Can you at least give us feature list being developed?
Some answers to questions like:
1. evacuating a vdev resulting in a smaller pool for all raid configs - ?
2. adding new vdev and rewriting all existing data to new larger
stripe - ?
3. expanding stripe width for raid-z1 and raid-z2 - ?
4. live conversion between different raid kinds on the same disk set - ?
No, you will not be able to change the number of disks in a raid-z set
(I think that answers questions 1-4). There is no plan to implement
this feature.
5. live data migration from one disk set to another - ?
Yes -- just add the new disk set, then remove the old disk set.
6. rewriting data in a dataset (not entire pool) after changing some
parameters like compression, encryption, ditto blocks, ... so it
will affect also already written data in a dataset. This should be
both pool wise and data set wise - ?
Yes.
7. de-fragmentation of a pool - ?
Yes.
8. anything else ?
