After its snapshot was deleted, Z was nearly empty.
Make sense??
Okay, so as I suspected almost all of the data was removed from the Z file system. As long as you were having a snapshot available, the removed data was still on disk and reachable through it. Destroying the snapshot was the bad move. There is probably not that much you can do now (easily) to recover your data. Perhaps something could have been done should you have exported the pool immediately after the zfs destroy.

Btw, 'zpool history' does not show zfs command history.
meaning you aren't running a recent Solaris 10 update. I believe logging zfs logging was added four years ago.

NAME
sharefs - Kernel sharetab filesystem DESCRIPTION
The sharefs filesystem describes the state of all shares currently loaded by the kernel. It is mounted during boot time as a read-only file at /etc/dfs/sharetab. Filesystem contents are dynamic and reflect the current set of shares in the system. File contents are described in sharetab(4). File contents can be modified as a result of share(1M), sharectl(1M), sharemgr(1M) and changing properties of a zfs(1M) data set. The module may not be unloaded dynamically by the kernel. FILES
/etc/dfs/sharetab System record of shared file systems. SEE ALSO
