> DMERR("unable to shrink cache due to dirty blocks"); Also, what is the process to recover from this error, given that you have already lost the end of the device and you cannot now resume the device without a preresume failure? Do the tools support retrieval of the dirty blocks from the portion of the device that you do still have?
