1, the difference between the twoDu,disk usage, is to calculate the size of each file by searching for files and then add up, du can see the files are just some currently exist, and it has not been deleted. The size of his calculations is the cumulative sum of all the file sizes that he currently thinks exist.Df,disk free, through the file system to quickly get information about the size of the space, when we delete a file, this file does notis immediately disappear in the file system, but tempo

DF displays a much larger percentage of the used disk occupancy than du statistics. The reason is mainly due to the different ways of calculating the results. First, the experimental situation1.

This morning received a Netizen's help, saying that the root partition of the server is full. However, there is no specific large file to find. Because the fault is really weird, I will come to the relevant account password of the failed server.

First, DF function: Displays the available disk space on the disk partition, with the default display in kilobytes. You can use this command to get information about how much space the hard disk is taking up and how much space is left. Options: -A: Includes all file systems -H: Displays the information unit display in a more readable manner g,m,kb -

App server root full, always alarmDF shows that the root partition has used 90% of the space, but the sum of the Du root partition is only about 40G, the partition should not have a large number of small files, so there should be no large number of small files caused by block write full problem.Online search issued by the existing may be a program to operate large files resulting in the file handle is not released, these programs are occupied by the file handle will be

Document directory Du command: DF command: Unallocated space in the file system is used to determine the size of allocated space in the file system. For example, if a file system contains 8192 512-byte blocks and 4096 are not allocated, the allocated space is 4096-byte blocks. Allocated space = total space-unallocated Space Because the calculation is based on the overall file system, the DF command is

Du, df, and Linuxdudf in Linux During Linux O M, it is often found that the values of du and df are different, and sometimes they are very different. In specific circumstances, df may see that the disk is full, but du determines that the disk space is large. The file system allocates some disk blocks to record some of its own data, such as I nodes, disk distr

Why is the use of Du and DF to view disk capacity inconsistencies, whether there are bugs or disk fragments, or which result should prevail. In fact, the values of the two commands are inconsistent due to differences in implementation of DU and DF commands, rather than failures.[Root@www ~]# Du-sh/home4.7g/home[Root@www ~]# df-h/homeFileSystem Size Used Avail use

In Windows, you can easily view disk space, but you may be confused about how to view disk space in Linux. Don't worry. in Linux, you can use the following command to query logs. UseDFCommand to view the disk attributes, including the file system type, disk size, used size, remaining size, usage percentage, and so on. UseDuCommand to view the folder and file size. The Command Parameter-H is used to make it easy for you to understand the size of each file. Without this parameter, the size of
