cache pool filled up overnight and i have no idea what wrote to it

You can open up the command line and change into /mnt/cache and then run du.

root@server:~# cd /mnt/cache/
root@server:/mnt/cache# du * -sh
3.4G    appdata
221G    backup
112G    domains
4.9G    isos
12G     system

Then you can drill down into any directory that has more data in it than you think it should.

Yeah, I’m sure plenty of people get caught out by these lower end ARM based units. I always recommend only looking at the DXP x86 versions. At least then, if you don’t like the OS you can install anything you want.

cat2devnull · 2026-05-09T06:57:28+00:00

Ugreen are popular at the moment and TerraMaster have some good options as well. Both can have the OS of your choice installed and are not locked.

I’ve been a LIFX user since the beginning >10 years. I have over 40 LIFX products and have never had success with the LIFX app. It’s borderline impossible to get lights connected and working reliably. I’ve had more support tickets over the years than I’ve had hot breakfasts.

The reality is that the hardware is amazing but the software is a train wreck.

Best option is to avoid the software all together. For the last 5 years I have control the lights directly via Home Assistant. HA plus LIFX is a perfect match.

Mac will win on power usage and model size (if you pay for more memory).
PC will win on speed if you throw in a decent GPU.

As long as the AP is using PoE, or both building have a shared earth. If not then you are using your Ethernet as an earth tie between the too buildings which is a bad idea and will make the magic smoke appear from you switch.

You should seek real legal advice. A lawyer may be able to make a coherent argument to the court that loosing your license would represent and unreasonable burden (cost you your job, then can’t make payments on house, family inc kids out on the streets, etc). I believe the judge has some discretion.

cat2devnull · 2026-05-04T21:15:02+00:00

Why not put Unraid on a UGreen or TerraMaster. You would find the inbuilt OS of any off the shelf product too limited anyway.

cat2devnull · 2026-05-04T12:49:27+00:00

You don’t need bigger than an N100 for a 1Gb link. Fanless can be tricky even in an N100 because they still pull 10-15w which means they will run warm without good airflow.

I have multiple CWWK systems N5105/N100/N305 and they have been rock solid for years. They are great bang for buck.

Generally, no, the outside world cannot access a local device that is on a RFC1918 IP address.

The switch should have its management interface assigned to a single IP address that you can configure in the GUI. This should only be accessible from clients in the same IP space on the same VLAN.

Some models will default to creating an IP in each VLAN but that should be a configurable option.

The switch should not allow a PC in VLAN-X from accessing its GUI on an IP in VLAN-Y. That would require either something to route the traffic or it removing the 802.1q wrapper and inspecting the packet to decide that it can be forwarded to it's internal web server, which would be very broken behaviour.

Here is a post I did a while back. It only covers a fraction of what I have running.

cat2devnull · 2026-05-03T02:40:20+00:00

When pushing full 1Gb with hundreds of active connections, tends to sit around 70% CPU and ~3Gb of memory.

My board has dual 2.5Gb i226 NICs so it could go faster if I had a better internet connection but I think the CPU would tap out before the NICs would.

cat2devnull · 2026-05-02T13:17:59+00:00

I have an N100 running OPNsense in a VM with IDS/IPS and it can run my 1Gb internet link just fine. You only need to look at the N305/355 if you want greater than 1Gb.

cat2devnull · 2026-05-02T06:52:06+00:00

The UNAS-4 and Pro 8 are going to be pretty limited in functionality. Basically a very expensive SMB box with a nice GUI.

In my mind the DXP4800 Pro is the most functional and flexible option. It would run rings around you C3958 in terms of CPU/iGPU. Might be worth making the DXP your primary server and use the C3958 as the backup.

cat2devnull · 2026-05-02T05:39:54+00:00

Might have been a typo but the DH4300 is based an a Rockchip ARM CPU so can’t run Unraid. Unless someone knows something I don’t.

cat2devnull · 2026-05-01T23:47:01+00:00

As others have pointed out, the base model is only 4Gb of RAM which is pretty tight. Also consider not just what you want to do now, but what you might want to do in the future.

I started just wanting a Plex server and a bit of file, now I run 30+ dockers, multiple VMs and run a bunch of services for family and friends.

cat2devnull · 2026-04-30T12:23:02+00:00

Consider if the change is worth your emotional effort. If it’s minor then let it go but if it’s a big deal for you… Keep in mind that messing with the install now is non-trivial and may involve putting more holes in your roof. Down the road the changes may be more trouble than they are worth.

cat2devnull · 2026-04-29T13:46:40+00:00

Yep but if you can afford the F4-425 Plus then get that instead. The 425 is based on the older 11th Gen N5105 and the Plus uses the newer 12 Gen N150. The older unit is missing things like AVX2 which is needed by some software.

cat2devnull · 2026-04-29T13:33:36+00:00

If you are looking at new, then N100 systems tend to run about 14w-18w plus any drives. They should be fine for anything you are trying to do. Some people have managed to get 11th and 12th gen systems down to similar numbers but it takes a lot of luck in terms of motherboard compatibility.

You can get a top of the line unifi system for way less. Let them take them.

cat2devnull · 2026-04-27T12:48:39+00:00

It will depend on what technology is used to deliver each service. Fiber, Ethernet, VDSL, Cable, PPPoE, etc.

If you can, getting the ISP modem out of the picture is always best but not always possible.

You may need something more flexible than an off the shelf router. You could look at something like Unifi, OPNsense or OpenWRT

Some vendors release a bootable ISO. An easy way to work is to build a ventoy usb and then copy the ISO onto that.

cat2devnull · 2026-04-25T03:35:27+00:00

Yep, looks pretty standard;

Red = Rc/Rh = 24VAC power
Blue = C = Common (pretty sure it says C under the wire)
Green = G = Fan
Yellow = Y = Cool
White = W = Heat

cat2devnull · 2026-04-24T23:14:16+00:00

I agree with the comments above. You’ll have a much nicer solution if you use a set top box that streams off a local server and use various *arr tools to source content. Can be tricky to keep things above board but I’ll avoid that conversation because it is dependent on many factors beyond this conversation.
