In the situation where you have exhausted all of the disk space in a volume group, you can add additional disks to the volume group in order to remediate the situation.<\/p>\n
Locate the additional disk using the fdisk -l command.<\/p>\n
[root@slave ~]# fdisk -l
\nDisk \/dev\/sdd: 3221 MB, 3221225472 bytes, 6291456 sectors
\nUnits = sectors of 1 * 512 = 512 bytes
\nSector size (logical\/physical): 512 bytes \/ 512 bytes
\nI\/O size (minimum\/optimal): 512 bytes \/ 512 bytes
\nThe next step is to create a LVM partition using the above disk (\/dev\/sdd).<\/p>\n
[root@slave ~]# fdisk \/dev\/sdd
\nType in n and press enter three times.
\nType in +2G and press enter.
\nType in t and press enter.
\nType in 8e and press enter.
\nType in w and press enter.
\nType in q and press enter.
\nRun partprobe to make the kernel aware of the disk changes.<\/p>\n
[root@slave ~]# partprobe
\nCheck the partition path by running fdisk -l.<\/p>\n
[root@slave ~]# fdisk -l
\nDisk \/dev\/sdd: 3221 MB, 3221225472 bytes, 6291456 sectors

\nCreate the physical volume using pvcreate.<\/p>\n
[root@slave ~]# pvcreate \/dev\/sdd1
\n Physical volume “\/dev\/sdd1” successfully created
\nWe\u2019re now going to add 2GB of space from the new \/dev\/sdd1 partition to the lvtestvolume volume group.<\/p>\n
[root@slave ~]# vgextend lvtestvolume \/dev\/sdd1
\n Volume group “lvtestvolume” successfully extended
\nVerify the size of the volume group by running vgdisplay lvtestvolume.<\/p>\n
[root@slave ~]# vgdisplay lvtestvolume

\nThe disk space has now been made available to the volume group, however the logical volume needs to be extended in order to make use of the additional space.<\/p>\n

\nWe can now use lvextend to add an additional 2GB of space to the lvtestvolume.<\/p>\n
[root@slave ~]# lvextend -L +2G \/dev\/lvtestvolume\/data
\n Extending logical volume data to 4.00 GiB

\nWe can finally verify the disk space addition from using lvdisplay \/dev\/lvtestvolume\/data or through using df -hk | grep \/data.<\/p>\n
