For what it's worth, I had the same errors on a rpi3 a few months ago, and eventualy gave up "to sort it tomorrow" - it hasn't been powered on since, but I still want to get it working. The system would run fine, but give the vfs errors on the 128GB usb thumb drive every week - like clockwork, when one of the heavier periodic jobs ran. I was running the latest CURRENT at the time. The thumb drive works fine elsewhere, and indeed - did on the same hardware when I test installed a linux install, and thrashed the hell out of it. I'll fire it up again - hopefully I'll still have the same results, and with 2 of us, we may find the cause quicker. (n.b. i never had swap errors, but I can't recall if i ever configured swap on the usb drive) Cheers, Jamie
