understanding was that the manager used ipmitool to just keep querying the compute nodes as to their status so I assumed it didn't matter how you shut the node down, once it was down the manager would get no response and mark it as down (which it does). I am in testing mode so I think I will just go and pull the power and see what happens :) Thanks Jon ________________________________ From: Paul Angus <paul.an...@shapeblue.com> Sent: 12 March 2018 15:31 To: users@cloudstack.apache.org Subject: RE: KVM HostHA Hi Jon, I think that what you guys are finding, is that a controlled host shutdown, which will cause the agent to shutdown cleanly; Is not considered an HA event. I wouldn't expect CloudStack to take any action if you shut down a host, only if the host (agent) stops responding.

I have one manager node and 2 compute nodes running 4.11 with ipmi working correctly. >From the UI under HA - HA Enabled Yes HA State Available HA Provider kvmhaprovider although interestingly from the "Details" tab it shows - HA enabled No which I assume is a cosmetic issue ? On each compute node I have one HA enabled VM and one non HA enabled VM. I power off a compute node and the UI updates the host status and the VMs on that node stop responding but they never fail over to the other node. Couple of things I noticed - 1) as soon as i power off the compute node the HA state on the other node shows "Ineligible" 2) In the UI the instances all still show as green even though two of them are not available Any help much appreciated ________________________________ From: victor <vic...@ihnetworks.com> Sent: 07 March 2018 17:01 To: users@cloudstack.apache.org Subject: KVM HostHA Hello Guys, I have installed cloudstack 4.11. I have enabled HA for each hosts I have added. I have also added ipmi successfully (using ipmi driver). The hosts are showing like the following. ======= HA Enabled Yes HA State Available HA Provider kvmhaprovider ====== Also the host is showing the following correctly Resource state --> Enabled State --> UP Power state --> On So I have shutdown one of the hosts to see how the KVM hosts Ha is working. I have waited for half an hour. But nothing has happened. What will happen to the VM's in that host, if the host failed to back up. There isn't much from logs. Regards Victor
