Anonymously report them. Don’t call police they will come and take the server

You could scp them from server out, you can setup simple http and grab via web, you can use a phone and take a picture, you can read them on the server and type them here. Lots of ways besides ssh into the machine from a client

People are replying like they are because you have asked for help but aren’t able to provide details on the steps, the yml files, or other commands you executed. Essential it is like when my wife calls me on my phone and says “I’m lost, where am I?” And I have no clue where she is because she can’t provide me street names or what direction she is travelling. Basically nobody here knows where you are.

It has been working well for us, we have a central work server and most use WebGUU, but some of us have the Sync or Drive Client and Phone Apps. I only had to pause sync and restart for a file that wasn’t syncing once in about 9 years

Have you tried Seafile. https://www.seafile.com/en/home/

It has server and client. And you can choose what to sync, so you don’t have to pull down entire folders.
Also has a webgui. Client side has Sync client or Drive client for Windows/Linux/Mac.

Drive client works more like a network drive so you don’t need to sync the files.

Also has Android/ IOS app

I personally believe you are overbuilding. For example my OpenMediaVault Samba Server and DLNA server runs on a SingleBoard that has 256 megabytes of RAM. Yes MB. And it still has RAM free without swap. And I should alter my clock.

You can have more than one drive on a pi, either USB, or they sell sata boards

Not sure on MergerFS…I haven’t gotten deep into ZFS pools.

What ZFS are you using?

“As of November 2023, this feature was merged in main and is scheduled for release in OpenZFS 2.3:”

'The OpenZFS project (ZFS on Linux, ZFS on FreeBSD) is working on a feature to allow the addition of new physical devices to existing RAID-Z vdevs. This will allow, for instance, the expansion of a 6-drive RAID-Z2 vdev into a 7-drive RAID-Z2 vdev. This will happen while the filesystem is online, and will be repeatable once the expansion is complete (e.g., 7-drive vdev → 8-drive vdev)."

Awesome! Interesting with MTU. This was a first hit google search, seems MTU in wireguard setup plays a role also. https://gist.github.com/nitred/f16850ca48c48c79bf422e90ee5b9d95

It may not even be the issue, I’m just spitballing, and it maybe DNS issues like others mentioned or cell provider blocking some aspect. As you probably know Wireguard can be set for all traffic to route through the tunnel, or some outside of it. Maybe cell network is not routing DNS through the tunnel, but using its own, or maybe they used a cached Domain name lookup that doesn’t have your domain IP. Again, networking/DNS etc is my blind spot. I.e. I have setup openmedia vault on a 256MB RAM arm board to serve my music and SMB shares, but I don’t understand reverse proxy LOL.

I don’t have a lot of networking skill here, but could it be your WiFi connections (anywhere) are IPv4 and on mobile it forces IPv6, thus why you can connect via IP:port? Typically your wireguard host machine has IP forwarding/masquarading setup so you can reach your home LAN. Could this be an issue through the router / proxy?

Yes, but No, but. It’s like an always on self discovering VPN. No need to connect and login if you lose connection or change from WiFi to cell to Ethernet, it just figures it out. And as other commentor said it is wireguard. So you can set it up yourself without a 3rd party, just takes a little bit of tech savvy skill and trasfering some public keys between each set of connections. Tailscale just makes it effortless.

If it is a one time transfer, plug them both into a PC ,set USB as file transfer then copy the folders over

Does this count ARMv6 256MB RAM running OpenMediaVault…hmm I have to fix my clock. LOL

Something like fslint might be what you want. Scan folders, lists duplicates, you set how you want to deal with them. Its more manual, but I think it is what you are actually trying to achieve.

Thanks, that’s a great write up

I guess in my case the batteries may have had enough to signal they were functional, but they were effectively dead and had no UPS backup sustaining power. One battery had started to buldge its container. I can see it as being an as designed feature, that way they never let you down in a powerfailure event, as you get advanced notice that the battery is no longer working LOL. Had a corporation go down a few years ago, they had not replaced UPS batteries, when power wentout all UPS batteries were dead and couldn’t sustain the servers until backup generator came online.

My CyberPower is 14 years old now still working fine, just needed battery swap at 10 year mark.

Haven’t had this happen. Battery pack failed after 10 years. Unit still provided mains AC through battery backup plugs. There is a switcher inside to flip between mains and battery…maybe that was going bad in what you describe.
