1. A method for handling storage in a virtualization environment, comprising:
identifying a situation in which a storage controller ownership change is to occur for a virtual disk that is managed by a storage controller in a first node that hosts one or more virtual machines, identifying a candidate replacement owner for the virtual disk by performing a leadership election among a plurality of volunteer storage controllers, wherein a volunteer storage controller of the plurality of volunteer storage controllers is elected as the candidate replacement owner, wherein the volunteer storage controller is a storage controller in a second node that hosts one or more virtual machines, wherein the second node is different from the first node; and transferring ownership of the virtual disk to the candidate replacement owner, wherein after the transfer the virtual disk is managed by the storage controller in the second node.
