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 2):
The system of  claim 1 , wherein the storage node is further configured to:\n upon recovery from a system failure:\n obtain from the persistent storage device maintaining the page cache write log, the log record and the plurality of log records; and \n apply the log record and the plurality of log records maintained in the page cache write log to write to the page cache a state of the page cache prior to the system failure.
