Abstract:
A block-based storage system may implement page cache write logging. Write requests for a data volume maintained at a storage node may be received at a storage node. A page cache for may be updated in accordance with the request. A log record describing the page cache update may be stored in a page cache write log maintained in a persistent storage device. Once the write request is performed in the page cache and recorded in a log record in the page cache write log, the write request may be acknowledged. Upon recovery from a system failure where data in the page cache is lost, log records in the page cache write log may be replayed to restore to the page cache a state of the page cache prior to the system failure.

Claim (Index 7):
The method of  claim 5 , wherein the storage node is one of two or more storage nodes that maintain replicas of the data volume, wherein at least one of the two or more storage nodes different than the storage node does not maintain a respective page cache write log for write requests with respect to the data volume.
