Thanks, and sorry that I hadn’t seen > that myself! Hi, It might be worth to remove old snapshots referring to files you are about to delete. Even if you remove a lot of files the space won't be really reclaimed until you delete any references in snapshots to these removed files, if that makes sense. You should also consider to add a periodic scrub of your pool, once a week for consumer disks or once a month for enterprise disks, or what have you. Regards, Oscarhelp
