Reference Example

Add 100 MB of space to logical volumes:

[root@linuxcool ~]# lvextend -L +100M /dev/vg1000/lvol0Extending logical volume lvol0 to 300.00 MB Logical volume lvol0 successfully resized

Extend the size of logical volume 'vg0/lvol10' by 100M on physical volume/dev/sdk3:

[root@linuxcool ~]# lvextend -L +100 /dev/vg01/lvol10 /dev/sdk3

Extend logical volume "vg01/lvol01" to 160MB using physical extents/dev/sda:8-9 and/dev/sdb:8-9:

[root@linuxcool ~]# lvextend -L+160 vg01/lvol01 /dev/sda:8-9 /dev/sdb:8-9 Above is the detailed content of the method of expanding logical volume space using linux lvextend command. Have you learned anything after reading it? If you want to know more, welcome to the industry news!
