I got this VPS from my friend and want to expand root volume because it’s too small.
root@MyServer:~# df -h
Filesystem Size Used Avail Use% Mounted on
udev 3.9G 0 3.9G 0% /dev
tmpfs 801M 460K 801M 1% /run
/dev/mapper/ubuntu--vg-root 8.3G 2.9G 5.1G 37% /
tmpfs 4.0G 0 4.0G 0% /dev/shm
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 4.0G 0 4.0G 0% /sys/fs/cgroup
/dev/xvda1 472M 133M 316M 30% /boot
tmpfs 801M 0 801M 0% /run/user/0
fdisk -l
show me there’s another disk xvdb
root@MyServer:~# fdisk -l

Is there anyway to expand my root volume using that 70GB of xvdb? I’m so new to Ubuntu 🙁
