March 3, 20251 yr A month ago I had a similar issue where all of my disks were both active on the array but also showing up in the unassigned devices. I took some screen shots this time and I download the diagnostics.. this time the log seems to be more in tact than that last time. I rebooted and everything came back online with the exception of the Parity & Parity 2.. they show the RED X (disabled). Just like last time, this is happened at the beginning of the month towards the end of running the scheduled parity check, I don't know if is detecting errors and causing the issues or not. unraid-diagnostics-20250303-1320.zip
March 4, 20251 yr Community Expert Multiple disks dropped offline at the same time, looks more like a power/connection issues, also see issues with the flash drive, you should replace it.
March 4, 20251 yr Author Is there any reason why this would only be happening during a parity check or is there any other reason other than a power/connection issue that multiple disks drop offline? And thanks for the heads up on the USB.. I just replaced that USB maybe 6 months ago..

March 4, 20251 yr Author Solution well I went ahead and used the "New Config" option and I'm in the process of re-building the parity. I'll look into finding a new USB drive.. hopefully one that lasts.
