Where is my Free Space?

[zdv]

Hello,
I have 2 HDD in a mirror. filesystem is ZFS.
The system show me that HDD is used 99%. And there is a free space about 11 GB
I have deleted many data from HDD about 40 GB, BUT I have not gotten any additional free space. I still have only 11 GB !!!

What is happeninng? What should I do to get my free space?

your free space is in the snapshots. Delete the snapshots and your free space comes back.
