Hi all, this morning I woke up to this in my inbox:

 

Event: USB flash drive failureEvent: USB flash drive failure
Subject: Alert [FEEZFILESERV] - USB drive is not read-write
Description: USB_DISK (sda)
Importance: alert
 

I logged into the server and the flash drive is showing "green", and the server appears to be running fine (I remember reading somewhere that the entire OS loads into RAM so that makes sense).  I'm also not surprised the USB stick is failing since it's ages old and wasn't exactly a high quality one to begin with.  

 

So I ask:  What do I do at this point?  How do I go about replacing the USB drive?  I've attached diagnostic logs for more info for people smarter than me.  Thanks in advance everyone!

First thing to do is reboot.  The OS runs automated file system check on the flash drive during boot up.  

 

If that doesn't fix it, turn off the server and run the file system check in another computer (chkdsk).

 

If this still happens, replace the flash drive https://wiki.unraid.net/Manual/Changing_The_Flash_Device

 

(An "unclean" parity check will result because the flag won't be able to be written to the flash when rebooting the system)
