Something is very wrong with my system. I am using five: 8TB 5400 rpm HDDs they are now installed in two backplanes with 4 SATA slots in a Silverstone C381 case. Using a Silverstone branded: Mini-SAS HD SFF8643 cable this then connects to a Lsi/broadcom SAS 9300-8i Host Bus Adapter, that is inserted in a Asrock Rack X470D4U motherboard pcie slot. My CPU is a 3700x and i am running a single stick of 16 GB ECC (unregistered), set to auto (ECC on) . (want to run more then 1 ram stick, but it hasn't been delivered yet). The system has had issues previously including Unraid reporting 8.900.000 errors on the parity drive. No important data is stored on the system. I'm just starting out with new hardware and am new to Unraid. Have had multiple XFS corruptions so far. I suspect one of my new devices is broken but i don't know how to narrow this down properly. tower-diagnostics-20191202-1526.zip

Thank you for your response! Yes it was listed as WD_My_ Book ..... . For future reference is it possible to ''explain'', to Unraid that it is the same device? I did run the xfs_repair and it does mount. Still a little skeptical about trusting this system with my data i previously had 8.900.000 errors on the parity drive all confined to a certain moment in time. All 5 drived are now hooked up to 1 of the backplanes in a Silverstone C381 case. Ussing a Silverstone branded: Mini-SAS HD SFF8643 cable this then connects to a Lsi/broadcom SAS 9300-8i Host Bus Adapter, that is inserted in a Asrock Rack X470D4U motherboard pcie slot. If i have a faulty component, then i don't really know how to narrow it down to which one. Are there any recommended tests? I did run pre-clears on the discs.

So i am new to Unraid. I have had dozens of issues so far, the latest one i that i moved a hard drive that was part of the array from a external USB enclosure to an internal bay. Now i had hope that Unraid was smart enough to figure this out automatically and just recognize the disc. It wasn't, i imagine there is perhaps some way too manually intervene and get Unraid to recognize the disc under its new name. But it was getting late and i just wanted to go to bed, so i set it to rebuild. This setup is completely new and stores no vital data (only test files), so its not like i could lose anything. After it completed the rebuild with zero errors it was now reporting So i rebooted the server and now it reports: Kinda strange because it also reports the disc as having the xfs file system. And it won't even mount in unassigned devices. This is not the first time i had problems i had to format a drive 2 times after a pre-clear, before Unraid was willing to mount it. Now suddenly while i was typing this is, Unraid decided that: I assume this is just a delayed reaction, to me i putting it back in the array, after seeing if Unassigned Devices could mount it. After starting the array it reports: Again. What is going on here? Edit: I checked the disc log. Forgot that was a thing you could click on, still getting used to this OS, see image: Edit 2: xfs_repair -n :
