Zfs and Solaris 10: a "nice" redundand clone and snapshot situation

I have this situation now zfs list -t snapshot|grep prova provapool/fs2@oggi 1K - 31K - provapool/fs3@domani 19K - 32K - provapool/fs5@domani 1K - 32.5K - I want to remove "fs2@oggi" zfs destroy provapool/fs2@oggi cannot destroy 'provapool/fs2@oggi': snapshot has dependent clones use '-R' to destroy the following datasets: provapool/fs1 provapool/fs4 provapool/fs5@domani provapool/fs5 provapool/fs3@domani provapool/fs3 I want to preserve fs3 fs4 fs5 so I promote it to independent fs zfs promote provapool/fs1 zfs promote provapool/fs4 zfs promote provapool/fs5 I want to remove "fs2@oggi" and... zfs destroy provapool/fs2@oggi cannot destroy 'provapool/fs2@oggi': snapshot has dependent clones use '-R' to destroy the following datasets: provapool/fs1 provapool/fs4 provapool/fs5@domani provapool/fs5 provapool/fs3@domani provapool/fs3 How to exit with this strange situation? I know a fast way: backup all, destroy with -R option and re-create the three fs, anyone know a more good solution?
