Hello, good afternoon.  I wanted to see if anyone else has run into this problem.  I am on Unraid 7 and have a pretty stable environment.  My uptimes can range from a month to 3-4 months until I need to do something that requires a reboot.  So no problems typically.  But today had a big moment of panic.  I have a windows VM and decided to mount a flash drive to it.  All good, plugged it in, changed VM settings, was able to start using it in Windows after unencrypting it.   A few min later, BOOM.  Everything down.  I check unraid console and see the dreaded "Your flash drive is corrupted or offline. Post your diagnostics in the forum for help."   I could view system logs but it was filled with errors trying to read the OS flash drive.  I could run diags but they failed to export.  I was pretty much unable to do almost anything except view pages.  I took some screenshots and rebooted and everything came up beautifully, minus a network setting I had previously changed that I had to modify again. 

 

Has anyone ran into this?  Is there a workaround?  I can surely just not do this, but I feel like that is a bad way to go about it.  I suppose this also has me wondering if I need to buy a flash drive to have on hand 'just in case'.  The current drive is several years old but hasn't shown any signs of failure.  Never had a single issue until this incident where I plugged in the other USB flash drive.

That suggests that using a flash drive with the VM interfered with the OS flash drive, possibly a config or USB controller issue.

It was weird that it took a couple of minutes, you would think it would have happened immediately.  The OS flash drive was plugged into the back of the system while this USB was plugged into the front.  It clearly did not like it but unsure of how to troubleshoot that within Unraid.  What configs would possibly cause that?

Sounds more like a USB problem, you enable the syslog server and post that if it happens again.

"If it happens again".. Well, I never have done it before and I mean, at this point, I don't want to plug in any USB storage device given how unraid responded.  But it shouldn't be that way.  The UPS plugged in through USB and the flash drive for the OS have been fine.  Is there not any other way to go about it?  I guess this is another reason I am not a big fan of the OS running from a flash drive, you should be able to plug in a storage device and copy files without something like that happening.

Without any logs difficult to say what the issue could have been, it would just be guessing, but it's certainly not normal.
