Resizing an ext3 LVM2 volume

Sasha Uncategorized
The process of resizing an LVM volume is pretty straightforward, but it’s important to take care in performing them — one false step and say goodbye to the data on that disk. 
  1. Shut the machine down
  2. Boot off a live CD or rescue disk
  3. Skip mounting your existing volumes
  4. Run lvm vgchange -a y
  5. Ensure that the volume group and logical volumes are visible
  6. Run e2fsck -f VOLUME to ensure the existing data on the volume is intact and the file system is sane
  7. Run resize2fs -p VOLUME SIZE[M|G] to resize the file system on the volume to the intended size
  8. Run lvm lvreduce -L VOLUME to resize the logical volume to the preferred size
  9. Run resize2fs VOLUME again to fill up the logical volume
