How much space is used by my ZFS snapshots?
That’s the question I asked. I found the answer here.
$ zfs list -ro space NAME AVAIL USED USEDSNAP USEDDS USEDREFRESERV USEDCHILD system 9.35T 10.9T 0 329K 0 10.9T system/root 9.35T 1.18M 640K 567K 0 0 system/rootfs 9.35T 2.14G 90.9M 2.05G 0 0 system/tmp 9.35T 43.6M 14.5M 29.1M 0 0 system/usr 9.35T 10.9T 18.3K 329K 0 10.9T system/usr/home 9.35T 20.3G 0 329K 0 20.3G system/usr/home/dan 9.35T 20.3G 6.43G 13.9G 0 329K
Hope that helps.
