Hello,   Volume reserve is what you've allocated for volumes.   So you have to either shrink them, or delete some entirely.  (Note: If you shrink a volume, you must first shrink the filesystem)    Depending on how much you've actually written to the volume, you can thin provision volumes HOWEVER, doing so makes it possible to over provision the pool.  If you use up all the space, volumes will go offline, until you add more storage or delete volumes.  Additionally for optimal performance you need to leave at least 5% free space.    Regards,  Don 
I have a total of 30.34TB of storage.  Of that, 25.36TB is the Volume reserve.  I'm not talking the Snapshot reserve.  Is it possible to reduce this Volume reserve to open up storage space to create volumes or is the volume reserve tied to the current Volumes in use? If it is possible to reduce the Volume reserve, where to do I click....?  I am on V7.1.8 (R414953) firmware  Thanks
