tldr: I’m going to set up raid z2 with 4x8TB hard drives. I’ll have photos, documents (text, pdf, etc.), movies/tv shows, and music on the pool. Are the below commands good enough? Anything extra you think I should add?

sudo zpool create mypool raidz2 -o ashift=12 /dev/disk/by-id/12345 ...

zfs set compression=lz4 mypool #maybe zstd?
zpool set autoexpand=on mypool
zpool set autoreplace=on mypool
zpool set listsnapshots=on mypool

With ai raising hard drive prices, I over spent on 3x10TB drives in order to reorganize my current pool and have 3 hard drives sitting on a shelf in the event of a failure. My current pool was built over time but it currently consists of 4x8TB drives. They are a mirrored stripe so a usable 16TB. If I understand it correctly, I can lose 1 drive for sure without losing data and maybe a second drive depending on which drive fails. Because of that, I want to move to raid z2 to ensure I can lose 2 drives without data loss. I’m going to move data from my 4x8TB drives, to the 3x10TB, reconfigure the 4x8TB, and move everything back. I run Immich, plex/jellyfin, and navidrome off the pool. All other documents are basically there for storage just in case. What options should I use for raid z2 when setting it up?

Make sure you scrub weekly. The probability of a second device failure is higher than you think, since it can be triggered by resilvering. I would also make sure you have a spare at hand.

For context, I’ve also been using ZFS since Solaris.

I was wrong about compression on datasets vs pools, my apologies.

By “almost no impact” (for compression), I meant well under 1% penalty for zstd, and almost unmeasurable for lz4 fast, with compression efficiency being roughly the same for both lz4 and zstd. Here is some data on that.

Lz4 compression on modern (post-haswell) CPUs is actually so fast, that lz4 can beat non-compressed writes in some workloads (see this). And that is from 2015.

Today, there is no reason to turn off compression.

I will definitely look into the NFS integrations for ZFS, I use NFS (exports and mounts) extensively, I wonder what I’ve been missing.

Anyway, thanks for this.

They banned the user that did the robust cybersecurity audit. They banned everyone who pointed it out or linked to the post or mentioned it. They took the subreddit private. The clown dev has a donate feature and claims that it will be used to put his daughter through school. Just scum all around.

Personally I prefer my software to give me options, I hate when stuff like this is picked for me when equally valid options exist

My current internet setup is like this (which is common for most people).

fiber line from ISP <-> ISP fiber modem <-> Personal wifi router <-> switch

This is working fine with no issues. But I need to power two devices. I want to reduce this to a single device.

fiber line from ISP <-> Modem+Firewall PC <-> Switch <-> AP1,AP2...

From my initial research, what I need is an SFP module which can be attached to a PC which supports SFP. OPNsense should be able to handle most SFP modules.

What is the community’s take on this? Is this worth the effort? Can I find a mini-PC which supports SFP? Will it be cost effective?

Older 10G SFP+ models were definitely power hungry. I think they’ve gotten better since then, but I haven’t really looked into how much better.

Yeah. I ended up getting a couple ms of latency back when i pulled the isp router too.

Hi everyone,

For those of you scaling up your NAS or Data Center in 2026, sourcing high-capacity drives like the 26TB and 28TB Enterprise models often comes with a painful 20% import tax hit in Europe.

At RobertElectronics, we’ve optimized our logistics to provide factory-recertified drives with a full 5-year warranty, matching factory standards while bypassing the typical tax traps through DDP (Delivered Duty Paid) routes.

Explore our inventory with precise technical specs and localized support:

Global / USA: [https://www.robertelectronics.com/]()

United Kingdom: https://www.robertelectronics.co.uk/

France: https://www.robertelectronics.com/fr

Why 26TB/28TB Recertified? Our drives undergo a rigorous multi-stage recertification process to ensure zero-hour reliability. You can find our full technical whitepaper and TCO analysis on our GitHub Documentation.

These prices are terrible, even for Europe.

Recertified drives are about the same as used cars with odometers reset to zero.

What kind of idiot would buy them?

I set up a quick demonstration to show risks of curl|bash and how a bad-actor could potentially hide a malicious script.

It’s nothing new or groundbreaking, but I figure it never hurts to have another reminder.

Hahahaha noticed this too. 1.5 was where it was at tho

I think the general response is from confusion over what you could possibly have been using the url bar for in your browser if you didn’t know you could put urls there.

PodOsef is an MP3-first podcast publishing system: drop MP3s into a folder, it generates HTML + RSS. No DB, the MP3 metadata is the source of truth. Also supports an archive mode that watches a main feed and mirrors episodes. Repo + write-up:

Thank you.

After feedback on artwork, one of my friends gave me new artwork for the podOsef. I updated the post and source code.

You should have all kinds of options on Lemmy… You can edit a post and change it to whatever you like. Or delete it and optionally post a new one…

Thank you, I’ll delete and report.

Hey all,

I’m setting up a homeserver and trying to figure out the best way to access it remotely. I’ve been looking at different solutions, but I’m a little stuck.

I’ve been looking at VPNs, but it feels weird, to route everything through my home IP when I’m also trying to use a commercial VPN for privacy / to combat services fingerprinting me based on my IP.

I’m currently considering a reverse proxy setup with an authentication provider like authentik or authelia, but as far as I understand, that wouldn’t work well with accessing services through an app on my mobile device (like for jellyfin music for example.) I did think about just opening up the ports and using a DDNS with a reverse proxy, but is’nt that like a big security risk?

Keep in mind I am no network admin, but I don’t have anything against learning if someone can point me in the right direction.

Also I heard some people say that on proxmox you should use unprivileged containers instead of vms for your services, does that hold up?

Any recommendations for tools or approaches?

That’s a bummer. It’s great for this stuff, don’t need processing power or memory, and I don’t really care if it got nuked for some reason

This is the best option if you don’t want to manage your own VPN server.
