January 16, 20242 yr Greetings! I'm totally new to unraid and linux in general. This homeserver is my first project with unraid. Today I got a new harddrive I want to use as the parity. Within the process of preparing for this, I defined another disk as Par2. So fine, so good. Today the new drive, (Ironwolf Pro+ 4TB), arrived. I stopped the array and set the Ironwolf als Par1, disabling Par2, since it should become an array-drive in the next step. Parity sync started with no problem, but estimated time is more than 3 days with a speed of ~ 10 to 12 MB/s. My setup: Server: Dell Wyse 5070, Intel Pentium Silver J5005 CPU @ 1.50GHz, 8GB DDR4 Fantech QB-35US3-6G: 4-bay HDD/SSD Box; connected with USB 3.2 Gen 1 to an USB SS+-Slot Drives: 1. Par1 = Seagate Ironwolf Pro+ 4TB 2. Dis1 = Seagate Baracuda 1TB 3. Dis2 = WD 1TB 4. unassigned (yet) = WD 1TB The three 1TB-disks are old disks from my previous desktop-pcs; one beeing extrcated from an external USB-case. May the CPU be the bottleneck-factor? Most of the time, the 4 cores shift between 30 and 70%. But sometimes one of the cores hit the 100%... Any suggestion would be helpful, but please keep in mind that I'm pretty unexperienced in this field, so please explain it in small steps =D EDIT: Problem was the same, when I left the Par2 in place without unassigning it. Same "speed" and time for the parity-sync. unsc-gatekeeper-diagnostics-20240116-1300.zip Edited January 16, 20242 yr by Carmino
January 16, 20242 yr Nothing obvious logged, could be a slow disk, or a disk with slow sections, you can run the diskspeed docker. P.S. Pool needs to be scrubbed.
January 16, 20242 yr Author 1. DiskSpeed isn't really useful. Tried that another day when trying to find the bottleneck of slow speed when transfering data from my desktop to a shared folder. There it seems to be the CPU beeing the limiting factor. Problem is here, that diskspeed only shows a blank page when I hit the "benchmark drives" button. See screenshot. 2. Thanks for the additional hint... but what does that mean? 😅
January 16, 20242 yr Hello Carmino and welcome to the UNRAID forums! What are you planning to use your set up for? Have a look at the HDD SMART settings on your two 1TB drives. Drive properties>Self Test>SMART extended self-test: > START I wouldn't think there's any issues with the new4TB drive. But do a SMART short self-test: on that one.. Then, Run Settings>Fix Common Problems, and see whether anything comes up on that. It's a good idea to schedule this to run too.. (I use Daily).
