[GitHub] [cloudstack] weizhouapache opened a new issue #4211: VM HA does not work when server is stopped gracefully
weizhouapache opened a new issue #4211:
URL: https://github.com/apache/cloudstack/issues/4211
When we stop a server (hypervisor) gracefully, vms on it will NOT be started on other servers even HA is enabled.

For bugs, show exactly how to reproduce the problem, using a minimal test-case. Use Screenshots if accurate.
For new features, show how the feature would be used.
-->
<!-- Paste example playbooks or commands between quotes below -->
~~~
1. create a service offering with HA enabled
2. deploy a vm
3. go to the server where vm is running on, and stop it by "poweroff" command
~~~
<!-- You can also paste gist.github.com links for larger files -->
##### EXPECTED RESULTS
<!-- What did you expect to happen when running the steps above? -->
~~~
vm will be started on other servers.
~~~
##### ACTUAL RESULTS
<!-- What actually happened? -->
<!-- Paste verbatim command output between quotes below -->
~~~
vm is NOT started on other servers.
only when the server is Up again, cloudstack detects the vm is stopped out-of-band and starts it.

@GabrielBrascher we use nfs as zone-wide storage pool.

This doesn't sound familiar @weizhouapache . To recap,
- a hosts is HA enabled? (genuine question , here)
- a vm with a ha enabled offering is created on it.
- the server is powered off. Is by means of an remote (ipmi) action or by logging on to the console and issueing a halt command?
I would not expect this behaviour as a user but it might be a side effect of the host-ha, hence my questions.

hi @weizhouapache,
My environment is similar to yours, apart from the storage pool that I use cluster-wide, on this environment I could see HA working on cloudstack version `4.13.1.1` with an NFS cluster-wide storage pool.
On 4.13.1.1 version I could see my VMs migrate to a suitable HOST after I force shut down the HOST where those VMs were, but with gracefully shut down I couldn't see the HA working, those VMs never migrate to another suitable HOST, only when this HOST came back the cloudstack detected this VMs as stopped. But at `4.14` and `4.15` version, I couldn't see HA working even when I force shut down, those VMs are never detected as stopped by cloudstack

@DaanHoogland
1. do you mean OOBM based ha ? no, we do not use it.
2. all vms are ha-enabled.
if kvm cloudstack-agent is stopped, there is no thread in cloudstack to determine its actual host state.
