How to resize the storage pools? I do not want to reformat my disk, but I do not have enough experience with this. I am on Ubuntu 18.04. What should I do step by step?

  • Please add the output of lvdisplay – Panki Nov 4 '19 at 15:57
  • I just added,take a look pls. – Richard Rublev Nov 4 '19 at 15:59
  • You've allocated all of the physical extents in your volume group to the three logical volumes. Where are you going to get the free/unused physical extents to resize the logical volume(s)? – Emmanuel Rosa Nov 10 '19 at 13:39
  • @EmmanuelRosa What should I do? – Richard Rublev Nov 10 '19 at 18:04
  • Start by adding the output of df -h to your question. – Emmanuel Rosa Nov 10 '19 at 22:48

Here's an example of reducing the size of the workspace logical volume by 10G, and then increasing the size of the db logical volume.

lvresize -r -L -10G /dev/mapper/volgroup-workspace
lvresize -r -L +10G /dev/mapper/volgroup-db
