[lxc-users] cluster node with different storage config

[Aleksandar Ivanisevic]

Hi,

I’m trying to join a node to a lxd cluster that has different storage configuration. My cluster uses storage pool ‘local’ in zfs pool ‘ee’ and the new node uses ‘rpool/lxd’. Although the documentation (https://linuxcontainers.org/lxd/docs/master/clustering.html) suggests that should be possible, no matter what I put in the preseed yaml it always either tries to import the zfs pool ‘ee’ or create an already existing pool ‘local'

Does anyone know what is the correct syntax or is it possible at all?

$ lxd init --preseed < /tmp/cluster.yaml
$ cat /tmp/cluster.yaml
cluster:
  enabled: true
  server_name: ${HOSTNAME%%.*}
  server_address: ${HOSTNAME%%.*}:8443
  cluster_address: lxd1:8443
  cluster_certificate: "-----BEGIN CERTIFICATE——
...
-----END CERTIFICATE-----
"
  cluster_password: “..."
  member_config:

# no matter what i put after this line it is always the same errors
# Error: Failed to join cluster: Failed to initialize member: Failed to initialize storage pools and networks: Failed to create storage pool 'local': Storage pool directory "/var/snap/lxd/common/lxd/storage-pools/local" already exists
# or, if the new member’s local pool is not called ‘local’ then it complains about zpool import ‘ee’ failed.

 
  - entity: storage-pool
    name: cluster
    key: source
    value: "rpool/lxd"
    key: zfs.pool_name
    value: "rpool/lxd"
