I recently updated to version 24.10.5 on my Xiaomi AX3000T and everything seems to be working fine except that the amount of disk space used is no longer displayed in the System/Software section.
Obviously, it's not a serious problem since it doesn't affect the router's operation.
What I see is: Disk space:
0% used (68.00 KiB used of 56.89 MiB, 56.83 MiB free)
and previously, with the earlier version, it showed around 64% used with the same packages installed.
That moves all installed packages from /overlay into /rom, freeing up all the space they previously took. Now the only thing in the overlay is probably /etc/config/*...
Numbers look correct: 68_000/56_890_000 = 0.001195289154508701, so that 0% is really 0.1% rounded...
I just updated all the packages that appeared as updatable (all related to Luci), and now it shows 1% usage (968.00 KiB used out of 56.89 MiB, 55.95 MiB free). Apparently, this version behaves a bit differently than the previous one, since the previous version, as I mentioned before, displayed different values ββand showed that much more space had been used. Anyway, the system seems to be working very well.
Upgrading packages (via the CLI opkg upgrade command or the LuCI Upgrade... button) can result in major problems. It is generally highly discouraged, unless you know what you are doing or if there is specific instruction to do so.
