Be aware that doing it like this, the traffic from the VPS to your home will be unencrypted.


The issue is that’s it’s too late… I already have my NAS. The only things I can optimize are the disks


Thanks, yes, I’m interested in the SSDs models!



Indeed, I haven’t thought about the W/TB. This is definitely something I’ll to consider, thanks!


With what I saw with me current HDDs I wouldn’t have though smaller HDD would be the most power efficient. And now I understand better why sometimes I read HDD can be more efficient than SSD.

Any brands/models you would recommend?


Recommendation for low power SSD
I’m trying to improve the power consumption of my NAS. The 2 (7200 rpm) HDDs I had were using 15W at idle and 5W when spun down. I’m reading a lot of conflicting information about what is lower power between HDD, SSD and NVMe SSD. Eventually I started looking at SATA SSD (please let me know if this is not the most power efficient) I found [this site](https://www.tomshardware.com/features/ssd-benchmarks-hierarchy) that shows a benchmark of different SSDs and their average power consumption. I was about to go with WD Red but then I found a YouTube video saying I shouldn’t go with WD for a NAS. Can you tell me what brand or model you’re using in your homelab that’s power efficient? Ideally I would like 4TB SSD. Thanks!

Thanks, this is really efficient. I now have good hopes that changing my PSU should bring me closer to this


This is amazing, thank you!

And now this confirms that my current PSU is terrible…


I planned to share it with my family. As I won’t be the only user, this is not ideal. Besides I run automatic backup and planned to also store them in the NAS. So again if it’s off half the time, this is not ideal.


Indeed, this seems to be the issue!

I’ve checked the PX-450 but it seems to be out of stock…

I’ll do more searches about PSU, thanks!


Thanks I’ll check this


Yes definitely. This is just that it was my first time assembling a PC. I had a bit of a hard time and I am not in a hurry to disassemble it 😅

That may change in a couple of days thought


I’m going to try to unplug these. But even if I remove 20W from the 2 HDDs, there are still 25W which seem a lot


I don’t know much about hardware. I used these suggestions: https://forums.serverbuilds.net/t/guide-nas-killer-6-0-ddr4-is-finally-cheap/13956

I built a NAS where I can put 6 HDDs, there are enough plugs on the PSU.

Do you think the PSU is the issue?


Thanks that would be cool. Also if you can tell me if this is a NUC or something larger.


I guess I’ll do this if I don’t find a way to reduce the power consumption


Unfortunately this is idling after boot. While booting it jumps to 70W and I haven’t seen it go below 45W idling…


I’m using an EVGA 500 W1


Thanks. So If I take 5W a disk, I may have 20W just from the disks.

There are still 25W remaining. For a low power CPU that looks like a lot 😕


I have checked but I haven’t seen anything about power. By any chances, do you know in what category it may be?


Optimize power consumption
So I have finally built my NAS. I used an N100 CPU because I saw it has low power consumption. Right now I have 2 NVMe SSDs and 2 HDDs. I have installed proxmox on the 2 SSDs as RAID1. I have not partitioned the HDDs yet, they are just plugged in and powered on. Just booting into proxmox, without any VMs or containers running, I am pulling 45W from the wall. This looks super high to me, and I’m afraid that starting to use the HDDs and running some VMs may double this… I don’t have much references, but I have an Odroid with an external self-powered HDD, it is using 5W. I have a raspberry pi 4 with an external HDD, the raspberry is pulling 3W and the HDD 3W. With these data, I was thinking I wouldn’t go over 20W. 45W is enormous and not something I can run 24/7, kind of a fail for a NAS… Have I done something wrong or is it just how much it’s supposed to pull? Edit: I have come across powertop. Using the auto tune, I was able to drop to 33-35W. I have unplugged the HDDs and dropped to 22W. I guess I cannot go lower, this may be because of the PSU or the 2 NVMe

Yes this is where I first heard of mergerfs/SnapRAID. But I didn’t realize this guide wasn’t using any software on top of Proxmox. I’ll read again, thanks!


Thanks, I’ll check ZFS again!


How do you manage your shares?


I was comparing Proxmox and Unraid. I had ruled out TrueNAS because it only supports ZFS. I was wrong about the RAM for ZFS, but another issue is that it doesn’t support different disk sizes


Indeed, it wasn’t clear that it was how it worked. That seems better than the cache/mover system from Unraid.

Another point as to why I didn’t consider ZFS, is that it only works with disks having the same capacities. As I will be adding disks over time, I think I will be wasting disk space


Ok thanks.

Do you use anything to manage disk failure?


Thanks I wasn’t sure if this was a possibility


Oh ok I wasn’t sure about this. But I think TrueNAS only supports ZFS and this would be an issue on my system


Thanks, I’ve seen Incus have an online demo, this is nice, I’ll give it a try.

For BTRFS, if I understand correctly, I can have a similar result as mergerfs if I use SINGLE. But as RAID5/6 is unstable it seems I would still need snapraid, or am I missing something?


Don’t I need mergerfs and snapraid with BTRFS?

Also it’s not clear what LXD/Incus replaces? Is it Promox or Promox + OMV?


