I would really like fine granularity in migrating the resources using my drbd disks. Each resource is entirely contained in a directory. I have 4 phyiscal disks on each node backing drbd. I don't want to use pri/pri and GFS for this. One way to accomplish this would be to lvm all 4 disks using striping, then make several (at least two) drbds on top of several LVM logival volumes. Is there any reason I can't extend this idea beyond two drbds and use 24 drbds on top of 24 logical volumes, each with one directory (I have 24 directories). Half would be pri/sec on node one and half would be pri/sec on node two. This would let me migrate directories as needed. Is there any problem with this? What's the overhead of all those drbd worker processes? Also, is there any way to specify a global sync rate so that if only one drbd is syncing it'll take the full sync rate, but 6 or 7 drbds syncing will collectively share that same sync rate?
