Martin, Thanks for your input, and to all the folks who've added their two cents. I have successfully built and test 0.7.24, and can manually fail over as described on the DRBD website. I've RAIDed all my disks, including the meta-disk, and I'm very happy with the results I've seen so far. I'll move on to integrating it with Heartbeat2 next, but I don't anticipate any problems there. Again, thanks - this list has been very insightful and helpful. Best Regards, Ryan Martin Bene wrote: > Hi Ryan, > > >> Thank you for your input.
