/dev/sde is our system drive/dev/sda is our new drive (I bought 2TB drive)
Let’s copy with dd all of data from /dev/sde to /dev/sda. Run it inside virtual terminal tmux:
If there are running virtual machines - stop it, otherwise we can get read only file system.

tmux
dd if=/dev/sde of=/dev/sda bs=64K conv=noerror,sync oflag=sync status=progress

We can check the filesystem:

|
sudo vi /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fsck.mode=force fsck.repair=yes"
sudo update-grub
sudo reboot
|
After reboot our new disk is /dev/sde
Resize the volume from 1Tb to 2Tb. Go to fdisk:
sudo fdisk /dev/sde
