HI all - I started upgrading my DS218+ with two new 4TB drives on Friday. I replaced the first one, which repaired overnight... All fine. I replaced the second drive at lunchtime yesterday - It was still repairing last night. This morning, logging into DSM is taking almost 10 minutes... and everything is crawling. Do I just leave it alone for now? Can I force restart when the storage pool is being repaired?
You should leave it to finish. You should check, maybe you have mixed EFRX and EFAX drives.
