Storage Volume Discrepancies
I've got a data storage volume that states usage is 14.4TiB of 15TiB. When reviewing the actual "drive" associated to the volume it shows 7.45TB free. What exactly am I missing on this? Thanks!

Re: Storage Volume Discrepancies
Hi @jimvad
It may be something to do with the zero-page reclamation (ZPR). You might want to run the unmap/trim on the filesystem in question to reflect the capacity on the storage array.
Further information can be found here.

Thank you
