Supposing that that will not happen, we still need to choose
an appropriate time for downtime, and let users know in advance.

Yes, I am planning to do so.

I think there will be no
problem with different geometries since RAID works on 
partition level... So in case our partitions are not exactly matching
with the new disk, we only have to make them a few megabytes bigger
on the new disk to be sure, and re-add to existing array.
