HD space questions

Hi,

I’m looking at hd space:

and am wondering if a usb key would increase the total as HD space, or if it would be counted as different space.
I’m worried if it needs to be manually cleared of cruft, like old logs, tmp files, stuff like that.

I know there’s a thing called “the dude” that requires a usb key, and have read elsewhere that logs can be made to
write to the key. I’ve yet to read about automatic log trimming though, am worried log files might fill up the “HD” with the size it is.

Added USB key counts as separate HD space. It can be used for everything that allows to set files location explicitly (the dude, containers, rose storage, logging to disk, …), but not base ROS installation or location for upgrade packages (to upgrade router itself).

OK, thank you. Do you think 32GB is a reasonable size for any future additions? There’s a tiny USB3 stick I can use.
Also, is the HD space (as shown in the graphic) considered “low” - I mean do I need to do some tidying up (manually)?
The routerOS recently went from version6 to version7.

Having 4MB free out of 16MB of storage is decent. And will probably suffice for v7 as well.

Whether 32GB is enough for your future endavours or not is entirely up to you. My MT devices run with zero added storage just fine, but my (home made) multipurpose networked device is tight at 8TB. So YMMV.
Beware that many USB3 devices interfere with 2.4GHz WiFi, specially so if device itself uses WiFi.
