In-Depth Information
The partitioning screen has a great many options, and a complete description of all possible configuration
combinations cannot be provided in this chapter. It is best to align the storage configuration with your current
standards. That way you can't really make a mistake. For all the other detail please refer to the online manual. To keep
things simple and to prevent mistakes from happening it is often recommended not to present storage to the server,
which is not immediately required to install the base operating system at this stage. The commands necessary to
create storage mount points for the Oracle accounts will be described in a later section in this chapter.
The partitioning screen resembles the layout used in Oracle Linux 5, but the graphical representation in the
top of how full an individual disk is will only appear after clicking on it. The user interface has been uncluttered in
comparison with the previous version, but the functionality has remained the same. The “Create” button offers you to
create the following entities, disk space permitting:
•
Create a standard partition
•
Create a (software) RAID partition
•
Create a (software) RAID device
•
Create a LVM physical volume
•
Create a LVM volume group
•
Create a LVM logical volume
The “Edit” button allows you to make changes to the highlighted partition, the “Delete” button unsurprisingly
removes the selected entity. If you got stuck during the partitioning of your system and want to get back to square one,
click on the “Reset” button to undo your changes to the original layout.
Oracle Linux has a wider set of options of file systems available to format your disks. Apart from ext3, which was
the standard in Oracle Linux 5.x ext2, ext4, xfs, and Btrfs are available.

Caution
BTrFs is still considered experimental in the upstream kernel. You should probably not use it for production
systems yet.
A possible partitioning scheme in Oracle Linux includes the partitions listed in Table
5-1

File System recommendation
/boot
At least 200MiB, up to 2 GiB
Use either an ext2, ext3, or ext4 file system to be on the safe side.
The bootloader used in Oracle Linux 6, grub-0.97 has a number
of known limitations.
The boot partition, for example, cannot be in a LVM logical
volume, but it can be a software RAID device (with limitations).
Most hardware RAID controllers should be supported by Oracle
Linux 6, but check with your documentation whether you can
create
/boot
on a hardware RAID.
The virtual bootloader in Xen-based virtualization might have
problems with ext4, ext2 is tested and confirmed to work.
