October 12, 20223 yr Author Result: UUID: hidden Scrub started: Thu Oct 13 00:57:18 2022 Status: finished Duration: 0:09:33 Total to scrub: 412.41GiB Rate: 736.64MiB/s Error summary: no errors found
October 12, 20223 yr Community Expert Looks good for the moment, and now if one device fails pool should continue working, but of course should be fixed ASAP, also see here for better pool monitoring, you'll need to reset the current errors as explained there.
October 12, 20223 yr Author @JorgeB million thanksssss! I have already setup the monitor following the post provided. May you also provide guidance on swapping out the faulty cache drive? Besides, do you recommend do the upgrade of unraid first or swapping first? Thanks.
October 12, 20223 yr Community Expert Upgrade first since that functionally is broken on v6.9, then see here: https://forums.unraid.net/topic/46802-faq-for-unraid-v6/?do=findComment&comment=480419
October 13, 20223 yr Author @JorgeB Unfortunately the monitor is raising errors not long after the scrub. Do I need to re-do all the steps in order to make sure the cache drives are in sync before swapping? Regarding the link you sent, can I do the following as I don't have enough ports: 1. Stop the array and shutdown 2. Swap the faulty ssd 3. Power Up 4. Assign the new device in the faulty's SSD slot? 5. Start the array 6. Wait for cache copying to complete Is this procedure okay? Thanks!

October 13, 20223 yr Community Expert It's the Intel SSD again, if that's the one you were going to replace you can go ahead, and the steps you mentioned above are correct.
October 13, 20223 yr Author Thanks I just swapped the disk. Should I actually upgrade first? Or it will be fine if I do the swapping then the upgrade?
October 13, 20223 yr Author Sorry I am a bit confused on the steps right now. I should start the array with both cache drive (the old one) perform an upgrade Confirm upgrade successful Swap cache drive as the steps I mentioned above rebuild the cache pool Is this correct?
October 13, 20223 yr Community Expert You can do the upgrade now and instead of rebooting power off and replace the SSD, then just check that it's on the new release after boot.
October 14, 20223 yr Author Thanks @JorgeB I did an upgrade and see I am on 6.11.1 now. I also replaced the SSD and built the pool without problem. Is there any final check needed? Thanks! uncrate-diagnostics-20221014-2142.zip Hopefully this will be the final diags.
October 14, 20223 yr Author Great thanks a million @JorgeB you have been really patient and helpful!!! Speechless thanks going through this with me!!!
