System and method for synchronization in a cluster environment

A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon which, when executed across one or more processors, cause at least a portion of the one or more processors to perform operations comprising:

• performing a copy sweep operation to a first range of data on a source storage device;
• determining that the copy sweep operation has failed;
• sending a message to suspend I/O operations to the first range of data;
• and
• retrying the copy sweep operation based upon, at least in part, determining that the copy sweep operation has failed, wherein the copy sweep operation is retried without receiving acknowledgement the I/O operations to the first range of data are suspended.

A computing system including one or more processors and one or more memories configured to perform operations comprising:

• performing, via a first computing device, a copy sweep operation to a first range of data on a source storage device;
• determining that the copy sweep operation has failed;
• sending a message to a second computing device to suspend I/O operations to the first range of data;
• and
• retrying the copy sweep operation based upon, at least in part, determining that the copy sweep operation has failed, wherein the copy sweep operation is retried without the first computing device receiving acknowledgement that the second computing device is suspending the I/O operations to the first range of data.
