# zdb -S rpool/export/data
Dataset rpool/export/data [ZPL], ID 167, cr_txg 115855, 46.7G, 1793628 objects
So.. it seems that data is deduplicated, zpool has 54.1G of free space, but I
can use only 40M.
It's x86, ONNV revision 10924, debug build, bfu'ed from b125.
Please add me to the CC, because I am not on this alias.
Thanks.
