Abstract
A system and method are disclosed for providing journal recovery in a multi-node environment which comprises determining whether a block was last updated by a first node; determining whether the block is associated with a lock held by a second node; and writing the block to a final location if the block is not associated with a lock held by the second node. In another embodiment, a system and method are disclosed for providing journal recovery in a multi-node environment which comprises determining whether a block is associated with metadata; determining whether the block is associated with a lock held by a surviving node; and writing the block to a final location if the block is not associated with a lock held by the surviving node.
