Zpool Export hang on newest release/ pre-release

[Mikeonut]

zfs-windows-2.3.0rc6f

Describe the problem you're observing

Having issues exporting a zpool volume. Gets stuck "running" even after cold boot.

Describe how to reproduce the problem

Issue persists on older versions also. Just mount the drive successfully and then try and export.

An example is provided below.

Example:
C:\Windows\System32>zpool export -a
zunmount(nodetitan/volatile,H:/volatile/) running
zunmount(nodetitan/volatile,H:/volatile/) returns 0
zunmount(nodetitan,H:/) running

Freezes here.

Have seen the same after copying a large file between ZFS filesystems

Copy of a 9 GB iso file between unencrypted filesystems hangs at 20%
Tried then a zpool export that does not work

 zpool export test
zunmount(test/data/2,ÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝì¦
¹Ýdata/2) running
zunmount(test/data/2,ÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝÝì¦
¹Ýdata/2) returns 0
zunmount(test/data/1,D:/data/1/) running
zunmount(test/data/1,D:/data/1/) returns -1
cannot unmount 'D:/data/1/': unmount failed

zunmount(test/data/1,D:/data/1/) returns 0
zunmount(test/data,D:/data/) running
zunmount(test/data,D:/data/) returns 0
zunmount(test,D:/) running
zunmount(test,D:/) retur

I have been having export issues when even just instantly exporting with no explicit file copy request, however the raid drive is used for filehistory, so that could be a factor, maybe it just copies big files instantly.

The subfolder "Volitile" Can copy large files directly to it anyway without any issue, its mainly the underlying raid drive.
