I’m looking for storage classes for a multi node cluster. I’m currently using Longhorn and NFS, but I’m not happy with the performance. My cluster doesn’t have beefy nodes, so Ceph/Rook is out of the question (for now).

Nodes:

  1. 8 GB RAM, 4 cores VM, control plane. 256 GB SSD
  2. 4 GB RAM, 2 cores, control plane, currently cordoned. 128 GB SSD
  3. 8 GB RAM, 4 cores, ARM, control plane. 512 GB SSD
  4. 8 GB RAM, 4 cores. 256 GB SSD
  5. 16 GB RAM, 6 cores. 256 GB SSD + 1 TB HD
  6. RPi 4, 4 GB RAM. 128 GB SSD
