Oh. Fortunately this is an easy one to answer. Since zfs receive is an atomic operation (all or nothing) you can't overwrite a filesystem unless there is enough disk space for *both* the old version of the filesystem, and the new one. It essentially takes a snapshot of the present filesystem, then creates the new received version, and only after successfully receiving the new one does it delete the old one. That's why ... despite your failed receive ... You have not lost any information in your receiving filesystem. If you know you want to do this, and you clearly don't have enough disk space to hold both the old and new filesystems at the same time, you'll have to destroy the old filesystem in order to overwrite it. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
