Thanks Richard for the prompt response. But second time same commands creates dir3 too.
I mean to say, as I said earlier, first time it gives the mounting error and does not create dir3 *# zfs create -p tank/dir1/dir2/dir3* *cannot mount '/tank/dir1/dir2': directory is not empty* *#* but if I issue the same command again(just after the above error ), it creates the dir3. After that "zfs list" shows dir3 but "df -h" still does not show dir2 as mounted. *# zfs create -p tank/dir1/dir2/dir3* ***# zfs list|grep tank* ***tank 290K 228G 33K /tank* ***tank/dir1 95K 228G 32K /tank/dir1* ***tank/dir1/dir2 63K 228G 32K /tank/dir1/dir2* ***tank/dir1/dir2/dir3 31K 228G 31K /tank/dir1/dir2/dir3* ***#* * # df -h|grep tank* * tank 229G 33K 229G 1% /tank* * tank/dir1 229G 34K 229G 1% /tank/dir1* * tank/dir1/dir2/dir3 229G 31K 229G 1% /tank/dir1/dir2/dir3* * #* On Mon, Jan 24, 2011 at 7:02 PM, Richard Elling <richard.ell...@gmail.com>wrote: > comment below... > > On Jan 24, 2011, at 1:58 PM, Rahul Deb wrote: > > I have a pool "tank" and "dir1" is the filesystem on that pool.
