Abstract: Generally described, one or more aspects of the present application correspond to a highly distributed replica of a volume stored in a networked computing environment. First and second replicas of the volume can be synchronously replicated, and some implementations of the tertiary replica can be asynchronously replicated. The highly distributed nature of the tertiary replica supports parallel data transfer of the data of the volume, resulting in faster creation of backups and new copies of the volume.

Abstract: Generally described, one or more aspects of the present application correspond to a highly distributed replica of a volume stored in a networked elastic computing environment. First and second replicas of the volume can be synchronously replicated, and some implementations of the tertiary replica can be asynchronously replicated. The highly distributed nature of the tertiary replica supports parallel data transfer of the data of the volume, resulting in faster creation of backups and new copies of the volume.

Abstract: A failure of a storage device used to provide a mirrored storage volume can be managed without a full re-mirroring of the volume. The volume can be provided using a set of similar storage devices on each of a master server and a slave server, and a technique such as data striping can be used to store the data for the volume across the various devices. When a storage device becomes unavailable, the data from the corresponding storage device on the other mirrored server can be written to the remaining storage devices on the server experiencing the device failure. The data interface can be virtualized such that the user can continue to send input and output (I/O) requests using the same address information. A translation layer can map the virtualized addresses to the physical addresses where the data is stored.

Abstract: A block-level data storage system receives a request to delete a data storage volume. As a result, the data storage volume is deleted and the areas comprising the volume are released and reaped. The areas may contain non-zero data within a plurality of data storage chunks that comprise the areas. An area cleaner is configured to zero out the areas for allocation to a newly created data storage volume.

Abstract: A distributed system may implement dynamic resource creation for connecting resources. Resource creation requests may be received for resources which are accessed by other resources hosted in a distributed system. An intention for the creation request is stored to perform the creation request. At a subsequent time, a request to connect another resource to the resource of the creation request is received. An infrastructure locality for the other resource may then be identified and utilized to determine a placement location for the resource. The resource may then be created at the placement location according to the stored intention. The resource may then be connected with the other resource for access.

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.

Abstract: A data storage system includes a head node and mass storage devices. The head node is configured to flush data stored in a storage of the head node, based at least in part on one or more triggers being met, from the storage of the head node to a set of the mass storage devices of the data storage system. The flushed data is written to a segment of free storage space across the set of the mass storage devices allocated for the given data flush operation. In some embodiments, a head node may flush both current version data and point-in-time version data to the set of mass storage devices. Also, the data storage system maintains an index that indicates storage locations of data for particular portions of a volume before and after the data is flushed to the set of mass storage devices.

Abstract: A user can set or modify operational parameters of a data volume stored on a network-accessible storage device in a data center. For example, the user may be provided access to a data volume and may request a modification to the operational parameters of the data volume. Instead of modifying the existing data volume, the data center can provision a new data volume and migrate data stored on the existing data volume to the new data volume. While the data migration takes place, the existing data volume may block input/output (I/O) requests and the new data volume may handle such requests instead. If a request is received for data not yet migrated to the new data volume, then the new data volume prioritizes a migration of the requested data.

Abstract: Write optimization for block-based storage performing snapshot operations may be implemented. Write requests for a particular data volume may be received for which a snapshot operation is in progress. A determination may be made as to whether a data chunk of the data volume modified as part of the write request has not yet been stored to a remote snapshot data store as part of the snapshot operation. For a data chunk that is to be modified and that has not yet been stored, the data chunk may be stored in a local in-memory volume snapshot buffer. Once the data chunk is stored in the in-memory volume snapshot buffer, the write request may be performed and acknowledged as complete. The data chunk may be sent to the remote snapshot data store asynchronously with regard to the acknowledgment of the write request.

Abstract: The relative health of data storage drives may be determined based, at least in some aspects, on data access information and/or other drive operation information. In some examples, upon receiving the operation information from a computing device, a health level of a drive may be determined. The health level determination may be based at least in part on operating information received from a client entity. Additionally, a storage space allocation instruction or operation may be determined for execution. The allocation instruction or operation determined to be performed may be based at least in part on the determined health level.
