Basically after openwrt 19.07 upgrade from 18.04 I lost my USB external HDD drive partition files.
I've updated, only that settings have not been saved, I've uploaded the configuration backup that just created before updating. Nothing, so decided to start configure again done in the following order: adblock, transmission, configured extroot/overlay, rebooted. So I woke up with 2 folders: torrents and download, both of which are attributed to transmission. The rest of the folders are gone. Installed samba4 version to see my shares, but nothing to see anymore.
Any idea how can I rescue my files? The files are there as my free space shows
