How to resize partition/ recognize larger partition

[ReDnAx1991]

Hi all,

I run CasaOS on a VM with Debian 12 within Proxmox. I have enabled two drives scsi0 (32GB) and scsi1 (1,8TB).
I ran out of storage capacity and increased the scsi1 from 1,8TB to 2,7TB.

With parted I increased the partition size of /dev/sdb1 to the full 2,7TB, however when I have a look in CasaOS it sees that the drive has been increased to 2,7TB but still shows the 1,8TB as storage capacity.

I tried removing and mounting the storage using the CasaOS GUI without success. Does anyone know how to fix this?

Extra info:

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 32G 0 disk
├─sda1 8:1 0 31G 0 part /
├─sda2 8:2 0 1K 0 part
└─sda5 8:5 0 975M 0 part [SWAP]
sdb 8:16 0 2.7T 0 disk
└─sdb1 8:17 0 2.7T 0 part /mnt/Data_sdb1

Kind regards,

Found the answer via Chat.GPT. I had to sudo resize2fs /dev/sdb1
After everything I did with parted.

In parted I did the following:

• sudo parted /dev/sdb1
• print
• Fix (as parted noticed that there was unused space)
• quit

Restart system
Login
sudo resize2fs /dev/sdb1
