During thin pool creation if user does not specify anything for the low water mark thresold, it would result in 0 and no events will be generated when thin pool capacity is reaching its full size. IMHO, if user does not specify anything during thin pool creation, we can assume some value something like 25%, so that when a thin pool is consumed more than 75%, there will be an event generated for that pool. I am not sure what should be the default low water threshold percentage. Is there any recommended value for low water threshold value in dm thin pools? Regards, M.
