Disk Setup

[Space01]

Hey Guys,

I would love a recommendation on how to set up the available disks in a smart way.

- 2x 18TB Exos 2X18 Seagate HDD
- 1x 500GB Samsung 870 EVO SATA SSD

I plan on using it for a Mediaserver so just movies and shows. Im unsure if zfs is worth it because I dont see a usecase right now for RAID and I just wanted some sort of JBOD.

I thought about just making a 36TB Pool of the HDDs and Proxmox is installed on the SSD aswell as the VMs/LXCs .
Can I then just mount the HDD Pool into my VM so Jellyfin for example is able to see the files on there?

Please give me your opinion about how I should set it up.

ZFS can do jbod/raid0 in one pool of course. That's just striped vdevs with a single disk each. Most features will work nevertheless.

I will never recommend a non-redundant vdev, but dropping ZFS completely would also not be an option - for me!

18TB Exos

If you bought these as new, you might want to check them first. Here in Germany there is some bigger fraud with Exos models going on (used disks sold as new), they got anyhow into the supply chain of trusted shops.

tldr; Check with smartctl -a /dev/sdX vs smartctl -l farm /dev/sdX
If the (low) hours are plausible all good, if not: refund.

Don't do this. You double the failure rate of the pool, it is worse than using a single disk. If one disk dies, the whole pool is gone!

The only smart option here is a mirror. For smarter options you need much more disks.

Even though im from Germany I bought them refurbished and they are fine.

But I want as much capacity as possible, thats why I dont mind.

Mache ich auch so, ich hab lieber billigere Platten gebraucht, aber dafür mehr Redundanz (+Backup)...was dann meine eigene Garantie ist.

Wenn du weißt, worauf du dich mit raid0 einlässt, dann kannst du es natürlich machen. Sehr regelmäßiges Backup ist dann natürlich Pflicht.

I do the same, I prefer cheaper disks, but with more redundancy (+backup)...which is then my own guarantee.

If you know what you're getting into with raid0, then of course you can do it. Very regular backups are of course a must.

The Problem is, i wanted to do thatt too a moment ago BUT proxmox just provides smartctl 7.3 and the -l farm option i getting into smartctl in version 7.4....
so i would really like to see that proxmox provides these version...
