Hi,
I finally switched my two VMWare Server to Proxmox. The first server run without problems so today I installed my second server with proxmox.
I used a 2,6TB Raid 5 for my system and a ~8TB Raid 5 for my storage

Proxmox could see the 8TB storage but only using around 4TB of it. If i delete the Raid and create a new one, the same thing happend.

How can I use the whole 8TB storage?
 
Hi @Energy , welcome to the forun.

As shown in your screenshot, the 8TB has a 3.6TB partition, likely pre-existing from your prior use. You can examine the type of the partition by running blkid

If you determine that you no longer need this partition, you can remove it via various methods:
wipefs -a /dev/sdb
sgdisk --zap-all /dev/sdb

etc.
