VMs are hanging after SAN failover

[ewuewu]

Hello Guys,

thank you very much for your absolutely great piece of software.

I’am testing proxmox connected to a failover capable iSCSI SAN (as LVM storage). We are running into little problem if we test the failover feature on the san box. If we start the failover on the san it takes approx. up to 1 second til the connection is back again.
Unfortunately all VMs are frozen afterwards.
Is there a way to make proxmox a bit more tolerant?

I did not see this recently, I assume you are using also multipath?

what OS do you run in your VM? also post the used settings ('qm config VMID')
