US Patent 10282263 Creating distributed storage during partitions

A system and method are provided for processing to create distributed volume in a distributed storage system during a failure that has partitioned the distributed volume (e.g. an array failure, a site failure and/or an inter-site network failure). In an embodiment, the system described herein may provide for continuing distributed storage processing in response to I/O requests from a source by creating the local parts of the distributed storage during the failure, and, when the remote site or inter-site network return to availability, the remaining part of the distributed volume is automatically created. The system may include an automatic rebuild to make sure that all parts of the distributed volume are consistent again. The processing may be transparent to the source of the I/O requests.
