disk-to-directory capacityNow we know that the overall data of the disk is in the Superblock block, but the capacity of each individual file is recorded in the Inode. How do you call these data under the text interface? Let's talk about these two
DF: Lists the overall disk usage of the file system;Du: Evaluating the disk usage of the file system (commonly used to estimate the capacity of the catalog)DF parameter:-A: List all file systems, including system-specific/proc and other file systems-
Disk Arrays, short for RAID (redundantparrayspofpinexpensivepdisks), refer to "cheap and redundant disk arrays. The principle is to use arrays as disk groups and use them in combination with the Design of Distributed Data arrangement to improve data
