Filesystem Management On Linux

filesystems to read and write data to and from hard drives. Besides having over a dozen filesystems of its own, Linux can read and write to and from filesystems used by other operating systems, such as Microsoft Windows. The kernel must be compiled with support for all types of filesystems that the system will use. The Table lists below is the standard filesystems that a Linux system can use to read and write data.

Filesystem Management Of Linux

Filesystem	Description
ext	: Linux Extended filesystem — the original Linux filesystem
ext2	: Second extended filesystem, provided advanced features over ext
ext3	: Third extended filesystem, supports journaling
ext4	: Fourth extended filesystem, supports advanced journaling
hpfs	: OS/2 high-performance filesystem
jfs	: IBM’s journaling filesystem
iso9660	: ISO 9660 filesystem (CD-ROMs)
minix	: MINIX filesystem
msdos	: Microsoft FAT16
ncp	: Netware filesystem
nfs	: Network File System
ntfs	: Support for Microsoft NT filesystem
proc	: Access to system information
ReiserFS	: Advanced Linux filesystem for better performance and disk recovery
smb	: Samba SMB filesystem for network access
sysv	: Older Unix filesystem
ufs	: BSD filesystem
umsdos	: Unix-like filesystem that resides on top of msdos
vfat	: Windows 95 filesystem (FAT32)
XFS	: High-performance 64-bit journaling filesystem

Any hard drive that a Linux server accesses must be formatted using one of the filesystem types listed.

The Linux kernel interfaces with each filesystem using the Virtual File System (VFS).

This provides a standard interface for the kernel to communicate with any type of filesystem. VFS caches information in memory as each filesystem is mounted and used.
