Hello friends, when I create a backup disk it is only 83GB, the volume has 600GB and I wanted to use it completely.

This disk is in raid 0 , with DELL controller perc_H710 , this controller does not support non-raid.

Can someone help me ?


Seems like this is a different disk? Can you post your storage configuration (please wrap in CODE-Tags)?

cat /etc/pve/storage.cfg

Seems like you do not have the /dev/sdc mounted anywhere, so the directory storage is actually on your root disk. You need to format the disk and then create a filesystem on it. Then you can mount it where you want.

Select 'vmgpon' > 'Disks' > select /dev/sdc > 'Initialize Disk with GPT'
Then select 'Directory' submenu and create a filesystem of your choice on it via 'Create: Directory'
If you select 'Add storage', then the disk will be automatically added as storage

Very weird, did you use this disk otherwise before? If you are really sure that there is nothing left on the disk, and it is not otherwise used by your RAID controller you could try running the below command (which will destroy everything on the disk, so make sure to double-check)

sgdisk --zap-all /dev/sdc

Afterwards you can try again

Hi shanreich, I managed to solve the problem, thanks for the support.
As I sent in the print there was no partition created. I created a partition with 'fdisk' for test type 'extend' and then I deleted it, after that 3 hidden partitions appeared, I deleted the 3 , then I rebooted the server. All ok now.
