Linux system is now a very popular operating system, in Linux, everything is a file, because there are many operations can be completed by the file system, and the file system can meet the normal use of users, then what are the common file systems in Linux? Let me introduce you.

Generally speaking, in Linux, the system can support more file systems than Windows system, up to dozens of kinds, so Linux system is also an excellent operating system. Introduction to common file systems in Linux:

1. Ext3: it is a log file system, which can avoid the loss of file system data when the system is abnormal, and can repair data inconsistencies and errors. At the same time, when the hard disk capacity is large, the repair time will also increase, and there is no guarantee that 100% data will not be lost. Every write action detail of the whole disk will be recorded in advance. Avoid the interrupted part that can be traced when an exception occurs, and try to fix it.

2, Ext4: is the last improved version, is the default file management system in the RHEL 6 system, supporting storage capacity up to 1EB, but also an unlimited number of subdirectories, in addition, the file system can allocate block blocks in batches, thus greatly improving the efficiency of reading and writing.

3. XFS: it is a high-performance log file system, and it is the default file management system in RHEL 7. The advantage is that it can quickly recover files that may be destroyed in the event of an accident. Powerful logging functions only need to spend low computing and storage performance, and the maximum storage capacity is 18EB, which almost meets a variety of needs.
