2.9 Extending LVM Partitions

Logical Volume Manager (LVM) provides flexibility to reorganize the partitions in the database servers.

Note:

• Keep at least 1 GB of free space in the VGExaDb volume group. This space is used for the LVM snapshot created by the dbnodeupdate.sh utility during software maintenance.

• If you make snapshot-based backups of the / (root) and /u01 directories by following the steps in Creating a Snapshot-Based Backup of Oracle Linux Database Server, then keep at least 6 GB of free space in the VGExaDb volume group.

This section contains the following topics:

• Extending the root LVM Partition
  The procedure for extending the root LVM partition depends on your Oracle Exadata System Software release.
• Resizing a Non-root LVM Partition
