Hybrid pools

[AJV]

Are there any plans to support mix and matching for drives in a pool? Similar to how Synology has SHR which basically means we can upgrade the pool over time.

• Q: Can I change small drives our for larger ones to increase my storage pool's capacity?
  • A: Yes.  Drives can be exchanged one at a time to gradually copy all the data onto larger drives, Once all drives have been exchanged the pool's capacity will grow all at once.
    • Example: Lets say we have a pool with 6x10TB drives in RAIDz1, and we swap those out one by one for six 20TB units. When the last 20 TB drive has been installed, and the pool has finished re-silvering (copying data to a drive to re-construct the pool) then the pool's total capacity will jump from ~50TB usable to ~100TB usable!

You can mix and match drives but each drive will only utilize as much as the smallest drive. Would be nice to use the sections of larger drives though.
