Disks, partitions and mounting (fstab)

Mount a disk and find it again at every boot.

1. List disks and file systems:

   lsblk -f
   sudo blkid

   Copy
2. Temporarily mount a partition:

   sudo mkdir -p /mnt/data
   sudo mount /dev/sdb1 /mnt/data

   Copy
3. For a permanent mount, add a line to /etc/fstab (use the UUID):

   UUID=xxxx-xxxx  /mnt/data  ext4  defaults,nofail  0  2

   Copy
4. Test before rebooting:

   sudo mount -a

   Copy
5. Monitor space:

   df -h
   du -sh * | sort -h

   Copy
