Chapter 2. Storage Considerations During Installation
Many storage device and file system settings can only be configured at install time. Other settings, such as file system type, can only be modified up to a certain point without requiring a reformat. As such, it is prudent that you plan your storage configuration accordingly before installing Red Hat Enterprise Linux 6.
This chapter discusses several considerations when planning a storage configuration for your system. For actual installation instructions (including storage configuration during installation), refer to the Installation Guide provided by Red Hat.
2.1. Updates to Storage Configuration During Installation
Installation configuration for the following settings/devices has been updated for Red Hat Enterprise Linux 6:
Fibre-Channel over Ethernet (FCoE)
Anaconda can now configure FCoE storage devices during installation.
Storage Device Filtering Interface
Anaconda now has improved control over which storage devices are used during installation. You can now control which devices are available/visible to the installer, in addition to which devices are actually used for system storage. There are two paths through device filtering:
- Basic Path
For systems that only use locally attached disks and firmware RAID arrays as storage devices
- Advanced Path
For systems that use SAN (e.g. multipath, iSCSI, FCoE) devices
Auto-partitioning and /home
Auto-partitioning now creates a separate logical volume for the
/home file system when 50GB or more is available for allocation of LVM physical volumes. The root file system (
/) will be limited to a maximum of 50GB whe creating a separate
/home logical volume, but the
/home logical volume will grow to occupy all remaining space in the volume group.
