What is the best approach on this use case?


Following is my needs:

  1. two disks forming a zfs raid1
  2. third disk with ubuntu 16.04 server installed
  3. I’d create a few ldx containers in the zfs pool

Sure the above three is quite easy to do, but the following:
4) replace the disk in #2, install ubunt 16.04 or newer (this will happen from time to time)
5) the system uses all the ldx created in #3 after #4, and back to operation as before.

What’s the best approach to this? Thanks
