add home2

If you are mounting an existing volume with data, do not create partitions or filesystems. All data will be lost. Vultr does not back up Block Storage. Make sure you have a backup before making any changes to block storage volumes.

Create new empty partitions:
# parted -s /dev/vdb mklabel gpt
# parted -s /dev/vdb unit mib mkpart primary 0% 100%

Create new empty filesystem:
# mkfs.ext4 /dev/vdb1

Mount the volume after it has been prepared.

Mount block storage:

# mkdir /home2
# echo >> /etc/fstab
# echo /dev/vdb1               /home2       ext4    defaults,noatime,nofail 0 0 >> /etc/fstab
# mount /home2

#systemctl daemon-reload

lsblk is a utility for listing block devices. You can use it to view disks and partitions on your Linux computer as follows. It runs well without the sudo command:
