I replaced all the drives (including failing flash drive) and did a fresh install of unraid and it's still not allowing me to stop the array or run parity checks after several hours. Is this the best way to downgrade?: https://docs.unraid.net/unraid-os/manual/troubleshooting/#manually-upgrading-or-downgrading-an-unraid-release Is it possible it's just a USB or SATA controller failing? Maybe I should plug flash drive into a USB 2.0 port to see if that helps? The flash drive is still accessible / writable when I can't run parity checks. I'm not sure downgrading would help since this started without upgrading the OS or anything. server01-diagnostics-20240107-0007.zip

Ran 10 passes with Memtest and it passed What other hardware issue could it be and how would I test for it? Server seems to run other than parity syncing and smb shares.

Started off with parity sync finishing instantly and unraid not shutting down / smb shares not working (knew something was wrong) so I removed a drive to see if maybe that was the cause. It was not. Ran a test on the flash drive and it failed. Performed backup via webUI and restored backup to new flash drive and transferred the license. I put the drive I took out back in and tried to do a sync but it seems to do nothing. On the latest stable version. Attached are the logs after trying to run sync multiple times. Update: Just used usb tool to make fresh build on flash drive and copied over config folder and it's still not working. server01-diagnostics-20231228-1352.zip
