Chapter 11. Creating and Managing Filesystems
Linux supports a lot of filesystems, more than any other operating system. Filesystems are essential to computing and do an astounding amount of work. A computer filesystem stores, organizes, and protects our data, and is under continual stress from being constantly in use. As Linux users we are fortunate to have many first-rate filesystems to choose from.
In this chapter you will learn about the command-line tools for creating and managing the following general-purpose filesystems, which are fully supported on Linux and well maintained:
-
Ext4, the Extended Filesystem
-
XFS, the X File System; the X stands only for X
-
Btrfs, the b-tree filesystem, pronounced Butter FS
-
FAT16/32, File Allocation Table 16- and 32-bit
-
exFAT, Extended FAT, Microsoft’s newest 64-bit filesytem
Not included in this chapter are Microsoft’s NTFS or Apple’s HFS/HFS+/APFS. Linux has good support for Microsoft’s NTFS, both read and write. To try it, look for ntfs-3g (NTFS third generation) packages.
Support for Apple’s HFS/HFS+/APFS is unreliable. To give it a test drive, look for packages with hfs or apfs in the names, and make sure the description specifies they are for Apple filesystems.
There are many special-purpose filesystems, such as UBIFS and JFFS2 for CompactFlash devices; the compressed filesystem SquashFS, HDFS, CephFS, and GlusterFS for distributed computing; NFS for network file sharing; and many more. These could easily fill a large book ...
