I have a small LXC running pi-hole. That was working.
But it not longer starts at boot and will not start from the web UI
It gives no error in the UI, task log says:

Code:
Requesting HA start for CT 103

From the shell.
root@proxmox # pct start 103 --debug
Requesting HA start for CT 103
root@proxmox #
^^this fails
But if I start it using:
root@proxmox # lxc-start -n 103

It works fine and shows up in the UI?

Any ideas?

Running 8.4.1 all updates applied. Running ZFS. Have also rebooted the host.
VMs on this host are fine too.

Have you checked for new task logs at the bottom after calling that?

If the guest is configured as HA, a start will request the start or shutdown/stop from the HA stack. That's why you see the log you see. A few seconds later you should see the actual start task triggered by HA.

If that is not working, what state is HA in? ha-manager status, and you can temporarily also remove that guest from HA.

Ahh yes that was the issue.
HA was down on one of the nodes. Also the source host had vmbr1 configured for the LXC... Destination only had vmbr0.
Too many NICs. I guess it needs the same interface available on all hosts?

Thanks for your help

yep, if you want to use HA you should make sure that all the resources needed for the guest are available on the nodes. If you do have differences that cannnot be aligned, you can make use of the HA groups and select the nodes that work and enable the "restricted" option. But you should have at least 2 nodes on which the guest can run, otherwise HA doesn't really make much sense ;)
