ZFS ZFS can't destroy snapshot

newbeastie

Greetings, I'm using FreeBSD 13.5. I need to snapshot my /home/beastie directory but I made a bad mistake. I created datasets for directories. After that, I decided to create a snapshot for testing but I saw snapshot having "USED 0B". I mounted it and no file is seen. After all, I wanted to delete this snapshot but it gave an error saying "dataset is busy". I even tried "-f" argument but nothing changed. "mount" command doesn't show any mounted snapshot.

Here is my zfs-list:
Code: 
NAME                    USED    AVAIL    REFER    MOUNTPOINT
root                    3.69G    2.60G    3.69G    none
root/home                48K        2.60G    24K        /home
root/home/beastie        24K        2.60G    24K        /home/beastie
root/home/beastie@s0    0B        -        24K        -
 
Maybe you mounted your newly created home dataset onto your home containing some files? Like your root/home/beastie dataset is sitting on your actual home? Be careful to not delete your home files accidentally, since destroying the dataset may delete the folder too.

Thanks. I found the solution. It looks like I added a hold to snapshot. I need to release it before destroying the snapshot.
