If you updated using the GUI you can to Tools -> Update OS and look for the "restore" option, it will show the previous Unraid release installed, I'm just mentioning that because there's a lot of data corruption and you're using a Microserver Gen8 with VT-d enabled, and those are known to be affected by Linux kernel bug that affects all Unraid v6.10 releases except v6.10.3, causing data corruption.
