I am trying to set up a swap partition on my R7800, but it appears the firmware doesn't automatically recognise it and if I use swap-utils in Entware, I get the error 'swapon failed: Function not implemented' when I try and enable the partition.

Any help on this would be amazing as I appear to be running out of memory when trying to use MariaDB.

Thanks

Firmware: DD-WRT v3.0-r49741 std (08/15/22)

I used the Linux Command Line Method in this guide: https://wiki.dd-wrt.com/wiki/index.php/How_to_-_Format_and_Partition_External_Storage_Device

My USB settings look like the below and it seems to work.

[StillBlue]

Very strange. Yes, my USB is partitioned up correctly using Gparted, and the automount does mount the swap partition as Swap, but when I use the command 'free' it shows nothing.

I had no issues with swap partitions on my old WRT54G-TM, but for whatever reason I don't seem to be able to get it to work with my R7800.

[StillBlue]

Oh, is swap disabled in the r7800?

I notice it's commented out.

[dpp3530]

I think you're right. My screenshots before were from a different model. From a similarly configured R7800, I see the same thing you do.

[StillBlue]

Thank you for confirming that.

I may have to build the webserver on an RPi this time then, until perhaps the firmware for the R7800 is fixed.

Thanks for the help.

Should be enabled in the next public release.

https://svn.dd-wrt.com/changeset/49795

[StillBlue]

Excellent, thank you. In that case I will hold on for that.

[kernel-panic69]

Correction: the next next release. I don't know why we're releasing at 49792 when there are later commits that would benefit the community. *sigh*

[StillBlue]

OK, thank you. I will await 49795. I have a few other bits to play with in the meantime anyway.

Thanks again.

I saw this thread and asked BS to enable it if there were no technical reason to prevent it, most especially since it will be nice to find out if wordpress can be installed in the end.

It will likely be a later public build than 49795, anything higher will include it.

You also have the possibility if more space is required to use CIFS automount (Admin tab), for instance if you have a samba server elsewhere on your network and want to use the share directly in DD-WRT for whatever reason like storage.

I also would recommend any swap to be mounted on a fast drive like a SSD, else the swap when used will likely be slow, other sysctl tweaks can also improve this if available on devices. Your favorite search engine is your friend.

[StillBlue]

Thank you.

Yes, it will be interesting to see if WordPress will work or not, I am quietly hopeful.

Looking good.
