Hello - just got his error on my boot USB drive - I would appreciate some help in understanding what the 2 errors below mean. Thanks in advance.

The messages certainly mean that the system is having troubles reading the USB stick    Do you have a backup backup of the USB stick?   Are you using a USB2 port (prefered over US3 as they seem to be more reliable)?

 

You might want to plug the USB stick into a PC/Mac to check it can be read.    If you do not have a backup then try and make one at this point.    The ‘config’ folder and its contents are the important information as it contains your license key file and all your settings.    It might be a good idea to run the USB Creator tool to rewrite the USB stick contents and then copy the saved ‘config’ folder replacing the contente of the one the USB Creator tool puts on the USB stick.

Thanks.

 

Yes I created a backup now. The drive is working and showing green - 

 

Should I replace it or continue using it?

It is really up to you.    During normal use there is very little writing to the USB stick so it is probably fine, but keep an eye on it.    It is only when doing upgrades To Unraid that any significant number of writes occur.

 

There seem to be a significant number of people who have experienced a similar set of issues when doing the 6.7 upgrade.    It make me wonder whether there was subtle change at the Linux kernel level that have increased the chance of large writes not always succeeding.   However that is just some supposition as many (including myself) upgraded without any such problems.

Interesting. My error popped up a few weeks after the upgrade finished successfully, so not sure if its related to the upgrade. It actually popped up when I was trying to upgrade a plugin, not sure why none of the plugins or anything else are on the flash drive. so not sure if that was a coincidence.

 

I guess I will get/find a new one and get ready to replace.

If you decide to buy a new one as a replacement go for a USB2 drive rather than a USB3 ones.    As well as being cheaper a USB2 drive tends to be more reliable and Unraid gains no performance advantage from USB3 as it runs from RAM after initial boot.

Thanks - will do!
