liqoctl move

Move an object to a different cluster

Description

Synopsis

Move an object to a different cluster.

liqoctl move volume

Move a Liqo-managed PVC to a different node (i.e., cluster)

Synopsis

Move a Liqo-managed PVC to a different node (i.e., cluster).

Liqo supports the offloading of stateful workloads through a storage fabric leveraging a custom storage class. PVCs associated with the Liqo storage class eventually trigger the creation of the corresponding PV in the cluster (either local or remote) where its first consumer (i.e., pod) is scheduled on. Locality constraints are automatically embedded in the resulting PV, to enforce each pod to be scheduled on the cluster where the associated storage pools are available.

This command allows to move a volume created in a given cluster to a different cluster, ensuring mounting pods will then be attracted in that location. This process leverages Restic to backup the source data and restore it into a volume in the target cluster.

Warning

only PVCs not currently mounted by any pod can be moved to a different cluster.
