# reboot Broadcast message from root (pts/0) (Thu Sep 2 15:08:07 2010): The system is going down for reboot NOW! 13.3 Extending an existing logical volume This section describes the process of adding a new minidisk to an existing LVM. This is useful when your logical volume has run out of space. First, repeat the steps as described in 13.1, “Adding DASD” on page 191 to add a new minidisk. In this example, a minidisk at virtual address 104 is added of size 3338 cylinders. Don’t forget to logoff and log back on to LINUX02 so the new directory entry is read. When your system comes back, enable the new 104 disk, dasdfmt it and create a signle partition: # chccwdev -e 104 Setting device 0.0.0104 online Done # lsdasd Bus-ID Status Name Device Type BlkSz Size Blocks ============================================================================== 0.0.0100 active dasda 94:0 ECKD 4096 2347MB 600840 0.0.0101 active dasdb 94:4 ECKD 4096 2347MB 600840 0.0.0300 active dasdc 94:8 FBA 512 256MB 524288 0.0.0301 active dasdd 94:12 FBA 512 512MB 1048576 0.0.0102 active dasde 94:16 ECKD 4096 1173MB 300420 0.0.0103 active dasdf 94:20 ECKD 4096 1173MB 300420 0.0.0104 active dasdg 94:24 ECKD 4096 2347MB 600840 # dasdfmt -b 4096 -y -f /dev/dasdg Finished formatting the device. Rereading the partition table... ok # fdasd -a /dev/dasdg reading volume label ..: VOL1 reading vtoc ..........: ok auto-creating one partition for the whole disk... writing volume label... writing VTOC... rereading partition table... Creating a physical volume Use the pvcreate command to create a physical volume from the minidisk: # pvcreate /dev/dasdg1 Physical volume "/dev/dasdg1" successfully created Extending the volume group Use the vgextend command to extend the volume group into the new physical volume. Then, use vgdisplay to verify that the volume group has free space. # vgdisplay homevg --- Volume group --- VG Name homevg System ID Format lvm2 198 The Virtualization Cookbook for RHEL 6

Extend the logical volume and the file system Now that you have free space in the volume group, you can increase the size of the existing logical volume with the lvextend command. The -l option specifies the number extents to add. Finally, use the ext2online command to increase the size of the file system while it is still mounted. You can use the df command to show the file system size before and after you extend it as the following example shows: # df -h /home /dev/mapper/homevg-homelv 2.3G 68M 2.1G 4% /home # lvextend -l +586 /dev/homevg/homelv Extending logical volume homelv to 4.58 GB Logical volume homelv successfully resized # resize2fs /dev/homevg/homelv resize2fs 1.41.12 (17-May-2010) Filesystem at /dev/homevg/homelv is mounted on /home; on-line resizing required Chapter 13.
