4. Available Volume space I believe that as part of the upgrade DOT has to go and change all of the inodes. Are there any implications as far as available space in a volume ? Do I need to make sure that I have some n% of free space ?

Yes the inodes are bigger, but I don't think it affects your usable space much, if at all. I think NetApp says we need to have 10% free space for the 7g OnTap upgrade.

The larger inodes (128 bytes => 192 bytes) came with 6.5.x (well, they were there in 6.5.1R1P6 when we went to that, anyway). They don't get any larger again with 7.x.

Larger inodes certainly doesn't affect disc space usage significantly. But if you are tight on RAM on the filer then it can make things that munge over lots of inodes (e.g. dump, quota on/off) have a worse effect on the cache.
