Patent attributes
Techniques for implementing dynamic base disk mirroring for linked clones are provided. In one set of embodiments, a first node in a distributed storage system can monitor a congestion level of a base disk residing on the first node, where the base disk is shared by a plurality of linked clones. Upon determining that the congestion level exceeds a threshold, the first node can send, to a second node, a request to create a mirror of the base disk on that second node. Upon receiving an acknowledgement from the second node that the mirror has been successfully created, the first node can update a mirror set associated with the base disk to include an entry identifying the mirror. The first node can then communicate the updated mirror set to one or more other nodes.
