[Xen-users] Disk support for live migration and mirroring
I have two systems on a the way to replace a ailing xen-2.0.7 box. They will be brought current with xen-3xx . The systems need to beable to have uptodate copys of all information in the event that one of the nodes fails. Allowing the DomU''s from the failed box to be started on the remaining box. A basic HA cluster. I figured I could use DRDB to mirror partitions and then export them via nfs and use heartbeat to move who is the active NFS server. But this would require me to use sparse files from disk images. Has anyone used anything similar? Its a simple set up, I do not have shared storage so i have to make due with DRDB or NBD+MD0 but im open to anything. Is there a better way given the hardware to provide this time of availability?
