Auto update is failing on falco-release.. and I have been digging into the logs for this device.. 

There seem to be a ton of I/O errors during update on chromeos2-row4-rack4-host3:

Is it possible that the devices drive is failing? What other causes could this have?

Aviv do you have some advice on this?
