As long as you are only serving NFS, this works REALLY well. I have used it a bunch of times.

On an N3400 active/active w/DOT 7.3.5.1P1:****
I need to move vol0 from aggr0 to aggr1 on node A (so I can nuke its aggr0).****
I’ve done this kind of thing on a single independent node – it’s fairly well-documented in the “Storage Management Guide”.****
Basically:****
Create a newvol0 on the destination aggregate of adequate size***
ndmpcopy /vol/vol0/etc over to newvol0****vol options newvol0 root****reboot****
But in this situation, there’s stuff on aggr1 I’d like to keep serving during this transition. I’d like it very much if I could use failover to do that.****
Is it possible to pull this off with a takeover/giveback?****
It seems it might be problematic what with the takeover node presumably using /vol/vol0 as the root vol and the other node booting up using /vol/newvol0 as the root vol. Would the giveback work OK?****
It seems there’s room here to really hose things up.****
Any advice?****
Anyone seen documentation on such a procedure?****
