ACFS-05951：snapshot creation is blocked while ACFS replication is updating the standby

解决方法：If the command has completed in the meantime, no action is required. Otherwise, if no action is taken, snapshot creation will be retried periodically and complete once the ACFS replication update has completed. To complete the snapshot creation immediately, interrupt the replication update and reissue the command. Terminiate the 'acfsutil snap create', run 'acfsutil repl pause' on the replication primary to pause the update, and then reissue 'acfsutil snap create'. Finally, run 'acfsutil repl resume' on the primary to resume the replication update.
