Lock state reconstruction for non-disruptive persistent operation

A storage node for use within a storage cluster, the storage node comprising:

• a memory containing a machine-readable medium that comprises machine-executable code having stored thereon instructions for performing a method;
• and
• a processor communicatively coupled to the memory, the processor configured to execute the machine-executable code to cause the processor to:
• reconstruct a lock data structure representing a lock for a data container, based on a mirrored lock data structure representing the lock, the mirrored lock data structure being stored at a different storage node, the storage node and the different storage node together forming a high-availability pair within the storage cluster,
• set a flag associated with the lock data structure, wherein the flag indicates that the lock data stricture has been recently constructed;
• receive, subsequent to reconstructing the lock data structure, a data operation request permitted by the lock from a client to operate on the data container,
• determine that the received data operation request involves the data container for which the lock data structure has been reconstructed by determining whether the flag associated with the lock data structure exists, and
• instruct the client to terminate a connection between the storage cluster and the client in response to determining that the lock data structure representing the lock has been reconstructed based on the flag indicating that the lock data structure has been recently reconstructed.

A non-transitory machine-readable medium having stored thereon instructions for performing a method, the instructions comprising machine-executable code that, when executed by one or more machines, causes the one or more machines to perform operations comprising:

• reconstructing, at a storage node of a storage cluster, a lock data structure representing a lock for a data container, based on a mirrored lock data structure representing the lock, the mirrored lock data structure being stored at a different storage node, the storage node and the different storage node together forming a high-availability pair within the storage cluster;
• setting a flag associated with the lock data structure, wherein the flag indicates that the lock data structure has been recently constructed;
• receiving a data operation request permitted by the lock from a client to operate on the data container subsequent to reconstructing the lock data structure;
• determining that the received data operation request involves the data container for which the lock data structure has been reconstructed by determining whether the flag associated with the lock data structure exists;
• and
• instructing the client to terminate a connection between the storage cluster and the client in response to determining that the lock data structure representing the lock has been reconstructed.
