cozystack-blockstor

Development stand and integration tests for a Go reimplementation of LINSTOR.

What's here

• stand/ — scripts to bring up a 3-node Talos cluster on QEMU/KVM with DRBD, install Piraeus operator + linstor-csi, and (optionally) the Java LINSTOR controller for contract-diff testing.
• tests/ — smoke tests against a running stand.
• docs/ — design notes.

Requirements (host)

• Linux x86_64 with KVM enabled (/dev/kvm accessible)
• talosctl, kubectl, helm, qemu-system-x86_64
• DRBD9 kernel module loaded on host (modprobe drbd)
• ~8 GB free RAM and ~20 GB disk per cluster

Quick start

# Single cluster (default name "blockstor")
make up
make piraeus
make smoke
make down

# Multiple parallel clusters
make up      NAME=alice
make up      NAME=bob
make piraeus NAME=alice
make piraeus NAME=bob
make smoke   NAME=alice
make smoke   NAME=bob
make down    NAME=alice
make down    NAME=bob

Each cluster gets its own talos+kube config under .work/<NAME>/.

Selecting a stand from your shell

eval "$(make use NAME=alice)"
kubectl get nodes
