Extroot workign, cannot install plugins

[IanBlakeley]

After a couple of tries I have extroot working on a TP-Link TL-WDR3600 v1 with version1.10.0, having had previous space problems with plugins, however, now although it seems I should have plenty of available space

the entire plugin list reports not enough space available

restarted browser as per one suggestion on here. Can I install via CLI?

[oliver]

can you post the output from both 'df -k' and 'mount' (from an SSH session)?

[IanBlakeley]

Sure, here you are

interesting... mine looks slightly different (on a 3600 too)

When you go to the web portal and go to system > plugins does it show the size of the USB drive and the amount free?

I'm not sure how but it looks like something got mounted over the top of your external USB drive

[IanBlakeley]

Picture is in first post just checked, still shows 2.180GB free space on the webguil under system plugins. I've tried rebooting, tried turning off the power and then back on again after a few minutes still the same

[IanBlakeley]

Any idea anyone? Looks like I have more accessible space with extroot off albeit it tiny.

[IanBlakeley]

Finally got to the bottom of this after starting from scratch again. Note still needed 8 attempts at formatting the extroot drive until the router used it. In the end the problem is the symlink pointing at plugin_root is going to the data partition on the card mounted from the tmp folder which never seems to get mounted so does not exist.

Made a directory off the root and changed the symlink

Code: Select all

wxrwxrwx    1 root     root            20 Dec 17 11:19 plugin_root -> /plugin/plugin_root/

Now all seems to be okay, installed the adblock plugin and that's working just need to decide which others I would like

So was it a bug or something else (wrong configuration)?

If it was indeed a bug, would you mind sharing the exact same steps you took to solve it? It might be helpful to others as well (myself included), and probably a definitive fix in the meantime.

I noticed that when running without extroot the USB drive is seen as available. Formatting to get it taken into use as an extroot should leave 75% (assuming) default available as an attached USB drive, I never saw this where I had both.

Digging in via ssh there's a symlink in the root directoy for plugin_root that points to /tmp/usb mount <uuid> (sorry didn;t save the actual). Obviously if the USB is not mounting then the directory doesn't exist and hence there's no space for plugins. I created an directory /plugin/plugin_root and then since you can't edit symlinks I made a symlink in the /tmp directory and then moved it to / overwriting the existing one and effectively moving the location of plugin_root.

I was going to place in the /tmp but of course that gets recreated on a reboot wiping whatever is in there

Code: Select all

root@Gargoyle:/tmp# ln -s /plugin/plugin_root plugin_root

root@Gargoyle:/tmp# mv  plugin_root /plugin_root

So now the / directory is

Thanks for explaining in details. I might give it a try later and see how it goes (never messed with extroot).
