Hi all
Please bear with me new user and my knowledge of NetApp is good but not expert 🙂
So in essence we are adding a new disk to one aggregate on our FAS2020, it contains about 20 flexvols a mix of thin and thick provisioned.
I understand that after I add the disk its best to do a reallocation -p on each flexvol, however a third party support has also mentioned that we should check to make sure that the target volume's space guarantee is enabled so that the reallocation scan does not cause an overcommitment of the volume's storage space.
Now my question is if you set the guarantee to 'volume' wouldnt this in essence make a Thin provisioned volume Thick provisioned? I am basing this on the following NetApp article

And is it necessary ? it seems a tad ambigious to me
Thanks in advance
