The software packages for most of the Linux POSIX file systems (such as Ext2, Ext3, ReiserFS, and XFS) are installed and upgraded by default whenever you install or upgrade the SUSE Linux Enterprise Server (SLES) 11 SP 1 (or later) operating system on your OES 11 (or later) server. No action is required.
The Btrfs file system is available on SLES 11 SP2 or later. Using the Btrfs file system requires the btrfsprogs package. The package is installed automatically if you select Btrfs as the file system for the system device when you install the SLES 11 SP2 (or later) operating system. Otherwise, the btrfsprogs package must be installed manually by using the YaST 2 Software Installer. Thereafter, the package is updated by default whenever you patch or upgrade your system.
Updates for the Linux POSIX file systems and the btrfsprogs package are delivered via the SLES 11 SP2 (or later) patch channel.
