November 6, 20223 yr Typical way to change disks in your cache drive (single or pool) has been to: 1. Disable VM 2. disable docker 3. change all shares to cache=yes 4. invoke mover, wait for it to finish 5. change drives However this is a little painful and slow. I was wondering if it was faster to just all the 2 new drives as additional drives to the cache pool, then when it’s done setting up, remove the 2 original drives. I then found this comment which indicates it’s possible: However my old drives are 512GB SSD and my new ones are 1TB. Will this work while ultimately leasing me using the full 1TB when the two 512GB are removed from the pool? Edited November 7, 20223 yr by tmchow

But the meat of what I'm asking is whether all that is necessary or if I can just add the 2 new 1TB drives to the cache pool, wait unitl they are added, then remove the other original 2 x 512GB, and in the end have a 1 TB cache pool
