How the Inode works:A file includes metadata and data content, metadata is stored in the Inode table, and the data content is stored in block blocks, and the Inode holds metadata entries for each file, including some basic meta-data such as

A case of an application of the inode is that when the file is created, there is not enough space to see through DF to find that actually used is only 20%, and here is why Du and DF see the same disk when the size is inconsistent (you can try it

The Linux hard disk is organized as: Boot Zone, super block (superblock), index node (inode), data Block (DataBlock), directory block (Diredtory block). Where the Super block contains the overall information about the file system on that hard disk

Generally speaking, we say that the process has a file descriptor table, the file descriptor list pointer to an inode, which omitted the File,dentry object, on the exact understanding of the VFS structure is useless, this article in conjunction with

The inode node records important information such as the file type, size, permission, owner, number of file connections, Creation Time, and update time, another important thing is to point to the data block pointer. In general, no special

Inode Index NodeInode ( Index Node table contains a list of all file system filesA node (an index node) is a table item that contains information about the file (metadata), including:file type, permissions, UID , GIDNumber of links (pointing to the

Ubuntu Install H3C INode Client? Before looking for a lot of methods on the Internet, but also found a lot of installation packages, but because of a variety of problems, and finally did not succeed (because they are too much food). And the school

Image is downloaded and managed by layer, the new image downloaded files temporarily stored in the/var/lib/docker/tmp, the file name is getimageblobxxx (xxx is a bunch of random numbers), these temporary files are packaged as a layer of tar.gz and

Inode operations on files in linux, block changes 1. create a file system and mount it: inode. The block information is as follows: filesystem Inodes IUsed IFree IUse % Mounted on/dev/sdb5 28112 11 28101 1%/test5/dev/sdb6 28112 11 28101

Inode: In Unix systems, each file has an inode, which is identified by an inode number. Inode contains the user of the file and the owner of the group, the access mode (read, write, and execute permissions), and the file type.   Fat and NTFS are

IntroThere are many implementations of UNIX file systems, such as UFS (BSD-based UNIX file systems), Ext3, Ext4, ZFS, ReiserFS, and so on.Regardless of the file system, you always need to store the data. the minimum storage unit for a hard disk is a

Today, there is a Web site on the Linux server and login not up, there is a website has been prompted to verify the code error,Before the occurrence of similar problems, the reason is because the server inode node is full, the last time is the/tmp

Server is generally required for long-term continuous operation, automatic task generated by the various files and logs, may make space full, resulting in business failures, so to regularly clean up.In general, there are two types of Linux space:1,

Once the business upgrade, found that the business process on the production system UPRG can not start, the log error: Can not create UPRG.log, but the observation/logs directory remaining space there are many. Try to directly under the/logs touch

 In Linux, a process accesses a file through a file descriptor (a filename descriptors, or FD) rather than a file name, which is actually an integer. Linux specifies that each process can use a maximum of Nr_open file descriptors at the same time,

Today , a login server Web site found that login did not generate a session. Based on past experience, it is generally because the space is full that the session file generation failed.Df-hfilesystem Size used Avail use% mounted
