Linux4.3 parted partitioned GPT format

The Fdisk partitioning tool, which has a partition format of MBR, is characterized by a maximum of 4 primary partitions and a disk size not exceeding 2T. and the GPT partition format, break through these restrictions, it does not have a primary partition, extended partition, logical partition of the points, on a disk can be divided into 128 partitions, support more than 2T partition, the maximum volume up to 18EB.　

　　Parted tools Common features:

When entering parted on the command line, enter the interactive mode of the parted command. Enter Help to display the assistance information. The following is a brief introduction of the commonly used functions 1, check the file system simple. It is recommended to check the file system with other commands, such as Fsck2, help display helper Information 3, Mklabel create partition table, that is, use MSDOS (MBR) or GPT, or other way partition Table 4, MKFS create file system. The command does not support the EXT3 format, so it is recommended that you do not use it, preferably with parted, and then exit parted interactive mode, partitioning with other commands such as Mkfs.ext35, Mkpart to create a new partition. Format: Mkpart part-type [Fs-type] The START endpart-type type mainly has primary (primary partition), extended (extended partition), logical (logical zone). Extended partitions and logical partitions are only for MSDOS. Fs-type file system type, mainly has the start and end position of the start end partition such as FS32,NTFS,EXT2,EXT3. 6, Mkpartfs establish the partition and its file system. The ext3 file system is not currently supported and is not recommended for use. Finally, after the area is divided, exit parted and then use other commands to create the file system. 7, print output partition information. This feature has 3 options, free displays all information about the disk, and displays the amount of space left for the specified partition. All displays all disk information 8, resize adjusts the size of the specified partition. Currently support for EXT3 format is not very good, so it is not recommended to use this feature. 9, rescue recover accidentally deleted partition. If you accidentally delete a partition with the parted RM command, you can recover through the rescue feature. You need to give the location of the start and end of the partition when recovering. The parted is then searched within a given range and prompts to recover the partition. 10, RM delete partition. The command format is RM number. For example, RM 3 is to delete the partition numbered 3 11, select Device. When you enter the parted command and enter the interactive mode, if you have more than one hard disk, select the hard drive you want to operate with select. such as: SELECT/DEV/SDB12, set flag. Change the flag for the specified partition number. The flags are usually as follows: Boot hidden raid LVM, etc. Boot is boot partition, hidden is hidden partition, RAID soft RAID,LVM is logical partition. Example: Set 3 Boot on setting partition number 3 is the boot partition note: The above content is commonly used in parted, because the tool is currently not very good for ext3 support, so some features can not be applied, such as move (mobile partition) and resize.
