Longhorn overkill for RAID ? - eviltoast

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 !

    I’m actually swapping from longhorn to rook and ceph right now. Longhorn has given a lot of troubles and it does not like replica of 1 at all. Sounds like you do want a NAS, though high availability is probably over kill for home use, having a NAS makes you have that as a single point of failure. I ended up upgrading all my nodes and keeping replication off 3 since I still wanted the high availability.

      I would guess it doesn’t like replica at 1 indeed.

      And using a NAS would be a single point of failure indeed, but how I’m using Longhorn right now already is (my storage node goes down, my cluster would be unstable)

      Thanks !
