Longhorn overkill for RAID ? (lemmy.world)

Hello selfhosted !

Continuing my journey of setup up my home k3s cluster.

I’ve been asking myself if Longhorn might be overkill for my home cluster,here’s what i did:

3 machines running k3s each. One of them has a storage in Raid 5 and I dont want to use any storage from the other two.

Thing is, i had to configure replicas to 1 in longhorn for my pv to be green.

Hence my question, since data is already replicated in the array, shouldn’t I just use a NFS storage class instead?

Thanks !

You are completely right.

However in my mind (might be wrong here) if I use another node, i wouldn’t use the RAID array completely.

While setup up i thought that its either:

  • NAS storageClass attached to the RAID array, no longhorn
  • with longhorn when there is no RAID, but replication at 3

In either case, the availability of my data would be quite the same right ?

(Then there is options to backup my PV to s3 with longhorn and all that i would have to setup again though )

Thanks for your answer !
