Current behavior

https://linuxcontainers.org/incus/docs/main/howto/storage_create_instance/#move-instance-storage-volumes-to-another-pool indicates that this can be done:

incus move <instance_name> --storage <target_pool_name>

However, this fails with the error:

# incus move athena --storage styx
Error: Migration API failure: Storage pool can be specified only together with target flag

Meanwhile:

root@hercules:~# incus cluster list
Error: Server isn't part of a cluster

So, the method to move an instance from one storage pool to another, while the Incus host is not clustered, is not obvious.

Migration API assumes Incus host is always clustered.

Expected behavior

Migration API should work when the Incus host is not clustered

Steps to reproduce

  1. Create Incus host (non-clustered)
  2. Create 2 storage pools
  3. Create instance in first storage pool
  4. Attempt to move instance to 2nd storage pool
