I reconfigured my server and am trying to rebuild parity. The parity check starts off and then at some point, hits read errors on disk 4: At that point the parity check seems to freeze as the reads and writes no longer increment and the progress on the Array Operation tab stops. Another weird behavior is that I cannot pause or cancel the parity check at this point. Clicking either button seams to do nothing and I cannot stop the array. The only thing I can do to stop it is to reboot the whole server. Interestingly, I can navigate to all other aspects of the server and even assemble the diagnostics, which I have attached. One other data point, the data on disk 4 seems to be the issue as this is the 3rd different drive it has caused read errors on. I have also moved the drive to different slots in the Unraid server and to different physical cables in the physical box. Is there any way to tell which files are causing the issue so I can avoid losing all 4 TB of data? I will wait to reboot the server until anyone has any suggestions, thanks in advance metroplex-diagnostics-20221111-2042.zip

Please forgive this potentially dumb question, but it's about multiple printers and cameras. If I have 2 printers, each with a USB cam, can I plug all 4 USN cables into a powered USB hub and plug that into my unRAID server to get them all connected to it?

WTF? I powered down, checked connections, started back up and suddenly have 4 drives saying they are unmountable with no file system! Trying to run another diagnostic but it's taking forever.

Thanks for the quick response. I don't think I have a power problem, what would be the best way for me to test that? I'll look at the server and see if any drives are loose. ~Conan

Greetings! I have been running UnRaid for a couple years now but still don't know that much about it. I recently lost one of my parity drives and one of the data drives, so I set about replacing them. I have a total of 2 Parity drives, both 6TB and 14 data drives, varying from 2TB to 6TB, all in a rackmount server case. I'm running a Supermicro X8DT3 version 2.0 board I through in a replacement drive for my parity, but it is not showing up in the unassigned devices at all. I thought maybe I got a DOA drive so I swapped it for another new drive with the same result. I also swapped it to a different slot and different cable to make sure it wasn't the cable. I also notice that my log is at 100% and am not sure how to clear it. I've included that here too. I appreciate the help, let me know what other info I can give to facilitate this. ~Conan metroplex-diagnostics-20200907-2207.zip metroplex-syslog-20200908-0217.zip
