Here's what I want: I have a vmware server running on etch, hosting 4 VM's. I want these 4 VM's to be hosted in such a way, that should anything fail on 1 VM host, there is another providing seamless service. I want to do this with the 2 pc's I already have, each with 2 NIC's, and no other hardware.
My basic question - what's the best solution to accomplish this? Here's what I've looked at: drbd/HA (heartbeat) - allows you to raid1 a disk partition between 2 pc's over ethernet issues: in the default primary/secondary failover config, if primary fails, there is some period of time (even if only seconds), required for the secondary to become primary - I can only assume this would mean rebooting all the VM's. however - you can run drbd in a primary/primary config - this sounds like what I want. But it sounds like I need a clustering files system to do this like GFS. After countless hours researching this, I'm still not sure how to do it - do I need GFS? OCFS? NBD? Now drbd isn't really a cluster, it's just raid1-ing 2 pc's - this could be all I need. But - would a REAL cluster be a better solution? I believe a cluster could provide load balancing, or at least optimized use of all available hard disk heads. Although, if drbd needs GFS, then in fact, doesn't this become a real cluster? What would a clustering solution look like? which is the best filesystem to use - GFS/OCFS ? would drbd still be needed if GFS is used? Any ideas, experiences, help - greatly appreciated!
