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:
- 8 GB RAM, 4 cores VM, control plane. 256 GB SSD
- 4 GB RAM, 2 cores, control plane, currently cordoned. 128 GB SSD
- 8 GB RAM, 4 cores, ARM, control plane. 512 GB SSD
- 8 GB RAM, 4 cores. 256 GB SSD
- 16 GB RAM, 6 cores. 256 GB SSD + 1 TB HD
- RPi 4, 4 GB RAM. 128 GB SSD
I’m currently using Piraeus / LINSTOR and am quite happy with it: https://github.com/piraeusdatastore/piraeus
Found a Reddit thread that says that LINSTOR has a lower CPU usage (which is my main gripe with Longhorn). Might as well try this and report back. Is there a good way to migrate PVs and PVCs?
Volsync
Thanks!
I can confirm that the resource usage is quite low indeed. I only used it with Nomad instead of Kubernetes, so I can’t comment on how to best migrate PVs and PVCs.
Thanks
