Starting with centos7.0, the default file system is xfs, centos6 is ext4, and centos5 is ext3
The biggest difference between ext3 and ext4 is that ext3 takes a lot of time to fsck (the more files, the longer it takes), while ext4 takes much less time to fsck
ext4 is the fourth generation of extended file system (English: Fourth EXtended filesystem, abbreviated as ext4) is a log file system under the Linux system, which is the successor to the ext3 file system
ext4's file system capacity reaches 1EB, while the file capacity reaches 16TB, which is a very large number. This may not matter to desktops and servers in general, but it is important for users of large disk arrays.
ext3 currently only supports 32,000 subdirectories, while ext4 removes this limitation and theoretically supports an unlimited number of subdirectories
xfs is a very good log file system designed by SGI. XFS is known as the industry's most advanced and upgradable file system technology
xfs is a 64-bit file system that supports a single file system of up to 8EB minus 1 byte, and the actual deployment depends on the maximum block limit of the host operating system. For a 32-bit Linux system, the size of the file and file system is limited to 16TB
XFS does do a better job than EXT4 in many aspects, EXT4 is limited by disk structure and compatibility issues, scalability and scalability are indeed inferior to XFS, and XFS has developed over many years, and the refinement of various locks is also better
