Linux Operating System has lots of different file system alternatives, with all the existing default is commonly used ext4. File systems are generally utilized in order for handling how the information is kept soon after any program no longer is utilizing it, how accessibility to the information is managed, what other information (metadata) is linked to the data itself, etc. This article helps you to understand the difference between Linux XFS vs EXT4 File System.
Compare Linux XFS vs EXT4 File SystemLinux XFS vs EXT4
Ext4 File System:
Ext4 is short for fourth extended file system, it was introduced in 2008. It is really a reliable file system which has long been the default option for almost the majority of all distributions for the past couple of years, it is produced from an aging code base. Using several techniques ext4 improved in speed compair with ext3. It’s a journaling file system because of this it will maintain a journal of where the files are mainly located on the disk as well as any other changes that occur to the disk. If your system crashes, the chance of file system corruption is less due to journaling.
Maximum Individual file size can be from 16 GB to 16 TB
Maximum File System Size is 1EB(exabyte)
Maximum it contains 64,000 subdirectories (32,000 in ext3)
XFS File System:
XFS is a high-performance 64-bit journaling file system, which was designed by SGI for their IRIX platform. XFS features a variety of improvements that allow it to be stand out on the list of file system crowd, for example journaling for metadata operations, scalable/parallel I/O, suspend/resume I/O, online defragmentation, delayed allocation for performance, etc.
XFS was combined into Linux kernel in about 2002 and In 2009 RHEL Linux version 5.4 usage of the XFS file system. XFS has always been a preferred option for many enterprise systems particularly with massive amount of data, because of its high performance, architectural scalability and robustness. Now RHEL/CentOS 7 and Oracle Linux utilize XFS as their default file system.
Maximum Individual file size can be from 16 TB 16 Exabytes
Maximum File System Size is 8EB(exabyte)
Drawback: XFS file system cannot be shrunk and poor performance with deletions of the large numbers of files.
Common Commands for ext3/4 and XFS:
Task ext3/4 XFS
Create a file system mkfs.ext4 or mkfs.ext3 mkfs.xfs
File system check e2fsck xfs_repair
Resizing a file system resize2fs xfs_growfs
Save an image of a file system e2image xfs_metadump and xfs_mdrestore
Label or tune a file system tune2fs xfs_admin
Backup a file system dump and restore xfsdump and xfsrestore
Generic tools for ext2 and XFS:
Task ext4 XFS
Quota quota xfs_quota
File mapping filefrag xfs_bmap
