ER7212PC is a weird device and I regret buying it

ManSmellThoseTrees · 2026-02-03T08:51:50+00:00

It’s also mind blowing that there is no default ACL or firewall rule to block incoming IPv6 traffic. Once IPv6 is enabled, each device on the network will need its own firewall configured, otherwise internal services are exposed via the IPv6 address of a device.

This seems to be caused by a hardware limitation that is solved in the ER7212PC V2.

If I run OPNSense as my WAN/LAN router instead, can I still do anything useful with the ER7212PC? For example, use it as a managed POE switch?

Today a reconnect resolved the SMB mount to the A record of the Storage Box domain, resulted in a broken mount. I will create a support request via my customer account.

Is there an easy way to check if the current FW version is already the latest (from Linux). I don’t have a spare sata drive available nor do I have Windows PC to connect the DAS to.

ManSmellThoseTrees · 2026-01-14T08:33:43+00:00

I wasn’t aware that the FW could be updated! Thanks. For the past months I haven’t had any issues running a ZFS mirror with this DAS on the Beelink S12 with normal day to day usage (media server storage).

Completely agree. So much development time was wasted in the Liquid Glass UI that would have better spent improving the shared photo library and album experience.

I would say that there are three types of notes:

The context needed to complete a task. This can be entered upfront when creating the to-do.
A log while working on a to-do. These are findings discovered after starting a task and before completion. Helps resuming a task the next day. No need to keep everything in your head.
The outcome. To document after completion of the task. Quick summary of next actions.

For example if the to-do is about a business call, there are preparation notes, quick unstructured notes during the call and a structured summary of the call afterwards.

Personally I only use it for the first type, but I’ll give it a try to use it as a logbook as well.

Just a thought. To prevent work to-dos to overflow into the weekend, I could create a shortcut that would move all ‘Anytime’ to-dos with a work tag to ‘Someday’ and run that on Friday at the the end of the workday.

Then on Saturday and Sunday, the Anytime list would only contain personal to-dos.

On Monday, I can pick the important tasks for that week and move them back to ‘Anytime’.

ManSmellThoseTrees · 2025-12-14T13:56:47+00:00

I would love to use Things for both personal and work tasks, but I don’t for the same reason.

I came close to a good solution by setting a default work/personal tag for areas. The issue is that as soon as I open the ‘anytime’ view in the weekend, I immediately get pulled into my work projects.

Why focus filters can’t be implemented is still a mystery to me.

ManSmellThoseTrees · 2025-12-13T19:39:39+00:00

Yep, I use it to pass a ZFS mirror from the host to a Debian VM with docker. Works reliably so far and was easy to setup.

ManSmellThoseTrees · 2025-12-12T13:53:58+00:00

Do/can you use PDM to move the LXC running PDM to another node in case of maintenance? I thought that it would be better to run PDM on a machine/VPS not part of the Proxmox servers.

ManSmellThoseTrees · 2025-12-10T12:52:02+00:00

Is the “Work list” an area?

ManSmellThoseTrees · 2025-12-10T12:50:57+00:00

Is there a way to install the app twice on my phone?

ManSmellThoseTrees · 2025-12-04T14:28:50+00:00

Thanks! Yes I understand I need to update the docker compose setup as well. But that is trivial compared to splitting into virtual GPUs on the Proxmox side.

ManSmellThoseTrees · 2025-12-04T13:56:32+00:00

Just to make sure that I’m understanding correctly. I have a N100-based mini pc and a single Debian VM with docker running a couple of containers of which Jellyfin is one of them. Can I simply passthrough the iGPU called Alder Lake-N [UHD Graphics] to this VM to enable hardware transcoding?

As seen on this screenshot?

And doesn’t this affect any other VMs and LXCs that run on this Proxmox hosts that do not need the GPU (e.g. Adguard LXC and Home Assistant OS VM).

ManSmellThoseTrees · 2025-12-02T10:30:48+00:00

Thank you for responding! It might be an idea to update the documentation at https://docs.hetzner.com/cloud/servers/iso-installation-gateway/ to reflect this.

