I do not know if = you need to do a scrub or not to recover the free space or not.

It hasn't recovered the space, = but it at least is billing it to the right file system now: infinity# zfs list void/j/legacy-alpha=20 NAME USED AVAIL REFER MOUNTPOINT void/j/legacy-alpha 58.9G 4.11G 56.9G /j/legacy-alpha # du -hs /j/legacy-alpha 34G /j/legacy-alpha Hmm.
