Default Disk Partition Layout

Oracle Linux, at installation, provides a default disk partition layout.

The default partitioning schema uses XFS as the default file system on each volume, except /boot/EFI, which uses VFAT.

Using LVM for /, /home, and /swap makes it easier to resize these allocations after installation if more disk space is made available.

The default partition schema is described in the following table:

Table 1-1 Default Partitioning

Volume Description File system type Size
/boot Boot partition XFS 1 GiB (fixed)
/boot/EFI EFI system partition (EFS) VFAT 600 MiB (fixed)
LVM Group
/swap Swap volume XFS

Swap size is calculated based on the amount of memory available:

  • If memory is less than 2 GiB, swap is twice the amount of memory available.
  • If memory is greater than or equal to 2 GiB, but less than 8 GiB, then swap is equal to the amount of memory available.
  • If memory is greater than or equal to 8 GiB, but less than 64 GiB, swap is equal to half the amount of memory available.
  • if memory is greater than or equal to 64 GiB, then swap is set to a fixed size of 4 GiB.
/ Root volume XFS 70 GiB or 50% of available disk space after /boot and /swap are configured - whichever is smaller. Minimum size is 1 GiB.
/home Home volume XFS Remainder of disk space. If the total available disk space is 50 GiB or less, a home partition isn't created. Minimum size is 1 GiB.
