1. A computer-implemented method, executed on a computing device, comprising:
defining a normal IO write mode for writing data to a storage system, the normal IO writing mode including:
writing the data to a cache memory system of a first storage node;
writing the data to a journal of the first storage node;
sending a notification concerning the data to a second storage node;
writing one or more metadata entries concerning the data to a journal of the second storage node;
in response to writing the one or more metadata entries concerning the data to the journal of the second storage node, sending an acknowledgment signal to the host device; and
writing the data from the cache memory system to the storage array;
receiving a request for the storage system to enter a testing IO write mode from the normal IO write mode; and
in response to receiving the request for the storage system to enter the testing IO write mode from the normal IO write mode:
writing the data to a cache memory system of the first storage node;
bypassing the writing of the data to the journal of the first storage node; and
in response to writing the data to the cache memory system, sending the acknowledgment signal to the host device.
