(Searched forum, didn't find much. I am at least passingly familiar w/ the extroot entry on the OpenWRT Wiki)
I have a 1G USB flash stick inserted (TP-Link TL-WDR3600 v1), did the unmount/format with adding it as extroot. (And a percentage as swap, but not really relevant). Tried this on both production 1.8.1 and after a fresh upgrade to 1.9.1, default settings.
Drive is indeed formatted, /dev/sda1 however is mounted to /tmp/usb_mount/043f0ea6-01 (I assume a semi-random GUID).
"df -h" shows /rootfs (/) and /overlay (/dev/mtdblock3) is only 768k (320k free atm, but that will rapidly disappear)
How do I tell if the overlay is actually using the external flash storage or just internal flash/nand/whatever?
Ultimate goal is to either just use the whole of /dev/sda1 as the overlay, or in lieu of that, Increase /overlay size at least a few hundred k and reliably/automatically mount the rest of the drive (okay if it's another partition) to something like /mnt/USB1/
Any help/pointing to existing posts/documentation appreciated!
Edit: Conflated overlay w/ extroot
[Solved?]Adjust overlay size? (Also gargoyle mount settings)

Re: [Solved?]Adjust overlay size? (Also gargoyle mount setti
(This should probably have been in the troubleshooting section, sorry.)
To answer my own "How to check for Extroot", (besides seeing size reflected in / and /overlay) when working it shows up in the USB Storage page. "External root detected on /dev/sda1."
My /etc/config/fstab had the following:
Changing option target to '/overlay', and both enabled to '1' and rebooting, worked for enabling both the extroot and swap. (This might be a bug in the "Format disk, enable swap, and Use disk as external root" section.)

My /etc/config/fstab had the following:
Code: Select all
config 'mount'
option target '/mnt/sda1'
option uuid 'fa4821f9-09af-4327-a53a-ce1487a0b195'
option enabled '0'

option device '/dev/sda2'
