I'm running Jellyfin in Docker in my home server for movies and shows. I recently added a music directory and apparently after that I'm getting almost hourly notifications from my Uptime-Kuma instance connected to Gotify that Jellyfin is down with status code 502. It's quickly up again, but I'm wondering what's causing this.
I have Nginx Proxy Manager configured for a local and a public domain pointing to my Jellyfin instance.
Any idea what could be causing this?

I just discovered the Sota Remix of Bring Me The Horizon's "Can You Feel My Heart" and feel like I've heard it in someone's set, but I don't know who's. I listened to a lot of Nitepunk, Imanu, Buunshin, DJ Ride, Gladde Paaling and Luude lately. Maybe someone recognizes it.
Here's the track: https://www.youtube.com/watch?v=6SRzEgCY0Xs

I have an Intel Core i5-7600K and just passed through my Intel HD 630 iGPU from my Proxmox host to a virtual machine running Debian to be able to use it in a Jellyfin Docker container. Everything worked fine, but I used only the basic configuration that I found which I don't really get. Can someone explain to me whether I'm missing something?

First I followed this tutorial: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/
But I only added intel_iommu=on iommu=pt to my boot parameters and vfio, vfio_iommu_type1, vfio_pci, vfio_virqfd to /etc/modules.

But what are all the other parameters good for?
pcie_acs_override=downstream,multifunction initcall_blacklist=sysfb_init video=simplefb:off video=vesafb:off video=efifb:off video=vesa:off disable_vga=1 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 modprobe.blacklist=radeon,nouveau,nvidia,nvidiafb,nvidia-gpu,snd_hda_intel,snd_hda_codec_hdmi,i915"

Then I added the iGPU as a PCIe device to my VM using the Proxmox webUI and added the render device /dev/dri/renderD128 to the Jellyfin Docker container.
I followed the official instructions from Jellyfin: https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/#configure-with-linux-virtualization

But I haven't added the host group ID, what is that good for?
And I also installed the intel-media-va-driver, i965-va-driver and firmware-linux-nonfree as well as firmware-misc-nonfree. Are all of those necessary?
And then I had to add options i915 enable_guc=2 to /etc/modprobe.d/i915.conf to get it to work. This is supposedly only necessary for Low-Power Encoding, but it was necessary to get hardware transcoding to work at all?

I'm happy that it is working now, but I don't really feel like I fully understood what I did. Were some steps unnecessary or did I miss anything?

I followed this guide: https://notthebe.ee/blog/easy-ssl-in-homelab-dns01/

But my Nginx Proxy Manager is running on a VPS that is connected to my local network through a WireGuard tunnel. Could that be an issue? I don't know why it's not working?

My NPM is also accessible to the local IP of my homeserver on which WireGuard is running.

I want to start Konsole in Split View which is possible using the --layout command but then also run a command like htop in one of the sessions. How do I do that?

I'm currently using BackInTime and TimeShift to create local backups of my system and personal data. I configured both to keep 7 daily, 4 weekly and 6 monthly backups. I use this setup on my Desktop-PC as well as on my laptop.
Now I also use BorgBackup to create an additional backup of my local backups and right now use the same retention policy, so keeping 7 daily, 4 weekly, 6 monthly and 1 yearly backup.
This turned out to be a lot of data and my 1 TB off-site storage solution is currently using 953 GB of storage.
Now I was wondering if my double retention policy is even making sense and what others are using. So how long do you usually keep backups? How many backups do you keep and what would you suggest for my setup?

Solved, see below.

I recently reinstalled my home server and was unable to open my LUKS-encrypted hard drive. Neither my usual passphrase nor a newly created keyfile were working. I tested on different distros, initially on my new Proxmox installation, later on a the Arch ISO. I eventually tried the disk on my main system, on which it used to be and I still had an old keyfile on - et voilá. So I created keyfiles as suggested in the wiki and occasionally md5sum returned a different hash for the keyfile! Why is this happening? I find' this extremely concerning because this could potentially result in massive data loss due to a keyfile apparently randomly not working as I was experiencing it. What am I missing?

For reference because I don't know how to share what I exactly did.

Scenario #1:
A directory on a mounted hard drive on my desktop.

$ echo -n '$mypassphrase' > ./dir/keyfile
$ md5sum ./dir/keyfile
 c6dd9329dbe030127ce5e19d85de4df9 ./dir/keyfile
# chown root:root ./dir/keyfile; chmod 400 ./dir/keyfile
# md5sum ./dir/keyfile
c6dd9329dbe030127ce5e19d85de4df9 ./dir/keyfile

Scenario #2:
My old keyfile in /etc on my desktop containing $mypassphrase.

# md5sum /etc/keyfile
a1c10c2d023c982259f6c945ebee664e /etc/keyfile

Scenario #3:
Booted from the Arch ISO on my server.

# echo -n '$mypassphrase' > keyfile
# chown root:root keyfile; chmod 400 keyfile
# md5sum keyfile
c6dd9329dbe030127ce5e19d85de4df9 keyfile

Scenario #4:
A directory in /home on my desktop.

$ echo -n '$mypassphrase' > ./keyfile
$ md5sum keyfile
a1c10c2d023c982259f6c945ebee664e keyfile

EDIT: I just moved the disk back into my server and tried echo'ing my passphrase into a keyfile which returned the hash starting with c6, whereas opening a file using nano and pasting the passphrase into the file returned the hash starting with a1.

EDIT: I moved the disk back into my server, reinstalled Proxmox and tried again. I was able to unlock the disk after I pasted the passphrase into a file and deleted all trailing spaces/newline. I also tried echo'ing the passphrase into a keyfile and that also did not work, no clue why but it seems to work on some systems on not on others.

I currently have a server running Arch Linux and Jellyfin, one Raspberry Pi 4 running NextCloudPi and one Raspi running Pi-hole. Eventually I want to host all and more services on one maschine.
I thought about using Proxmox and Docker, but I'm not sure what the ideal setup would look like. For now I thought I use Proxmox and a simple Debian VM which I run Docker on and running Portainer, Pi-hole, Nextcloud, a reverse proxy and Jellyfin as Docker containers?
Is that a smart setup? It gives me the ease of using Docker and a easy way of creating backups of single applications or the whole VM, leaving me with the possibility to add container or VMs for various other services, for testing etc. Or should I just use LXC for said applications?
Any guidance would be appreciated!

EDIT: In case my comment was overlooked. Thanks for all your comments, I'll see how I implement things when I get the time to reinstall my server.

I just bought and set up a Shelly Plug S. It's advertised that the LED is changing color according to the power consumption relative to the max power limit. But I can't find an option to set the max power limit in the WebGUI. How do I set this?

As you might now, the mod team of r/LinuxCrackSupport abandoned the subreddit due to the recent API changes.
