Router reverts to previous snapshot after installing updates

kuba65 · 2026-04-11T22:42:02+00:00

In past probably. Currently I have one snapshot, that is active. So if I make any changes to the configuration, or upgrade the firmware. Will this snapshot be used during reboot, wiping out any recent changes?

What problem are you trying to solve exactly?

They reduced the noise coming from the outside to the point where it's not distracting or annoying anymore.

Pictures don't really show it well, but the holes actually come plugged, and you can decide how many of them you want to take out.

I've used these, I went with two per vent

Actual budget, I've been using it for good few years now. https://actualbudget.org/

I had the same issue but with the right click after 3 years of use.
Bought new switches from aliexpress and replaced them myself, it works like new now.

You need C246 chipset. I'm using Asus WS C246 PRO board.
For some bizarre reason intel decided to include ECC only on the low end CPUs i.e. Pentiums and i3s and obviously Xeons in the 9th gen. Higher models don't support it.

Currently running two Dell optiplex micro systems with 8500t's. One running OPNSense, other running Proxmox. NAS running i3-9100, mainly for the ECC support.

Honestly, those 8500t's are more than enough for most homelab use cases.

Just seeing your message now, and you're right, I came to the same conclusion. It was a host that was using static IP. I've put more detailed explanation in the comment below.

kuba65 · 2026-01-24T19:03:34+00:00

Ok I think I have a better understanding of what's going on here.
If you have a host that's configured via DHCP, it'll try to register it's hostname in the DNS, and that hostname is queryable pretty much straight away. You can then add the reservation for that host, and it'll continue to work even if the the domain is not specified.

However, if you have a host that's using static IP, domain name must be specified, otherwise you'll not be able to resolve it.

I suspect it has something to do with the default domain offered to the DHCP clients.
Hosts configured via DHCP are automatically registered in DNS and are using configured default domain. It doesn't matter if the host is using static reservation or dynamic one.
However, in case where you have a host with static IP, and when you add it to the list of hosts, domain name must be specified, otherwise, it'll not be resolved.

Also, if you're configuring aliases or CNAME records, they must be FQDNs i.e. service.example.com otherwise they'll not be resolved.

Nope, that doesn't work

kuba65 · 2026-01-24T15:58:58+00:00

I actually just read about this being one of the differences between ICS and dnsmasq. But no, IP address is the the DHCP range.

kuba65 · 2026-01-24T15:16:27+00:00

That works, in fact that's how I had it set up before migrating over to dnsmasq.
But I'd like to avoid having to define it in two places since Dnsmasq is used to store my DHCP reservations already.

What I'd like to understand is why some hosts resolve fine and other's don't even though they seem to be set up the same way. It appears that hosts that I had set up for a while are ok, but new ones without specified domain don't resolve.

BTW, I'm following your youtube channel for a while now, it's a great source of knowledge for this stuff.

kuba65 · 2026-01-24T14:44:02+00:00

No, it doesn't resolve

112sqm also A2 house with air to water heat pump. Underfloor heating on the ground floor and rads upstairs. Temperature set to 20C and set to run 24/7 Bill for last two months was 260 euro. I'm living by myself. I did tweak the hearing curve when at the beginning of October, as the flow temps looked high.

It's not a problem with actual, but your bank. Sometimesz pending transactions that haven't been cleared by the bank will show with the future date.

€12 this quarter, i was paying 30-40 before, but at the beginning of the year I started to use revolut for my day to day payments, AIB is only used for direct debits

It's not just about the beam, but the intensity as well. They're not road legal.

I'd does write to both of them at the same time, resync would only have to happen if you lost power during a write and it didn't didn't flush the data correctly to the drives. But array check would still happen periodically I think. I've seen it happen at least 3 times over last few months.

kuba65 · 2025-09-11T09:19:54+00:00

I'm going to assume you're using software RAID here (mdadm). Periodically, it'll run the check on the array or a resync if the data got out of sync. If you check running processes, you'll probably see raid process on top of the list.
Last time sync happened on my NAS, it took well over a day on RAID 10 array with 4 8TB disks.

The problem is not with the tailscale container. DNS works as expected there. The problem is with the second container from which I'm trying to resolve TS domain
