Where are the 250GB? You've started with 600GB missing. Now it's 250GB. Looks like we've just found 350GB. :-) What does "zfs list -r -tall -o space tank" show? df does not give you complete picture. > > It is also unclear, as is the free space. > # zpool list tank says 270GB zpool gives you raw numbers. That's what filesystem layer uses to store its= data > # df -h says 249GB free "zfs list" or df would give you amount of usable disk space that filesystem would make available to user. My guess is that this number would be more relevant in most cases than the number zpool gives you. --Artem > > > -- > Vladislav V.
