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 13):
The method of  claim 5 , wherein the storage node is one of a plurality of storage nodes implementing a network-based block-based storage service, wherein the write request is received from a virtual compute instance implemented by a network-based virtual compute service, wherein the network-based block-based storage service and the network-based virtual compute service are implemented together as part of a same network-based services provider network.
