Admin: /* resize LV */

== create LV ==
1. create disk partition (fdisk)
2. pvcreate /dev/sdb1
3. lvmdiskscan , pvdisplay , pvscan(to check)
4. vgcreate vg_newlvm /dev/sdb1
vgcreate vg_newlvm /dev/sdb1 /dev/sdc1
5. lvcreate --name centos7_newvol -l 100%FREE vg_newlvm
lvcreate -L 15G vg_newlvm
lvcreate -l 50%VG -n centos7_newvol vg_newlvm
6. lvdisplay (to check)
7. mkfs.ext4 /dev/vg_newlvm/centos7_newvol

==resize LV ==

1. Identify the Volume Group
vgs
2. Extend the Volume Group
vgextend myvolume /dev/sda2
3. Check
vgs , vgdisplay
4. Extend the Logical Volume
lvextend -l +100%FREE /dev/myvg/myvolume
Note: You can also extend the file system size using single lvextnd command by adding -r at end, example is shown below
lvextend -l +100%FREE /dev/myvg/myvolume -r
5. Extend the filesystem
xfs_growfs /dev/myvg/myvolume

==disable/delete LV ==
1. Delete the entry of the mount point from the /etc/fstab :
# cat /etc/fstab
...
/dev/mapper/datavg-testlv /data01 ext4 defaults 0 0
...
2. Unmount the mount point :
# umount /data01

3. Disable lvm :
# lvchange -an /dev/datavg/testlv

4. Delete lvm volume :
# lvremove /dev/datavg/testlv

5. Disable volume group :
# vgchange -an datavg

6. Delete volume group :
# vgremove datavg

7. Delete physical Volumes being used for the volume group “datavg” :
# pvremove /dev/sdb /dev/sdc
