Yep, I understand that. I didn’t know if RAID 6, having parity bits, would be able to repair a file from that data. I figured being RAID would protect it from corruption but apparently not. I didn’t overwrite the file with a bad one, it just stopped working.

 

I have a RAID 6 volume with data protection on my DS1621+. A video file seems to have become corrupt - it worked in Plex a few months ago but now it won’t play at all. I’ve tried in VLC, the built-in DSM video player - nothing seems to work. No other files appear to be corrupt, all drives show as Healthy.

Is it possible to repair the file, and if so how would I do that? My research seems to only find results where an entire volume is corrupt. In this case I’d like to just recover a single file.

 

Apologies if this is a common question - Lemmy search leaves a little to be desired still.

How exactly does a Thread border router talk to edge devices? Do they talk directly, device-to-device or will a border router utilize the 2.4GHz radios in my APs to extend its range?

What are your thoughts on TrueNAS Core or Unraid instead of Synology? I could still run Plex on the same hardware that handles the storage while maintaining the freedom and flexibility that my current home lab server provides. There appears to be plenty of decommissioned enterprise-grade hardware being sold on FB all the time.

Again, pardon my ignorance when it comes to Kubernetes. Why would I use something like k0s instead of just regular old Docker? I suspect PCIe passthrough will have similar challenges on both k0s and Docker, whereas on Proxmox it's been relatively painless.

This might be better suited for a different community, in which case I'll make a post where appropriate. I'm not familiar with some of the Kubernetes terminology - batteries, pod/manifest (is this similar to stacks/docker compose?), NodePort?

I apologize for my ignorance when it comes to Kubernetes - I sort of wrote it off as complete overkill for a home lab when my very basic understanding was that it was essentially a load balancer. After some light research, I'm beginning to understand that it could be a better solution than a full-blown hypervisor.

If I understand your comment correctly, you're suggesting to simply run a lightweight distro and install k0s or k3s to run containers? What would be an ideal bare metal OS for this? What would be pros/cons to k0s vs k3s in a home lab environment, or is that simply a matter of personal preference? What would be the best way to connect to my media - SMB, NFS, something else? Or are the differences here irrelevant? Any concerns (permissions, IO latency) when passing an NFS mount from host into a container, or is there an even better way to do something like that entirely within the container?

 

I’m looking for some feedback on my Plex system architecture.

All my media is stored on a Synology DS 1621+, six 4 TB drives in RAID 6 with one acting as a hot spare. All four network ports are bonded into a 4G link to an Ubiquiti USW-48-POE.

Previously, I ran Plex in a Docker container on the NAS. This setup was stable; however, the NAS only has 4 GB of memory shared between Plex, several other Docker services, and regular DSM overhead. Plus, the processor is not very powerful (AMD Ryzen V1500B, ~5400 PassMark).

A few months ago I repurposed some old desktop PC parts to build a home lab Proxmox server (Core i7-6700K [~8900 PassMark], 32 GB memory, GTX 970, an old 2.5” SATA SSD for guest OS disks, 1G networking on the motherboard). I’m running Plex on an Ubuntu VM, with the GPU passed through directly to the guest OS. Plex is not containerized in Ubuntu. The VM has 8 CPU cores and 8 GiB memory (different units in Proxmox). My Plex media is accessed via a persistent NFS mount in Ubuntu (had been SMB before a DSM update broke something and the VM could no longer read the directory contents.)

The main purpose of the change from NAS to VM was to utilize the increased CPU/GPU horsepower and memory that I had lying around, but I worry that the added layers of complexity (hypervisor/VM, PCIe pass through, NFS mounts) will introduce more opportunities for performance issues. I have noticed more frequent hiccups/buffering/transcoding since the change but I’m not sure if it’s related to my setup or if those issues lie with client devices and/or the files themselves (e.g. weird file container type that the client can’t play natively).

Any critique or recommendations on system architecture? Should I get a dedicated NIC to pass through to my VM? Dedicated NVMe drive passed through as a guest OS disk? Ditch Proxmox altogether and go back to Synology Docker container?

First you have to convince him that the earth is more than 8000 years old.

The Fn and Carl keys can be switched in software. I have a work-issued Lenovo with a similar layout. They can be soft-swapped in the BIOS. There’s also a desktop utility to do the same but I don’t know if they have a Linux version of it. I totally agree, the physical layout is annoying but it has a simple fix.

Then this is false advertising and a class-action lawsuit that should have already happened.

This Arstechnica article seems to confirm that they can't decrypt without user intervention and that they have only ever supplied metadata to law enforcement. I'm no fan of Meta but do you have sources that they have in fact decrypted actual message content at the request of law enforcement?

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

No disagreement there. I could have clarified, my comment was in regard to message content only. I didn't realize that about metadata and certainly am not defending Meta. I'd prefer Signal over anything else but as others have mentioned, getting friends and family to adopt is painful.

It’s still E2EE, as far as I know. Meta could always remove that feature but until they do, I’d consider it a safe and private messaging platform.

Update on my SN30 Pro - I haven't noticed any Bluetooth input lag whatsoever. I'm using an RPi 3B (not 3B+). I read on the RetroPie forums that any input lag over BT can be mitigated by overclocking and also that it's less of an issue on the newer models, so if you're using a RPi 4 you will probably be fine with BT.

Agreed. I don't think there is a gamer on the planet who would balk at any extra cost to have hall effect sticks in every single controller. Can't imagine it adds more than a few dollars.

3rd party, 8BitDo seems to be the best/only option. They have both Bluetooth and 2.4GHz options. I have some concerns with Bluetooth input lag but I am expecting a Bluetooth SNES gamepad to arrive today so I can update with my experience later this evening.

2.4GHz

They have some other controller options as well, but make sure you get one with enough buttons. Their 2.4GHz SNES controller only has the standard SNES buttons so you'd either have to sacrifice one button to use as Hotkey (typically Select) in which case you can't use that button in-game, OR you just won't have a Hotkey in which case you need a keyboard to exit emulation.

Then there's always standard Xbox and Playstation (and probably Switch Pro) controllers. 8BitDo sells a 2.4GHz adapter that is supposed to work with those first-party controllers, or if you have a newer Xbox controller it will have Bluetooth built-in.

 

Wondering how people set up hotkeys for simple controllers like an SNES-style controller? Pretty much all guides say to use Select, but some games require the use of Select (e.g. Donkey Kong Country for switching characters, Super Mario World for exiting a level). Is there a way to use a combination of buttons as a hotkey? Or a secondary controller/keyboard for accessing the RetroArch menu from within an emulator?

 

This morning I updated my DS1621+ from DSM 7.1.1-42962 U6 to DSM 7.2-64570 U1. After the update I am no longer able to access shared folders from my Ubuntu machine. All errors in terminal and Portainer indicate "access denied", though no passwords have changed, and I am still able to access the shared folders from Windows. I am mounting shared folders with SMB but also tried NFS when SMB stopped working, as that appears to potentially be easier to manage (no usernames/passwords?).

Any help or direction to a fix is greatly appreciated.

EDIT: Realized I had a typo in my mount command for mounting an NFS share - I was using ip.address:/shared_folder instead of ip.addres:/volume_name/shared_folder. Fixed that and now have no problems using NFS to mount the shared folders to the same mount point as before, so for me that's a suitable workaround and presumably a better solution than SMB anyway, since both client and server are Linux OSes anyway.
