Incorrect data directory for UDM SE in the wiki

rys commented 2 years ago

Package version

1.0.20211208

Firmware version

2.3.15

Device

Unifi Dream Machine (Pro / SE) - UDM

Issue description

In the main wiki page, the installation instructions groups the UDM SE in with the first batch of other devices that have /mnt/data as the main path that you should extract to.

However the UDM SE runs software very similar to the UDR, where /data is the main path you should care about, so it should be considered as similar to the UDR stead of the other UDMs.

Configuration and log output

No response

Hi @rys,

Based on my testing on a friend's UDM SE and feedback from others, I'm pretty sure the UDM SE is using /mnt/data, at least a few months ago when I checked. Just because it uses the same firmware as UDR doesn't necessarily mean it's using the same directory structure for mountpoints...

Can you please show me the output of mount and df -h on your UDM SE so we can confirm?

Regards, Peacey

No problems, I've kept all output just in case there's anything else in there that you might need to see:

Huh, it does seem you are right and it is /data. Well then, I'll change it in the wiki. Thank you for pointing this out. I do wonder if they changed it in a recent firmware, but in any case, it is what it is.

Thanks for bringing this to my attention. I don't have a UDM SE myself so it's good feedback!

Closing this now as it's resolved. Feel free to reopen if you find any other issues. Thanks!
