Hat recommends that all critical data be backed up and verified before making any changes to the underlying storage as an unforeseen problem might occur.
1. Create a physical volume from a free disk or partition (e.g./dev/sdc1As a partition)
#pvcreate/dev/sdc1
2. Extend the volume group (/dev/sdc1Is an existing physical volume path ).
#vgextendvgdata/dev/sdc1
3. Extend the logical volume (/dev/vgdata/lvdataIs the existing logical volume path), which
