Truenas Core VM problem

[Hardwarejunkies]

Good morning everyone,

Im running Freenas / truenas core 12 for some while now. I just recent started to use VM for Nextcloud with ubuntu. (reason i stoped using jail for nextcloud is because of the certificate expire everytine). I use 2x kingstond 480GB sata SSD in pool. But the problem is i cant use full diskspace to assign for the VM. (only 300GB). Is this a new issue or am i doing something wrong?

My system,

Ryzen 7 1700
32gb 2400MHz DDR4
Msi b450m bazooka plus
2x 120gb sata SSD (OS)
2x 480GB (ubuntu VM)
3x 2tb seagate ironwolf (plex and storage files)
