Does anybody else get the file system randomly disappear on the Omega1? I have the root running on a usb through a hub. I First thought it was a loos connection but this has happened in exactly the same way on two completely different devices. here is the error I get:

BusyBox v1.23.2 (2016-07-08 19:27:03 UTC) built-in shell (ash)

root@Omega-1E48:/#
root@Omega-1E48:/#

any ls after that returns a blank prompt. Also if I ftp into the device, it appears to be blank.

I would like to get to the bottom of the cause and also write a script that would detect this and rectify it if it happens. Currently I reboot and this fixes the problem. Any ideas on how to rectify without a reboot?

Thanks.

I'm not familiar with OpenWRT, but maybe there's a less drastic solution like unmount and remount the USB fs instead of rebooting? Is this something that you tried in your investigation about this problem?
