v2 volume sanity check

https://longhorn.io/docs/1.10.0/v2-data-engine/features/

Tests Prerequisite

  • Load the kernel modules on the each Longhorn node 
    modprobe uio
modprobe uio_pci_generic
modprobe vfio_pci
modprobe nvme-tcp

Test Items

1. Support both AMD64 and AMD64

2. Block disk management

3. Orphaned replica management

Creating a v2 Orphan Replica in Longhorn

  1. Execute the go-spdk-helper Command in the Instance Manager Pod:

    • Use the following kubectl command to execute the go-spdk-helper tool directly within the specified instance manager pod. This command will create a new logical volume (LVOL) in the desired logical volume store (LVSTORE).
    • Command syntax: 
      kubectl -n longhorn-system exec -it <instance-manager-pod-name> -- /bin/bash -c "go-spdk-helper lvol create --lvs-name <DISK_NAME> --lvol-name <LVOL_NAME>-r-xxxxxxxx --size <LVOL_SIZE_IN_MIB>"
    • Replace the placeholders with your specific values:
      • <instance-manager-pod-name>: The name of your instance manager pod.
      • <DISK_NAME>: The name for the disk on the node.
      • <LVOL_NAME>: The name of the volume where the replica will be created.
      • <LVOL_SIZE_IN_MIB>: The size of the logical volume in MiB.

  2. Example:

    • Here’s an example where an LVOL named test001 is created in the LVSTORE disk-2 with a size of 12400 MiB: 
      kubectl -n longhorn-system exec -it instance-manager-cddd0dac94705fc3e267c2e157224257 -- /bin/bash -c "go-spdk-helper lvol create --lvs-name disk-2 --lvol-name test001-r-xxxxxxxx --size 12400"

  3. Verify the Creation:

    • After executing the command, you should receive a JSON output similar to the following: 
      {
    "alias": "disk-2/test001-r-xxxxxxxx",
    "uuid": "f4fa5b01-5171-4eaf-bf46-e62ea7236784"
}
    • This output confirms that the LVOL was successfully created with the specified alias and UUID.
