Linux Practicum: Removing an LVM Configuration on CentOS 7

[scottalanmiller]

Following our practicum example to create an LVM volume with XFS on CentOS 7, we will now see how to remove it.

First we need to edit /etc/fstab to remove the entry that we put there. This is generally easiest if done manually.

Then...

# umount /var/log2
# lvremove vg_logs/lv_logs
Do you really want to remove active logical volume lv_logs? [y/n]: y
  Logical volume "lv_logs" successfully removed
# vgremove vg_logs
  Volume group "vg_logs" successfully removed
# pvremove /dev/vdb
  Labels on physical volume "/dev/vdb" successfully wiped
# pvs
  PV         VG                    Fmt  Attr PSize  PFree 
  /dev/vda2  centos_lab-lnx-centos lvm2 a--  14.41g 40.00m

Quick and easy.
