Foolishly I let my ZFS system run out of disk space. I've removed the = errant logs, but the space has not been returned. Not sure why. There = are no snapshots, and I've even desperately rebooted the machine, but = the space is still lost. # zfs list void/store NAME USED AVAIL REFER MOUNTPOINT void/store 57.2G 2.3G 57.2G /store # du -hs /store 34G /store Any idea on were the 23G has gone, or how I pursuade the zpool to return = it? Why is the filesystem referencing storage that isn't being used? To confirm, there are no snapshots here, so there shouldn't be anything = referencing that data. When I found the machine it had 0 available, but = I've found the 2.3G by removing some other files. Not sure why some = should hand the space back whilst others done. This is a bit of an emergency for me, so I'd really appreciate a quick = response if anyone knows! Many thanks, Joe p.s. this is FreeBSD 8.2 with ZFS pool version 15.=
