Ubuntu – How to check whether I am using LVM

gpartedlvmpartitioning

I installed Ubuntu by choosing the option "Something else" at the step called "Allocate drive space" of the installer. Then I created my own partition table.

Now that Ubuntu is installed, can I check whether I am using LVM for my volumes ? In particular, can I see it in GParted Partition Editor ?

You should see it in Gparted. You can also just check your fstab file:

cat /etc/fstab

Watch the line with your root filesystem. Three possibilities here:

  1. If the line starts with UUID=xyz, this means it's a physical partition.
  2. If the line starst with /dev/sdaX, it also means it's a physical partition.
  3. The indicator for LVM would be something with /dev/mapper/xyz.
