[zfs-discuss] Howto reclaim space under legacy mountpoint?

2010-09-19 Thread Gary Gendel
I moved my home directories to a new disk and then mounted the disk using a 
legacy mount point over /export/home.  Here is the output of the zfs list:

NAME USED  AVAIL  REFER  MOUNTPOINT
rpool   55.8G  11.1G83K  /rpool
rpool/ROOT  21.1G  11.1G19K  legacy
rpool/ROOT/snv-134  21.1G  11.1G  14.3G  /
rpool/dump  1.97G  11.1G  1.97G  -
rpool/export30.8G  11.1G23K  /export
rpool/export/home   30.8G  11.1G  29.3G  legacy
rpool/swap  1.97G  12.9G   144M  -
users   32.8G   881G  31.1G  /export/home

The question is how to remove the files from the orginal rpool/export/home (non 
mount point) rpool?  I a bit nervous to do a:

zfs destroy rpool/export/home

Is the the correct and safe methodology?

Thanks,
Gary

 (non mount point) rpool?  I a bit nervous to do a:


set mountpoint to somewhere and decide for yourself.
