Abstract

Various systems and methods for performing write-back caching in a cluster. For example, one method can involve a first node detecting that no failover nodes are available. A determination is made whether the first node should use write-back caching or not. If the first node is to continue using write-back caching, a first local cache identifier and a global cache identifier are both updated.
