Lock reservations for shared storage

A system comprising:

• a memory comprising instructions;
• and
• a processor coupled to the memory;
• the processor configured to execute the instructions to cause the processor to perform operations comprising:
• translating a storage reserve command formatted according to a storage protocol to a lease acquire command formatted according to an object store protocol, the storage reserve command generated by a first node to reserve a storage structure associated with an object of an object store of a cloud computing environment, and wherein the lease acquire command includes a first lease identifier identifying the first node;
• transmitting the lease acquire command to the object store to obtain a lease associated with the first lease identifier to grant the first node exclusive write access to the object and prevent a second node from writing to the object based on the lease being associated with the first lease identifier;
• transmitting a change command to the object store to change the lease from being associated with the first lease identifier to being associated with a second lease identifier of the second node to grant the second node exclusive write access to the object and prevent the first node from writing to the object while the lease is associated with the second lease identifier;
• in response to the first lease identifier in the change command not matching a current lease identifier assigned to the object, generating a break lease command;
• and
• routing the break lease command to the object store to break the lease.

A non-transitory machine-readable medium comprising instructions for performing a method, which when executed by a machine, causes the machine to perform operations comprising:

• translating a storage reserve command formatted according to a storage protocol to a lease acquire command formatted according to an object store protocol, the storage reserve command generated by a first node to reserve a storage structure associated with an object of an object store of a cloud computing environment, and wherein the lease acquire command includes a first lease identifier identifying the first node;
• transmitting the lease acquire command to the object store to obtain a lease associated with the first lease identifier to grant the first node exclusive write access to the object and prevent a second node from writing to the object based on the lease being associated with the first lease identifier;
• transmitting a change command to the object store to change the lease from being associated with the first lease identifier to being associated with a second lease identifier of the second node to grant the second node exclusive write access to the object and prevent the first node from writing to the object while the lease is associated with the second lease identifier;
• in response to the first lease identifier in the change command not matching a current lease identifier assigned to the object, generating a break lease command;
• and
• routing the break lease command to the object store to break the lease.
