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 9):
The method of  claim 5 , further comprising:\n detecting a trim event for the page cache write log; in response to detecting the trim event:\n identifying a trim location in the page cache write log; \n performing one or more flush operations to write at least some of the plurality of page cache entries from the system memory to the at least one block-based storage device; and \n upon completion of the one or more flush operations, reclaiming one or more portions of the persistent storage device maintaining the page cache write log for storing additional log records describing updates to the page cache.
