Cannot select devices when creating pool

[vinnie-ki]

When creating a new pool, the available devices (VMWare virtual hdd's), don't show up in zfsmanager. Only a VMWare-virtual cd-rom drive. The disk's have a GPT disklabel with no partitions on them.

When using the command line, I'am able to make a new pool with command:
sudo zpool create -f zfs_pool_1 mirror /dev/sdc /dev/sdd

After that, the new pool does shows up in zfsmanager.

After destroying the pool in zfsmanager, above problem repeat's itself again. Also the destroyed pool cannot be found when importing a pool by searching for destoyed pools.

Using Ubuntu LTS 16.04 as VM under Esxi 6.0 U2 | Webmin 1.870
