I'm still trying to grasp NetApp's storage technology, so my question might be dumb >(
This is the setup
aggrage with no snap reserve and a single volume
the volume is set to none space reservation, 100% frac.res.
a single lun is created on the volume
The storage is producing the expected behaviour: the volume size is not reserved from the Aggregate. As I pump data onto the LUN, the data is getting stored, and the aggregate shows increased USED capacity.
Now, I would expect that if I delete data from the LUN the Aggrage's used capacity should became smaller (it should get smaller). However this is not happening at all.
So when I upload 2gb to the LUN (from a windows box), the aggreagate used capacity shows 2gbs. When i delete the files from the LUN, the aggregate doesn't go back to 0.. it is still showing 2gb as occupied capacity. If I do this upload/delete sequences from the windows box, that aggregate gets bigger, and bigger...
So how can I reclaim that used and deleted space from the aggr?
I to am having the same issue, you would think there would be a process running in the back ground every hour or so to reclaim space. As well as other limitations with the OS i am learning. Not sure the OS is really mature enough yet. A work in progress. I migrated from a Dell Equallogics and management of that system is light years ahead of NetApp. LLAP
