February 1, 20206 yr I recently upgraded one of my drives from a 3TB to an 8TB drive according to Unraid's documentation. When I went to start the parity rebuild, I saw that my speeds were absolutely awful (10-20 days estimated)! What's going on? pikachu-diagnostics-20200201-0705.zip
February 1, 20206 yr Community Expert There's something writing to disk1, stop all writes to the array and rebuild speed should increase by a lot. You should also upgrade to v6.8.2, and since the cache pool was just created on v6.7 it's not redundant because of this bug.
