RDM (Raw Device Mappings)

[bandzior]

Hello.

In my lab i have installed Proxmox 3.4. I have three servers connected to storage array through SAN network (FC). My VMs are on LVM on the array.

I use virtio driver to connect LUNs from storage array directly to VMs. The problem is that i have to reboot the linux (Debian 8) VM to see new disks.

My VM config file is:

bootdisk: scsi0
cores: 4
hotplug: 1
ide2: local:iso/debian-8.0.0-amd64-DVD-1.iso,media=cdrom
memory: 1120
name: deb8
numa: 0
ostype: l26
scsi0: lvm:vm-102-disk-1,size=120G
scsi2: lvm:vm-102-disk-2,size=32G
scsi3: lvm:vm-102-disk-3,size=60G
virtio0: /dev/disk/by-id/dm-uuid-mpath-360060e80101d4f70058bd4c70000002c,media=disk,cache=directsync
smbios1: uuid=fe87cccd-63e8-4c68-8778-cf2tg7667f89
sockets: 2

how do you add the disk (virtio0?) to the vm ?

With CLI/SSH and WebUI.

Ok, it was just to be sure than it was not by editing the vmid.conf directly.

do you have theses 2 modules loaded in your guest ? :

acpiphp
pci_hotplug

IMHO, in Debian 8 i don't have to load these modules because there are compiled into kernel.
