GPT with proxmox tool
To initialize a disk with a new GPT, use the initialize subcommand:
proxmox-backup-manager disk initialize sdb
Delete Partitions with parted
Before deleting a partition, back up your data. All data is automatically deleted when a partition is deleted.
- run the d command in the fdisk command-line utility.
Verify Partition Deletion
Reload the partition table to verify that the partition has been deleted.
- run the p command.
The terminal prints out the partition structure of the disk selected in Step 2.
Save Changes and Quit
- run the w command to write and save changes made to the disk.
Formatting Disk Partition with ext4 File System
Format a disk partition with the ext4 file system using the following command:
sudo mkfs -t ext4 /dev/sdb1
Next, verify the file system change using the command:
lsblk -f
