6.15 Expanding /EXAVMIMAGES on the KVM host
Use this procedure to expand /EXAVMIMAGES
using available space
on the KVM host.
On Exadata database servers, local disk storage is governed by a volume manager, with
all of the available storage space allocated to a single volume
group. In turn, the volume group contains numerous logical volumes
that support various file systems. On KVM hosts, most of the space is allocated to
/EXAVMIMAGES
, which is used for guest storage.
Typically, a modest amount of free space is preserved in the volume group so that a file system can be easily extended if required. Additional space is also available by adding the disk expansion kit to a database server. The kit consists of 4 hard drives, which are installed in the unused slots in the database server.
Note:
The disk expansion kit is supported on 2-socket Oracle Exadata Database Machine systems only.If you installed the disk expansion kit, ensure that you have completed the procedure outlined in Adding the Disk Expansion Kit to Database Servers: X8M-2 and Prior before you proceed with this procedure:
