M____U was the one that I made up that only was 120gigs or so. So I made up a new share and turned the cache off since what i understood from everyones post is the cache is used as part of a share, and by not using the cache it would make the share use the rest of the space on the array instead of limiting itself to what was left of the cache.
so I deleted M_____U made up a new one called M_____E and when i turned off the cache this time making up the share it used the 15 TB instead of the 120g
Still doesnt make sense to me why it would operate that way but from what I read in the post thats what I understood you all to say Still dont understand why you can set you own size based on space left in the array seems to make more sense to me than just have the system assign a size to a share, but thank you for taking a look and helping Here is the diagnostics