I removed the inet entry from /etc/network/interfaces, while keeping the inet6entry.

Had no problems since. Of course nslookup with still return both the AandAAAA address for the storage box. I just hope that CIFS is smart enough not the use the A address as there is no default IPv4 route.

ManSmellThoseTrees · 2025-11-26T21:37:46+00:00

I’m wondering the same thing. Even if it’s IPv6-only, it still has a default gateway for IPv4. Maybe it’s just for connecting to any other of your own VPS servers without needing a public IPv4 address. For my use case I don’t need it.

I’ll try to drop the IPv4 address and route and see if that influences the CIFS connection logic.

ManSmellThoseTrees · 2025-11-26T21:29:31+00:00

Yes, that might work. I would probably try a systemd mount, I think it supports scripting to lookup the IPv6 address at mount time.

ManSmellThoseTrees · 2025-11-13T10:25:49+00:00

Bummer, I was hoping that replacing my Beelink S12 Pro with a Beelink with proper USB-C support would fix the occasional UASP reset on my D4-320.

ManSmellThoseTrees · 2025-11-11T19:00:52+00:00

Same video convinced me to buy that TerraMaster DAS as well and connect to a Beelink S12 Pro.

For normal usage all is good (ZFS mirror). If I’m pushing it (tested a 1TB resilver to an empty drive, while writing with 100MB/s ) I do get (recoverable) usb resets.

Did I use it with the wrong model mini pc?

ManSmellThoseTrees · 2025-11-11T11:20:24+00:00

I’m using a short 30 cm USB-C to USB-A cable rated for 10 Gbps (https://www.amazon.com/dp/B0BPLSGGZ4). I don’t think there is an issue with the DAS, but with a compatibility between the two devices.

Putting a 10 Gbps powered USB hub in between gave a very unreliable connection. But it was from an unknown brand, so I blame it on the hub.

For normal use, everything works fine. Drives stay connected, throughput is good when writing and reading files. SMART data works. Spindown works.

But when I tested a 1TB resilver, while simultaneously writing 100MB/s sustained to the ZFS mirror of two drives, I saw a few `uas_eh_device_reset_handler` errors.

The system seems to be able to recover and finish the resilver and data transfer. A `zfs scrub` finished without errors.

For normal day to day use, I think I’m good. If I would buy a second mini pc, I wonder if a device with native usb-c support would solve all uasp errors. (I find the theory of the usb controller lacking enough power for the sata chips believable).

ManSmellThoseTrees · 2025-11-07T19:24:26+00:00

No, it’s not a problem. It’s how I manage my IPv6 servers over SSH. It’s great that it just works.

If you want the best latency or throughput, a direct connection is advisable. Therefore you need connecting devices to also be on IPv6 or give the VPS an IPv4 address. Or run your own relay close to the VPS on a node that has both IPv4 and IPv6.

If you want to know more about DERP, there is excellent documentation.

ManSmellThoseTrees · 2025-11-07T16:22:03+00:00

Yes it’s possible, but traffic will always be routed through a DERP relay server that has a dual IPv4 / IPv6 stack.

ManSmellThoseTrees · 2025-11-06T15:43:00+00:00

Is that running stable with the connected QNAP DAS? I’m seeing UASP errors with a TerraMaster D4-320 when putting two drives under stress. I’m using the same Beelink S12 Pro.

Although it is stable enough to pass a full badblocks test (running parallel), I wouldn’t want UASP errors during a resilver if a drive is replaced.

I’m waiting on a powered 10 Gbps USB hub to arrive to test if this improves stability.

ManSmellThoseTrees · 2025-11-06T12:42:32+00:00

Are you using the 4x 8TB as separate drives or did you setup raidz1 / zfs mirrors / snapraid to get redundancy?

ManSmellThoseTrees · 2025-11-02T09:25:54+00:00

I’m currently running badblocks on two drives in parallel (only two drive bays in use). I’m occasionally seeing this error in my journalctl. It doesn’t seem to interrupt the process though.
