If VMs are not created in an LXD cluster

If VMs are not created in an LXD cluster

In some cases, virtual machines in an LXD cluster are not created because there are no root datasets in the ZFS pool.

Diagnostics

  1. Connect to the server with the ZFS storage via SSH.

  2. Enter the command: 

    zfs list

    Examples of responses for the zfs0 pool:

    Root datasets are created

Solution

If there are no root datasets in the pool, create them manually:

  1. Connect to the server with the ZFS storage via SSH.

  2. Run the commands: 

    zfs create -o mountpoint=legacy zfs0/containers
zfs create -o mountpoint=legacy zfs0/custom
zfs create -o mountpoint=legacy zfs0/deleted
zfs create -o mountpoint=legacy zfs0/deleted/containers
zfs create -o mountpoint=legacy zfs0/deleted/custom
zfs create -o mountpoint=legacy zfs0/deleted/images
zfs create -o mountpoint=legacy zfs0/deleted/virtual-machines
zfs create -o mountpoint=legacy zfs0/images
zfs create -o mountpoint=legacy zfs0/virtual-machines
