GL-MT300N-V2 - GL.iNet after upgrade to 3.201 Free space: 6% (0 MB)

I wish there was a sample for anyone who wants to start learning about their own init scripts.
It doesn’t have to run successfully. Rather, It’s best to nothing is done as it is, and it should only work by removing the failsafe.

It is important that it is not a “patch” that an inexperienced user just copies, but a “template” for beginners to start learning.
It needs to be clarified, because it is impossible to write a script that just write once and it run anywhere

You can’t compare embedded linux to something like Ubuntu. OpenWRT has it’s own config files. It is also OpenWRT that directly recommends not to keep configs going from major versions.

@GL-FUN @makino16

Automatic Configuration Script Technical Support for Routers

I use the script bellow to configure my routers every time I do an upgrade of the firmware. I don’t like having a lot of residual files taking up space, and when going from one version to another it is not recommended to save settings when doing an upgrade. The script is for the S1300, and you will need to read it and go through changing some of the values for your router, but its a good starting point. You can copy individual lines of the script and run them to see what is going on and you can…

@Johnex this gadget might be in hands of those, who may not know how to do it. your advice is not very useful for those, sorry.

alzhao:

I tried upgrade from 3.105 to 3.201 and the available storage is normal.

can you tell me, what is normal, and how I can check that that on my side, please?

Johnex · 2021-04-19T09:39:22.425Z

@GL-FUN You are welcome . I’m sure it will be useful for a lot of people including @makino16

GL-FUN · 2021-04-19T09:43:32.780Z

Johnex:

I’m sure it will be useful for a lot of people

i am sure! it is useful for me too, but not all users even understand what you are talking about. and, therefore, for those, it is not good to progress solving their problems…

Go to applications → plugins and you will be shown how much space left for you.

After install 3.201, you should have around 2MByte

applications → plugins: Free space: 3% (0 MB)
i had to uninstall nano (the one i installed previously), sms, smtp, and ppp packages to install luci.
the space now is with luci installed

However,

I didn’t do a detailed comparison, but many of my files have different sizes. Some more, some less. I have some you don’t. I would be bothered by the different sizes.

It might be nice to get rid of some of these packages, or have them installed if needed. I don’t need a captive portal, for example,so dumping nodogsplash would save a little bit. I wonder if we could dispense with the MAC database, too.

i wonder if that is safe to remove, too, please?

eric · 2021-04-21T12:09:07.533Z

I totally agree with making the MAC database optional. It is taking up almost a megabyte which if it was an option, would give us almost 50% more free space, going from 2MB available to about 3MB.

GL-FUN · 2021-04-25T15:56:13.282Z

All right, can we say with authority the MAC database can be removed?

elorimer · 2021-04-25T19:00:08.231Z

I think the mac database is used for exactly what you expect, attaching a vendor name to a mac. The tertf directory I think is used by gl-tertf for monitoring client traffic; gl-tertf is started in etc/init.d.

I reset the Mango to factory defaults, set up its wifi, then connected to the local wifi. Applications|Plugins reported 19%/2MB free space.
I installed LUcI; now 14%/2MB free.
I opened luci|System|Software, which reported 59%/2.4MB free.
using ssh, I removed /etc/tertf/mac_vendor.db, and then /etc/init.d/gl-tertf and rebooted.
Back In luci|System|software i now had 73%/2.9MB free. I uninstalled gl-tertf, which left me with 72%/2.9MB free (?). It looks like this tried to uninstall /etc/init.d/gl-tertf, so I didn’t need to have done that. It also looks like it uninstalled the sqlite library.
I installed adblock, sqm, nano, htop. This brought me to 57%/2.3MB free
I installed sqlite, which brought me to 40%/1.6MB free.
Rebooted. We’ll see now.

GL-FUN · 2021-04-26T08:46:38.098Z

can we compare, please?

and what size exactly is being reported by those %%?

The Luci percentages all compute out to a percentage of 4MB, which would be around the 3.6M mounted as /overlay, left over from from the 16M flash memory not used by the firmware. I think the GL GUI might be reporting it as a percent of the entire flash memory.

If I do df -h, I have 10.5M used and 0 available in /dev/root, mounted as /rom, and 1.5M available of 3.8M in /dev/mtdblock6, mounted as /overlay.

Not sure how you have 6.3M in overlay, which implies more than 16M flash.

OK, i figured - bind utility took the extra space. would be still great if the frm upgrade would check the space and advise.

I realize this is an old thread, but I’m having a similar problem.
Brand new X750V2 w/ 16Mb of flash memory.
Came with 3.201 installed.
I haven’t done an upgrade or added anything.
When I attempt to install Luci, a get the “Not Enough Flash Space” message.
