Learning from linux-disk management and learning from linux 1: df is used to view the capacity information of mounted disks. -I. View inodes usage -H is displayed in proper units -K-m is displayed in k M units. 2: view the space occupied by a file or directory by du [-abckmsh] [file name and directory name] The du + directory only lists the sizes of directories and Their subdirectories.

Linux disk relationship knowledge and linux disk experience I have learned more or less about linux disk management, including hard disks, logical disks, and lvm, however, I encountered a lot of problems and confusions when I checked the linux database yesterday. I also reviewed the related knowledge. First, let's take

-sector of the hard disk are the primary boot sectors. fdisk will write 512 bytes of records here, that is, MBR records. MBR Partition Table: (MBR meaning: Master Boot Record, Master Boot Record) Maximum supported volumes: 2 TB (T; terabytes, 1 TB = 1024 GB) Limit on partitions: a maximum of four primary partitions or three primary partitions can be added with an extended partition (unlimited logical drives are supported in the extended partition) GPT

partition mode, up to 2TB only, up to the primary partition primary plus the extended partition extended is 4, want to multiple partitions need the fourth partition for the extended partition extended, and in the extended partition within a plurality of logical partitions. The extended partition is just a shell that does not support formatting and is really storing logical partitions. [[emailprotected] ~]# fdisk/dev/sdbwelcome to

physical memory shortages to some extent. If the current Linux host runs more services and needs more swap space to support the application, you can add a new swap partition for it. Using the mkswap Command tool, you can create a swap file system on the specified partition, and the target partition should first set the ID to 82 through the Fdisk tool. ： 650) this.width=650; "Style=" background-image:none;

and only mount the root directory, that directory will be able to have the root home directory, so we would like Root home directory and root directory to be placed in the same partition. /sbin Linux has a lot of instructions to set up the system environment, these instructions only root can be used to set up the system, the other users can only be used to query. Placed under the/sbin for the boot process required, which includes t

On a Linux server, when the partition planning of an existing hard disk does not meet the requirements (eg: too little space left on the root partition to continue installing a new System program), the partitions on the hard disk need to be redesigned and adjusted, and sometimes new hard disk devices need to be added to extend the storage space. To do this requires an FDISK disk and partition management to

file system is based on a storage device, such as a hard disk or a CD, and maintains the physical location of the file. It can also be said that the file system is also a method for storing virtual data or network data, such as NFS;En.wikipedia.org/wiki/Filesystem 2. Understand the keywords of the file system; 0) storage medium: Hard Disk, CD, floppy disk, Flash disk, tape, network storage device, etc; 1) disk segmentation: This is for large-capacity storage devices, mainly refers to hard disks

I. df commandDF comes from the coreutils software package and comes with it during system installation. We can use this command to view the disk usage and the location where the file system is mounted. For example: [Root @ localhost beinan] # DF-lHFilesystem capacity in use available % mount point/Dev/hda8 11g 6.0g 4.4g 58%//Dev/SHM 236 M 0 236 m 0%/dev/SHM/Dev/sda1 56G 22g 35g 39%/mnt/sda1We can see that the system is installed in/dev/hda8; there is also a 56 GB disk partition/dev/sda1 mounted

Here is another option: "Recover System Boot", which will be used in future systems, the system uses it for recovery when a problem occurs. click Next, as shown in figure 4.Configuring partitions is a key step. If you do not do this, you will lose the useful data on the hard disk. Please be careful. The main reason why som

I believe many new users who want to learn linux are wondering what linux learning courses are good.

In the process of using Linux, it is sometimes due to improper partition caused by the installation of the system due to the lack of partition space, and some areas of excess space. For example: I installed the system to the/usr/local distributor 5G space, but after using a process found that/usr/ Local only uses up to 1G. This can adjust the/usr/local size to 1G. Leave 4G for his use. This paper summarizes the method of adjusting file system size wit
