[PVE-User] Proxmox, iSCSI, Mirrored LVM?

Hello, has anyone tried LVM mirror for storage HA?
We managed to get mirror running with two iSCSI disks, but when one of
devices goes offline, test VM acting strange.
Sometimes it _may_ work after one disk failure and connection recovery,
but more common result is VM going to zombie state.
In that case, i cannot even kill process, it continues to work in Zl
state even after sigterm, and the only way to kill that VM (and restart
it as well) is to reboot node (since it still holds descriptor and some
files like VMID.qmp. BTW, what is that "qmp" file?).
