Extending a logical volume at LVM

[RIFAT]

Suppose that we have a volume group named VG-TEST and It contains a logical volume named LV-TEST. After adding new physical disk /dev/sdx , we want to give additional 100G space to the LV-TEST logical volume. Following procedure is applied to the server.

In our linux server we have to create a new partition on the disk /dev/sdx. To do that:

# fdisk /dev/sdx

fdisk utility asks for parameters so that we create a new partition sdx1

To create physical volume

# pvcreate /dev/sdx1



To add physical volume to the volume group VG-TEST

# vgextend VG-TEST /dev/sdx1



To extend the logical volume LV-TEST

# lvextend -L+100G /dev/VG-TEST/LV-TEST

+100G means that we add extra 100G to the logical volume



We extended the logical volume. Now we should give this space server?s ext3 file system to use it.

# ext2online /dev/VG-TEST/LV-TEST
