Hi,
We have a FAS 2552 which I have created two aggregates on of 4.77TB. On one of these aggregates I have a Volume which is 700GB which is thick provision and no snapshots or fractional reserve 0%. I present this to a LUN and then a ESXi platform. I create one thick provision VM disk of 450GB.
At this point the LUN shows 450GB in use. Then I lay 450GB of data down and I do this a couple of times. Then the LUN goes offline and the Volume is at 100%! Deleting the data in the drive doesn't seem to fix this. So the LUN is up and down.
Why is this ? I'm confused as the drive is thick provisioned as is the Volume. So I should only ever be using max 450GB! No snapshots.
I would say this is Monday morning blues but I was looking at this problem on Friday and I have done all the documentation and training videos..... I could have forgot the reason for this issue as I did all the calculations in the spring 🙂 But then if I was right in my understanding this wouldn't be happening.....
Thanks
Ed
