I'd like to resize an existing LVM partition and add the space to another LVM partition.
[root@dckapstaging ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg_dckapstaging-lv_root 50G 50G 0 100% /
tmpfs 3.9G 0 3.9G 0% /dev/shm
/dev/sda1 485M 91M 369M 20% /boot
/dev/mapper/vg_dckapstaging-lv_home 215G 93G 111G 46% /home
I want /dev/mapper/vg_dckapstaging-lv_root
to be extended to another 15 GB from /dev/mapper/vg_dckapstaging-lv_home
; how can I do it?
