VG. I want to extend /dev/system/root: # lvextend -l+2 /dev/system/root /dev/sdc1 Extending logical volume root to 5.01 GB Insufficient free space: 1282 extents needed, but
only 766 available Or # lvextend -l+2 /dev/system/root Extending logical volume root to 5.01 GB Insufficient free space: 1282 extents needed, but
only 943 available Same if I specify actual size (in MB or GB) instead if
number of PEs. Looks like it tries to reallocate the whole to the already existing LV. What I am not understanding or missing here? Respectfully, Nikolay V.
