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....

Hi Sebastian, I think you should split the volume into LVM partitions and then run a DRBD device for each partition. I run this config, RaidArray -> LVM -> DRBD8 -> Xen and it works well. You need the independence of one drbd device per VM otherwise things are difficult. You may also want to ask xen-users -at- antibozo.net for their DRBD script, on my Centos Xen 3.30 setup it works much better, it also avoids the need for IMHO dangerous dual primary config. I synch multiple arrays with multiple DRBD devices at once. DRBD equally shares the array write bandwidth between DRBD devices. My Raid1 arrays manage 80Mb/second each write speed, 2 DRBD devices synching at once on each of the 3 arrays yields 40mb.sec per DRBD device which totals a perfect 240Mb/sec synch rate (I used Infiniband to link the two DRBD servers together so am not bound by the bandwidth constraints of GB Ethernet).

You should be referencing the DRB device in the Xen config file, not the
physical device. If you setup the DRBD device shown below then you would
reference "/dev/drbd1" in the Xen config file.
