*After these I just followed these steps.*

[root at SMDEV1-no-kid ~]# smbcontrol smbd close-share ctest
[root at SMDEV1-no-kid ~]# vim /etc/samba/smb.conf  (delete include line)
[root at SMDEV1-no-kid ~]# rm /etc/samba/shares/clspool.ctest.cifs (this was
the included line)
removed '/etc/samba/shares/clspool.ctest.cifs'
[root at SMDEV1-no-kid ~]# systemctl reload smbd
[root at SMDEV1-no-kid ~]# zfs destroy clspool/ctest
umount: /clspool/ctest: target is busy.
cannot unmount '/clspool/ctest': umount failed
[root at SMDEV1-no-kid ~]# lsof /clspool/ctest/
