btrfs + snapraid: good idea for homelab? (feddit.de)

Hi!

I'm about to upgrade my homelab from a RAID1 with two 8TB drives to a new one with two additional dives. I mostly use my homelab for Nextcloud (Documents, photos, audiobooks, ...), media storage, jellyfin and whatever docker container I think would be cool to self host.

Since data availability is less of an issue for me and Backup Space is limited, I'm thinking of ditching the RAID in favour of btrfs and for additional safety: use one of my 8TB drives as a Snapraid parity drive. At least for the personal nextcloud data - I can get the media files from elsewhere in case of data loss.

However, tutorials of btrfs with Snapraid are a bt thin on the ground and with this being my first time using btrfs, I'm a bit hesitant. Some people suggest MergerFS with btrfs + snapraid, but I fail to see the advantage of MergerFS with btrfs.

So... is this actually a good Idea? It seems to me that this would be a good tradeoff and I could wait a bit before the next time I need to buy a storage upgrade.

Thanks in advance. :)

I tinkered with the same idea when I built my Nas a few years back. Decided against it and went with raidz2.

Let me know if you go for it and it works!

Side note: I'll be updating my lab to rancher harvester W/ k8s this weekend, so I'll be using Longhorn for storage. Should be interesting!

Rancher is pretty great! The (basically) one-click install made life really easy for getting K8s setup, and storage just worked with longhorn, which was nice.

How'd your migration go? What's your cluster look like, hardware wise?

Unfortunately a bad patch panel set me back. A new one is on its way!

Ah, that's unfortunate, but at least a new one is on the way lol
