[Xen-users] drbd8 - lvm - xen

[Sebastian Igerl <sig@xxxxxxxxx>]

Hi,

What I'm trying to to is to set up 1 drbd active/active device then
split this with lvm creating about 20 volumes and then run xen on top of
that lvm volums !

I tried for days now and it isn't working... anyhow, do you see any
problems why this shouldn't work..

Should I create 20 drbd devices and use the drbd helper script for xen ?
isn't using so many drbd syncs a lot of overhead ? never tried it...


xen4 conf # xm create test1.cfg 
Using config file "./test1.cfg".
Error: Device 768 (vbd) could not be connected.
Device /dev/xen3and4/hd23 is mounted in the privileged domain,


This is what i'm getting right now.. 
/dev/xen3and4/hd23 isn't mounted...



xen4 conf # cat test1.cfg 

kernel = "/usr/lib64/xen/boot/hvmloader"
builder = "hvm"
device_model = "/usr/lib64/xen/bin/qemu-dm"
memory = "1024"
maxmem = 2048
maxmemory = 2048
name = "test1"

dhcp = "off"
vif = ["type=ioemu, mac=00:16:3e:00:00:20, bridge=xenbr0"]
#cpus = ""
#vcpus = 1 
disk = ["phy:/dev/xen3and4/hd23,ioemu:hda,w" ]

serial="pty"
boot="c"

vnc=1
vncviewer=0
keymap="de"
vfb = [ "type=vnc, vncpasswd=ssss, vnclisten=0.0.0.0, vncdisplay=23" ]
sdl=0



since i'm using lvm on top of drbd, xen should'nt be aware of drbd..
using only lvm it workd...

mouting   drbd-lvm2-device works too.... ( only on one site because i
haven't set up any cluster filesystems.. )



Thanks,

Sebastian
