When I tried to upgrade from 7.6 to 7.7, I noticed that there was no free space.
Example:
Code: Select all

There are no user files. It looks like the "invisible" part of the disk is full. Most likely (possibly) - some temporary files that are hidden from the user.
Everything is fixed quite simply - /system reset-configuration no-defaults=yes skip-backup=y
Or in general - netinstall.
Followed by entering text commands from the backup.
This is not very convenient, because. you need to go to the objects and connect manually with a laptop to each device.
A possible cause of this problem could be a power failure.
It is strange, that the firmware update procedure does not clear this "hidden" area from "extra" files. For example, "normal" devices after upgrading to 7.7 have about 11% free space.
I have cAP ac which have 8%, 7% etc. free space.
