Space ran out on Hap ac2 - is it safe to run it like that long term?

Not looking to upgrade the fw (it's a remote router from where I am), but wondered if it's safe to run it as is with 0 space available? Or will it eventually 'brick' itself (the way e.g. linux machines do if they run out of space)

Also, with an uptime of c.4 months, I wanted to restart it now as wg s2s started glitching out of nowhere (space related perhaps?) and bit worried it may get stuck at boot if the drive is completely full?

FWIW, is there a way to free up more space (not sure if I can delete these files/folders safely?)?.

No, it's not safe, so you should act on it as soon as possible.

Very likely it won't just crash (but it might), however it is very likely that it'll experience some problems if it happens to reboot for some reason (e.g. power outage or some such). And problems can range from (relatively benign) applying configuration which doesn't include most recent changes and to entering a boot loop (which can be only broken by netinstalling device).

It is very linkely that you'll have to reset config to factory defaults (the milder variation) or netinstall device (the more brutal variation) to reclaim used space. After that you will want to check configuration and possibly remove some of it. E.g. using large address lists (with non-dynamic entries) can use up considerable amount of flash space.

Export config to terminal and copy config to notepad and save as rsc file.
Then netinstall to latest v7.15rc and install the acwave2 package. You will have enough free space afterwards. Restore your config you exported

Then make sure to:
1. Lower your DNS cache size
2. Disable graphing saving to disk
3. Disable DHCP leases storing to disk
4. Delete unnecessary files like skins, hotspot files and autosupout.rif
5. Create a small ram disk where you can temporarily save backups etc from now on

Just discovered by accident that it's now possible to run zerotier again on the Hap ac2 using 7.15rc1 (testing) !!

MTIK managed to optimize the base package + wifi + extras so that it'll fit into the sparse flash space. Congrats !

Ok, there is not a lot of space left.
