摘要： A method for managing replication of cloned files is provided. Embodiments include determining, at a source system, that a first file has been cloned to create a second file. Embodiments include sending, from the source system to a replica system, an address of the first extent and an indication that a status of the first extent has changed from non-cloned to cloned. Embodiments include changing, at the replica system, a status of a second extent associated with a replica of the first file on the replica system from non-cloned to cloned and creating a mapping of the address of the first extent to an address of the second extent on the replica system. Embodiments include creating, at the replica system, a replica of the second file comprising a reference to the address of the second extent on the replica system.

摘要： The described technology is generally directed towards replicating a filesystem namespace from a source system such as a source node cluster to a target system such as a target node cluster. Directory transfer tasks processed at the source are sent to the target build a replica of a hierarchical namespace on a target cluster, in which the namespace contains the directories and files, with the file content temporarily absent. Files transfer tasks processed at the source are sent to the target to write the content into the files, generally after namespace creation is complete. Directory transfer is recursive, as one directory transfer task creates another directory transfer task for each of its child directories, and can be concurrent and sent as bulk transfer requests for efficiency in reducing overall latency overhead. File content transfer can transfer the content of multiple small files in a single transfer task request.

摘要： Techniques for database replication include a method performed by at least one hardware processor of a resource management node. The method includes detecting a request that a database instance of a database stored at a first network deployment is available at a second network deployment. Responsive to the request, the second network deployment is provisioned with a plurality of data objects. A first data object of the plurality of data objects includes a database shell. The database shell is reconfigured as the database instance of the database based on pushing data of the database into the database shell. Access to the database instance at the second network deployment is authorized based on at least a second data object of the plurality of data objects.

摘要： Provided herein are systems and methods for replicating share objects to remote deployments. An example method includes creating a share object for a first deployment of a data sharing platform. The share object includes share object metadata that describes access privileges in the first deployment. The method also includes creating, in a second deployment of the data sharing platform, a replica of the share object. The replica determines access privileges in the second deployment. The method also includes receiving, at the first deployment, a refresh message from the second deployment. The method also includes, in response to receiving the refresh message, transmitting the share object metadata from the first deployment to the second deployment and updating, by a processing device, the replica based on the share object metadata.

摘要： Managing storage systems that are synchronously replicating a dataset, including: detecting a change in membership to the set of storage systems synchronously replicating the dataset; and applying one or more membership protocols to determine a new set of storage systems to synchronously replicate the dataset, wherein the one or more membership protocols include a quorum protocol, an external management protocol, or a racing protocol, and wherein one or more I/O operations directed to the dataset are applied to a new set of storage systems.

摘要： A storage network operates by: sending a slice verification request to a destination storage unit, wherein the slice verification request includes a nonce and one or more of: a slice identifier, the slice, a revision indicator, or a verification method indicator; receiving an integrity value from the destination storage unit; determining when the integrity value is verified by determining one of: when a hash of the slice and the nonce matches the integrity value; when a decrypted signature of the integrity value matches a hash of the slice and the nonce; or when the decrypted signature of the integrity value matches the slice and the nonce; and when the integrity value is verified, updating a slice assignment corresponding to the slice, wherein updating the slice assignment associates the destination storage unit with the slice and disassociates the source storage unit from the slice.

摘要： Techniques are described for checkpointing multiple key ranges in parallel and concurrently during file storage replications between file systems in different cloud infrastructure regions. In certain embodiments, multiple range threads processing multiple key ranges, one thread per key range, create checkpoints for their respective key ranges in parallel and concurrently after processing a per-determined number of B-tree keys. In certain embodiments, each thread requests a lock from a central checkpoint record and takes turns for updating a status byte while continuing processing the B-tree keys in its responsible key range. In certain embodiments, upon encountering a failure event, either a system crash or a thread failure, each thread restarts its B-tree key processing from a B-tree key after the most recent checkpoint.

摘要： In some examples, a data management system processes snapshots of a distributed file system, the distributed file system having files, each file comprising multiple data chunks. The data management system performs operations including storing file-to-chunk mapping in file system metadata; creating, for each chunk, a chunk generation ID by associating each chunk with a file system generation ID; in a next-generation snapshot of the distributed file system, incrementing, for all chunks in the next-generation snapshot, the respective chunk generation IDs; and taking a snapshot of the file system metadata and storing an updated file-to-chunk mapping associated with the next-generation snapshot.
