Linux2.6.19 kernel released in 2008. When the 2.6.28 kernel was released, EXT4 ended the development and began accepting users ' use. It seems that ext will become synonymous with Linux file systems. However, when you read many articles about EXT4, you will find that you have mentioned btrfs in unison, and that EXT4 will be a transitional file system. Ext4 's author Theodore Tso also praised Btrfs and beli

Btrfs is a very powerful file system on the Linux system, full name: B-tree, was developed by Oracle in 2007 based on the GPL agreement. So how do we create and use it for Btrfs file system?

Added some features not currently supported by EXT3/4, such as writable disk

Shared file system environment: In the parallel Sysplex environment, z/OS UNIX supports all LPARs users to access the entire file system, which is called a shared file system environment.
Owner system (owning system): The Sysplex member of the Mount file system is called the owning system, and the other member is called clients (not owning system).

Zfs and data deduplication
What is deduplication?
Deduplication is the process of eliminating duplicate data. The deduplication process can be based on the file-level file level, block-level block level, or byte-level bytes. Use highly probable hashAlgorithmTo uniquely identify data bl
