This article is about how to turn off the Centos write disk feature. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

A Linux file has 3 times by default.

Atime: the access time to this file.

Ctime: when the inode of this file changed.

Mtime: the modification time of this file.

If you have multiple small files (such as multiple small images on the page of the Web server), it is usually not necessary to record the access time of the files, which can reduce the number of write disks. How to configure this?

First, modify the configuration file of the file system: vim / etc/fstab. Then, use the noatime and nodiratime commands in partitions that contain a large number of small files.

For example: / dev/sda5 / data/pics ext3 noatime,nodiratime 0 0 so that when the file is accessed, it will no longer produce Imando O to write to disk.
