## e.g. remove swap LVM Volume /dev/rhel/swap
## vg=rhel, lv=swap
swapoff /dev/rhel/swap
lvremove /dev/rhel/swap
## comment out mounting of /dev/rhel/swap in /etc/fstab
## when you boot, you may enter emergency boot
## with dracut# prompt and get error message /dev/rhel/swap missing
## Fix by editing /boot/grub2/grub.cfg and
## remove the entry from the kernel boot option rd.lvm.lv=rhel/swap
vi /etc/default/grub
