Note

Oracle Exadata System Software release 11.2.3.2.1 or later

root (/) partition

  • Use the df command to identify the amount of free and used space in the root partition (/):

df -h /

  • Use the lvs command to display the current volume configuration:

lvs -o lv_name,lv_path,vg_name,lv_size

  • Use the df command to identify the file system type that is used in the root partition (/):

df -hT /

  • Verify there is available space in the volume group VGExaDb using the vgdisplay command:

vgdisplay -s

  • Resize both LVDbSys1 and LVDbSys2 logical volumes using the lvextend command:

lvextend -L +10G /dev/VGExaDb/LVDbSys1
lvextend -L +10G /dev/VGExaDb/LVDbSys2
or
lvextend -L 60G /dev/VGExaDb/LVDbSys1
lvextend -L 60G /dev/VGExaDb/LVDbSys2

  • Resize the file system within the logical volume:

For ext3 and ext4:
resize2fs /dev/VGExaDb/LVDbSys1
resize2fs /dev/VGExaDb/LVDbSys2

For the xfs:
xfs_growfs /
mkdir -p /tmp/mnt/root
mount -t xfs /dev/VGExaDb/LVDbSys2 /tmp/mnt/root
xfs_growfs /tmp/mnt/root
umount /tmp/mnt/root

  • Verify the space was extended using the df command

non-root (/u01) partition

  • Use the df command to identify the amount of free and used space in the /u01 partition:

df -h

  • Use the lvs command to display the current logical volume configuration used by the /u01 file system:

lvs -o lv_name,lv_path,vg_name,lv_size

  • Use the df command to identify the file system type that is used in the /u01 partition:

df -hT /u01

  • Verify there is available space in the volume group VGExaDb using the vgdisplay command:

vgdisplay -s

  • Resize the logical volume using the lvextend command:

lvextend -L +10G /dev/VGExaDb/LVDbOra1
or
lvextend -L 60G /dev/VGExaDb/LVDbOra1

  • Resize the file system within the logical volume:

For ext3 and ext4:
resize2fs /dev/VGExaDb/LVDbOra1

For the xfs:
xfs_growfs /u01

  • Verify the space was extended using the df command
