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?

    But moving to the HDDs and back is pretty slow, because the cache drive contains many many small files. This is why I asked if it is possible to do it this way. Because then it would only be a ssd => ssd transfer.
