Shared LVM (FC) - HA if full multipath outage occurs

[gbonev]

Greetings,

We created POC with 2 Hypervisors and witness qdevice.
HA works as expected when pulling the plug on single HV.

Since we have decent DELL EMC / VPLEX - we decided to use shared FC with storage type LVM in order to be able to demonstrate HA.

I am trying to figure out if there is way to make Proxmox aware when one of the Hypervisors has completely lost multipath (but is still UP) - if there is way to make the VMs (re)start on the healthy Hypervisor where the multipath has no issues.

Thanks for any hints

That is a good question and I don't know the answer.

What is your use case for the FC problems on one host? We use multiple FC-HBAs and multiple switches so that this is very, very unlikely to happen.
