All the files show up under /root as they normally would, and df -h shows sda1 mounted as overlay, but it boots into "Your JFFS2-partition seems full and overlayfs is mounted read-only". The 16gb usb only has has ~1gb on it. If i boot with the usb not plugged in, and then plug it in i can access and edit content, but some reads/writes are REALLY slow...like one time a directory with like 5 files in it took almost 30 seconds to ls -lah. Adding correct fstab to /etc/config or /tmp/mountd/.../upper/etc/config and rebooting did not change anything.

Suspecting that the issue is the usb is about to die, and the inconsistent read/write performance being the cause (also slow when using an ubuntu box to make a backup). Either

A) what else do i need to try/outputs you want (and boot method no usb, with usb, firmware recovery mode over usb serial)
B) would the correct method to switch usb sticks be to follow https://docs.onion.io/omega2-docs/boot-from-external-storage.html on new usb, copy fstab off new usb, restore image of current usb to new usb, move fstab into new usb

@josh-hightower if you post the output of df -hT that would help.

@josh-hightower :

You would want to check the same /dev/sda1 being mounted at two mount-points:
1:
/dev/sda1 ext4 14.6G 939.1M 12.9G 7% /overlay
2:
/dev/sda1 ext4 14.6G 939.1M 12.9G 7% /tmp/run/mountd/sda1

Thanks..

@josh-hightower :
I don't think you can mount an ext4 file-system in more than one place. Doing so would corrupt the metadata.

Does your application require that you mount a volume at /tmp/run/mountd/sda1 ?

Thanks..

@tjoseph1 everything uses paths relative to home. The second mount (/tmp/run/mountd/sda1) is just the automatic one, not manual. But if that were a problem, why would it be in the onion docs?

Could you point me to the onion docs.. May be the docs was presenting a special case ? I would like to have a look. Please post the link to the doc..

@josh-hightower :
You are right. I saw the df -h command output towards the end of the docs matches the screenshot you provided. May be things were different with b200 firmware, that you have.

# df -h shows only two lines pertaining to the sda volume (4.0G) in b233, which are:
Filesystem Type Size Used Available Use% Mounted on
..
/dev/sda1 ext4 4.0G 597.2M 3.2G 16% /overlay
overlayfs:/overlay overlay 4.0G 597.2M 3.2G 16% /

@josh-hightower :

Since this is an Omega2+ module, can you upgrade to b233 firmware, unless your custom app may have old version dependencies..

@tjoseph1 it uses oled, relay, 1 wire sensor, and then everything else if python libs so shouldn't be an issue there. I would assume that the functionality of some of the add ons (like relay) are not being removed even tho the hardware is being stopped? I have not verified it since code changes have been made since the last hardware swap, but the following is in my install script. I know python 2 is at EOL, but i have not migrated the project to python 3 yet.

opkg update
opkg install python pyOledExp pyRelayExp python-pip
pip insstall pyowm

@josh-hightower :
I am not familiar with b200 and it's overlay. I started 3 mo back with b233. Typically a volume is mounted at only one place. If you have another device, you could check the compatibility under b233, before migrating to b233.

@tjoseph1 long story short, that flash drive was failing...well more like failed. Forensic images have been taken merged with /overlay and just mounted and other and is a future project to test recovery or repair (have not looked at drive's board yet). Brand new flash drive (usb 3.0 even tho im pretty sure 2+ only supports usb 2) different 2+ and it is running fine. Also forced me to finish the update to my thermostat code to be able to push it to the different 2+. Even with this new drive that is working with 3199, could not get 1AB5 (one referenced to begin with) or my pro to correctly boot off it. Came across this, https://github.com/Pi4IoT/Omega2_External_Storage, which changes 2 flags...have not dug into it but it is mostly the same as the onion docs and it is working. Maybe that has to do with why the other 2 would not boot off it, they just booted and then mounted it. Never saw mtdblock6/7 before, wondering if the new firmware means that page (https://docs.onion.io/omega2-docs/boot-from-external-storage.html) is a little out of date?
