NVRAM

[burrellbloke]

I installed Merlin firmware recently as I wanted to get more out of my router.

I have an ASUS RT-AC3200.

I am now having problems with the NVRAM as it keeps filling up. I have used the command

nvram unset custom_clientlist
nvram commit

To free up some space - but the memory just keeps filling up.

Are there any sensible ways to free up some space on the NVRAM? Can I move any files elsewhere?

Which version of Merlin firmware? Newer builds (380.61?) was to address NVRAM space by using jffs for some data storage. Did you do a factory reset after loading the new firmware and format jffs?

No.

I am new to Merlin firmware. I thought that if I did a factory reset I would lose all of my settings.

I am running 380.61.

Is there anything I can do to make space on the NVRAM without losing my existing settings?

Am I able to edit the NVRAM and delete any particular files?

Hi,

On my AC87U the RAM is stable at: NVRAM Usage 46125 / 65536 bytes - with uptime of several weeks.

What is your usage in bytes?
Did you dump the NVRAM to file and analyze the big entries (beside the custom_clientlist)?
Commands: nvram show > filename.txt and then nano filename.txt

With kind regards
Joe

NVRAM, just like memory, is supposed to be used...

The AC3200 is a little unique because of the 3rd radio. The 3rd radio will take up an additional 9K or so of NVRAM space. Ultimately, you may just have too much configured simultaneously. Every time you enter something thru the gui that sets up something that applies to specific clients it will use up NVRAM....MAC filter, DHCP assignments, port forwards, firewall filters, etc..

Here's a post I made with some suggestions on how to narrow it down......

Thank you to everyone who has replied.

Okay, I had a poke around and the nmp_client_list was the largest file.

I have no experience with these routers, or technical matters like NVRAM. I ran the commands:

nvram unset nap_client_list
nvram commit

I have managed to free up about 5,000 bytes. I have no idea if this is going to result in me bricking the router.

Is there an option in the current Merlin firmware to store items that usually go in NVRAM on to the JFFS partition?

No, this isn't up to the end-user, but to the firmware code to decide where to store data.
