As we all know, the Inode code in the file system is the unique number that points to the disk block, if the server is compromised or the log file runs out of the disk Inode resource number, the new data cannot obtain the inode number resulting in no The method store. Example: viewing an existing Inode resource on disk in the/boot standalone partition and creating a large number of file consumption depleted inode numbers through a for loop, causing the disk to not write to the content and finally processing the failure.
