Some questions. . .
- I have a DS14 shelf with 36gb disks, and FC8 shelf's with 18gb
disks. Each shelf has a HotSpare. If a 18gb disk fails will it for sure use the 18gb hotspare or is there a chance it will pickup the 36gb hotspare?
It will use the 18g hot spare.
- I'm thinking about migrating all the data on the 36gb drives
(including /etc folder) to fewer 72gb drives. What's the best way to do that? Can I add the new 72gb disks to the volume with 36gb drives, then start to remove 36gb drives over time?
No. You need to build a new volume and copy. This need not cause as much downtime as you think because you can copy over a snapshot with ndmpcopy while leaving the filer up. When that is done, make another snapshot and do an incremental copy to pick up the changes that happened during the big copy. Then kick everyone off the filer, take a final snapshot, and do a final incremental copy to pick up the last changes. Your downtime should be pretty minimal.