Best OS for a NAS
Hey again! I’ve progressed in my [NAS project](https://derpzilla.net/post/362835) and I’ve chosen to go for a DIY NAS. I can’t wait for the parts to arrive! Now I’m a bit struggling to choose an OS. I am starting with 2x10To HDD + 1To NVMe SSD. I plan to use 1 HDD for parity and to add more disks later. I plan to use this server purely as a NAS because I will be getting a second more powerful server some time next year. But in the meantime, this NAS is a big upgrade over my rpi 4, so I will run some containers or VMs. I don’t want to go with TrueNAS as I don’t want to use ZFS (my RAM is limited and I’m not sure I can add drives with different sizes). I’ve read btrfs is the second best for NAS, so I may use this. Unraid seemed like the perfect fit. But the more I read about it, the more I wonder if I shouldn’t switch to Proxmox. What I like about Unraid is the ability to add a disk without worrying about the size. I don’t care much about the applications Unraid provides and since docker-compose is not fully supported, I’m afraid I won’t be able to do things I could have done easily with a docker-compose.yml I also like that’s it’s easy to share a folder. What I don’t like about Unraid is the cache system and the mover. I understand why the system works this way but I’m not a fan. I’ve asked myself if I needed instant parity for all my data and if I should put everything in the array. The thing is that for some of my data I don’t care about parity. For instance, I’m good with only backing up my application data and to have parity for the backup. For my tv shows I don’t care about parity nor backup while I want both for my photos. After some more research, I found mergerfs and snapraid. I feel that they are more flexible and fix the cache/mover issue from Unraid. Although I’m not sure if snapraid can run with only 2 disks. If I go with Proxmox I think I would use OpenMediaVault to setup shares. Is anyone using something like this? What are your recommendations? Thanks!

Ok, this is good to know!


On the N100, they say the max support is 16GB RAM. If you were looking for at least 32GB, it may not be an option anymore


Actually I wanted to have a NAS and another more powerful server. But this is because I thought NAS were some cheap basic servers… When I saw the price I thought I might as well have a single more powerful server doing NAS + transcoding. I haven’t made my mind up, I’ll check the Lenovo Tiny, thanks


Thanks, 30W while idling and 40W~ while in use seems really fine!


Indeed, this is something I need to take into account


Okay thanks, this is good to know!


I would have, but this is all about the power consumption. Getting an old PC, I’m afraid to be at least around 100W…


Thanks, as I said I’m bad with hardware, so I need to lookup what NVMe SSD actually are.

Can you tell me about the power consumption you get from your setup?


Thanks! I didn’t know about this website.

Edit: After checking it out. This is exactly what I was looking for!


Recommendation for NAS
I’m looking for some recommendations to improve my homelab. But first a bit of history to explain where I’m at and where I’m going. I currently have a super old Odroid C2 and a Raspberry Pi 4B. Everything is working great, but I’m missing two things in this setup: -The ability to transcode -A NAS Now a little bit about me, I’ve been using Linux for more than a decade, so I know how to do stuff, but when it comes to hardware, I have close to zero knowledge… So I was a bit surprised when I plugged 2 external HDDs on my rpi and it shutdown them after a few minutes. I found out that it was a power supply issue, so I did the first thing that came to my mind at this time: I bought another HDD with external power supply, to then find out that having a self powered and an external powered HDD would still fail (although it took longer). So now I know my mistakes, I should have gone with a NAS instead. I checked the Synology NAS and found out NAS are actually quite expensive. I’m looking for at least 4 bays. I’ve been looking at some DIY NAS, but I’m a bit lost. I found some builds using a Jonsbo N2 that seems cool but at the same time I’m reading the fans are always running at full speed and I’m afraid that the power consumption will skyrocket. So to sum up, I would like to have a NAS, ideally that can transcode and is low power. In the beginning, I wanted to have a NAS and a mini-PC that can transcode to replace my Odroid C2. But it seems the NAS are far more expensive than the mini PC. What are the recommendations here? -Synology (Can it transcode?) -A DIY (Jonsbo with an ITX board that can transcode) -A DIY (Jonsbo with an ITX board just powerful enough for a NAS) + a mini PC -Something else? My budget was 500€, but it seems I won’t be able to do much below 700€

Question about backup
Hey guys, I would like to setup some backups. I have a raspberry at home and 2 VPS’s. I’m trying to setup borgmatic on my raspberry to back it up and the 2 VPS’s but I’m not sure this can be done. Right now I’m looking to back up the raspberry and use rclone to mount one of the VPS and back it up. The issue is with the second VPS, it has MariaDB running and I can’t see how to back it up remotely (the port is not exposed publicly). I don’t find anything about tunneling in borgmatic. Am I forced to install borgmatic on the VPS to back it up? If I do this, how can I merge the back up with the other ones? Actually should I do this or have 3 separate borg repositories? Lastly, my raspberry uses rclone to push to S3 and I don’t want the keys to be accessible on the VPS’s, that’s why I’m trying to have borgmatic only on my raspberry. Thanks for your help!
