Question about HA + OpenVZ + DRBD + LVM on 1.4 Storage Model

[bogomolov]

Hi all (1st post

Its possible to use drbd (primary-primary) with lvm on top, with each lv containing one vps (OpenVZ), using a common FS (ext3, jfs, ...) on the new storage model for HA purposes?

My idea is something like that:

[FONT=Courier New]    ::node01::                      ::node02::

  {vps01}{vps03}                  {vps02}{vps04}
  [LV_01][LV_03]                  [LV_02][LV_04]
     [LVM_VG]                        [LVM_VG]
     [LVM_PV]                        [LVM_PV]
      [DRBD]  ---primary//primary---  [DRBD]
    (/dev/sdb1)                     (/dev/sdb1)
[/FONT]

Each node runs a different vps from another, but all vps´s are sync via LVM lv´s on top of DRBD primary/primary. In case of fault of some node, the left node just nid check integrity of vps fs and startup him.

PS: Sorry my bad "engrish"

sure, see http://pve.proxmox.com/wiki/DRBD

but HA is not implemented yet.

I will try this on next weeks with heartbeat to see how all works...

Interesting solution. Did you get this up and running?
