Presenting clones of Windows clients using ZVOL over iSCSI?

Question

ZFS

Good afternoon. Organized server operation on FreeBSD 11.2 (Xeon 2620, 128Gb ECC REG, Intel DC4502 3.84Gb, 10Gb Nic). The server distributes clones of the Windows system using zvol via ISCSI (CTL target), a simple script destroys the old clone and creates a new clone from the original before each client boot. In general, everything works fine, but there is one incomprehensible BUT!
If you "hook" the original disk with the Windows initiator and check for errors, there will be no errors. If you do the same with a clone, there will be no errors either. But if this is done already on a running client, it will write that there are errors, and the disk must be restored at the next boot. But the main thing is that such damage to the system still pops up, some programs sometimes refuse to start until you restart the computer, and the current clone is deleted and a new clone takes its place.
zpool config:
dedup=off atime=off sync=disabled compression=lz4, the rest is default.
Question! Where to dig, otherwise I'm already exhausted from finding an answer to be honest ...
