Part I File Systems and Mounting

  • 1 Overview of File Systems in Linux
  • SUSE Linux Enterprise Server ships with different file systems from which to choose, including Btrfs, Ext4, Ext3, Ext2 and XFS. Each file system has its own advantages and disadvantages. For a side-by-side feature comparison of the major file systems in SUSE Linux Enterprise Server, see https://www.suse.com/releasenotes/x86_64/SUSE-SLES/15-SP2/#allArch-filesystems (File System Support and Sizes). This chapter contains an overview of how these file systems work and what advantages they offer.

  • 2 Resizing File Systems
  • Resizing file systems—not to be confused with resizing partitions or volumes—can be used to make space available on physical volumes or to use additional space available on a physical volume.

  • 3 Mounting storage devices
  • This section gives an overview which device identificators are used during mounting of devices, and provides details about mounting network storages.

  • 4 Multi-tier Caching for Block Device Operations
  • A multi-tier cache is a replicated/distributed cache that consists of at least two tiers: one is represented by slower but cheaper rotational block devices (hard disks), while the other is more expensive but performs faster data operations (for example SSD flash disks).
