Linux hard disk Partition: partition, format, mount, cancel mount, delete partition

1. Create a partition

Check to see if an unpartitioned hard disk exists

# fdisk-l

650) this.width=650; "Src=" http://note.youdao.com/yws/public/resource/7cab2b25f7845268da528679eea1885b/xmlnote/ 8bc7622684204302a80b7c7d820d4ee0/1418 "style=" Border:none;margin:auto;height:auto; "alt=" 1418 "/>

, the original hard disk is formatted and mounted, and the new hard disk is not partitioned

So, start partitioning

# FDISK/DEV/SDB

Enter m to view individual command options

Enter P to view the current hard disk partition status

Enter N to create a new partition

e Create the extended partition, p to create the primary partition. Here, first create a primary partition, first create partition number 1th, the starting point is the default

, direct enter, set the end point, the partition of how much to write how big, I wrote is 2G

If you separate a primary partition, create an extended partition and a logical partition

The partitioned 2-bit extended partition in the figure, with the logical partition starting with ordinal 5.

Enter command W to save the partition

2. Format the partition

Two commands implement MKFS.EXT4 or MKE2FS (default format to EXT4 format).

3. Mounting

# MKDIR/MNT/SDB1 //Build Mount Directory

# MKDIR/MNT/SDB5

# MOUNT/DEV/SDB1/MNT/SDB1 //mount, same as SDB5 method

Mounted successfully.

4. un-mount

# UMOUNT/MNT/SDB1

5. Cancel Partition

# FDISK/DEV/SDB

First enter P to view, then use command D to delete, last w save.

Additional:

The above mount operation fails after the server restarts, and if you want the server to mount automatically when it starts, you need to edit the Fstab file

The last line adds the last line to automatically mount the boot. There are altogether 6 columns of documents, respectively, representing:

First column: Device name or device volume label name, (/DEV/SDA10 or label=/)

Second column: Device mount directory (e.g. "/" or "/mnt/d/" above)

Column three: Device file system (e.g. "ext3" or "VFAT" above)

Fourth column: Mount parameters (see Help man Mount)

Fifth column: Indicate whether to back up, (0 is not a backup, 1 is to be backed up, general root partition to back up)

Sixth column: Indicates the self-test order. (0 is not self-test, 1 or 2 is to self-test, if the root partition to be set to 1, the other partition can only be 2)
