Hey,

I have a SSD pool with two relative small SSDs:

Now I started to notice that one of my SSDs started to fail. So I thought, why not use this opportunity to upgrade the pool. This is how I expect it to work:

  1. Buy two new bigger SSDs
  2. Restart server in safe mode
  3. Remove failing SSD
  4. Install one of the new SSDs
  5. Add the new SSD to the pool
  6. Start the Array?
  7. The pool should regenerate???
  8. Start with Step 3 again and replace the second small SSD
  9. Profit ???

Is this how it works or do I really first need to use the mover and move all data back to the hard drives and replace the pool all at once?

    You could use this opportunity to upgrade your cache pool and use ZFS in one step:

    • Install two new SSDs
    • configure new second cache pool with zfs
    • stop all containers and VMs
    • run mover
    • switch all shares from old to new cache pool
    • copy all data remaining data from old to new cache pool
    • start containers and VMs
