Hua, The behavior below is described here:
http://docs.sun.com/app/docs/doc/819-5461/setup-1?a=view The top-level /tank file system cannot be removed so it is less flexible then using descendent datasets. If you want to create snapshot or clone and later promote the /tank clone, then it is best to create separate ZFS file systems rather than using /tank. Cindy On 10/10/09 17:00, Hua wrote:
I understand that usually zfs need to be created inside a zpool to store files/data. However, I quick test shows that I actually can put files directly inside a mounted zpool without creating any zfs. After zpool create -f tank c0d1 I actually can copy/delete any files into /tank. I can also create dir inside /tank. I haven't seen any documentation talking about such an usage. Just wonder whether it is allowed or is there any problem that I use zpool this way?
