5,可見parted預設是定位第一個磁碟/dev/sda
[root@mygirl ~]# parted

Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print

(parted) quit                                                             
[root@mygirl ~]# 


6,根據上述第3個命令可見parted命令的用法以及上述命令的結構分類
檢視parted命令
[root@mygirl ~]# parted --help
Usage: parted [OPTION]... [DEVICE [COMMAND [PARAMETERS]...]...]
Apply COMMANDs with PARAMETERS to DEVICE.  If no COMMAND(s) are given, run in
interactive mode.




7，parted /dev/sdc可以定位指定的磁碟，然後help會顯示對應的具體命令


[root@mygirl ~]# parted /dev/sdc
GNU Parted 2.1
Using /dev/sdc
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) help                                                             
  align-check TYPE N                        check partition N for TYPE(min|opt) alignment

  cp [FROM-DEVICE] FROM-NUMBER TO-NUMBER   copy file system to another partition
  help [COMMAND]                           print general help, or help on COMMAND
  mklabel,mktable LABEL-TYPE               create a new disklabel (partition table)

  version                                  display the version number and copyright information of GNU Parted
(parted)     




8,檢視mkpart建立分割槽的用法
(parted) help mkpart                                                      
  mkpart PART-TYPE [FS-TYPE] START END     make a partition


        PART-TYPE is one of: primary, logical, extended
        FS-TYPE is one of: ext4, ext3, ext2, fat32, fat16, hfsx, hfs+, hfs, jfs, swsusp, linux-swap(v1), linux-swap(v0), ntfs, reiserfs, hp-ufs, sun-ufs, xfs, apfs2, apfs1, asfs,
        amufs5, amufs4, amufs3, amufs2, amufs1, amufs0, amufs, affs7, affs6, affs5, affs4, affs3, affs2, affs1, affs0, linux-swap, linux-swap(new), linux-swap(old)
        START and END are disk locations, such as 4GB or 10%.  Negative values count from the end of the disk.  For example, -1s specifies exactly the last sector.
        
        'mkpart' makes a partition without creating a new file system on the partition.  FS-TYPE may be specified to set an appropriate partition ID.
(parted)     




9，建立磁碟分割槽，但報錯如下
(parted) mkpart primary                                                   
Error: /dev/sdc: unrecognised disk label  




10，據以上分析，可能還要進行其它的配置，檢視mklabel命令
(parted) help mklabel                                                     
  mklabel,mktable LABEL-TYPE               create a new disklabel (partition table)


        LABEL-TYPE is one of: aix, amiga, bsd, dvh, gpt, mac, msdos, pc98, sun, loop  






11，使用mklabel建立磁碟標籤
(parted) mklabel msdos  




12，無法預先知道開始及結束的柱面編號 
(parted) mkpart primary                                                   
File system type?  [ext2]? ext4                                           
Start? 1                                                                  
End?                                                                      
End?                                                                      
End?                                                                      
End? ^C                                                                   
(parted)    




(parted) print                                                            
Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sdc: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos


Number  Start  End  Size  Type  File system  Flags




13,進行對比分析法獲取磁碟分割槽之開始及結束的含義
(parted) mkpart primary ext4 1 100




14，檢視磁碟所有的磁碟分割槽資訊，可見開始及結束是以M為單元的
(parted) print                                                            
Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sdc: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos


Number  Start   End     Size    Type     File system  Flags
 1      1049kB  99.6MB  98.6MB  primary




 15，使用rm 刪除某個磁碟分割槽
 (parted) rm 1 


 (parted) print                                                            
Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sdc: 2147MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos


Number  Start  End  Size  Type  File system  Flags


16,基於上述邏輯繼續建立多個磁碟分割槽,可見主分割槽primary不能建立超過4個，如果建立第5個就會報錯
(parted) mkpart primary 1 300                                             
(parted) print

(parted) mkpart primary 451 453                                           
(parted) mkpart primary 454 455                                           
Error: Can't create any more partitions.                                  
(parted)                




(parted) print

 3      401MB   450MB  49.3MB  primary
 4      451MB   453MB  2097kB  primary




17，不以基於第4個主分割槽primary建立邏輯分割槽或者擴充套件分割槽
(parted) help mkpart                                                      
  mkpart PART-TYPE [FS-TYPE] START END     make a partition


        PART-TYPE is one of: primary, logical, extended
        FS-TYPE is one of: ext4, ext3, ext2, fat32, fat16, hfsx, hfs+, hfs, jfs, swsusp, linux-swap(v1), linux-swap(v0), ntfs, reiserfs, hp-ufs, sun-ufs, xfs, apfs2, apfs1, asfs,
        amufs5, amufs4, amufs3, amufs2, amufs1, amufs0, amufs, affs7, affs6, affs5, affs4, affs3, affs2, affs1, affs0, linux-swap, linux-swap(new), linux-swap(old)
        START and END are disk locations, such as 4GB or 10%.  Negative values count from the end of the disk.  For example, -1s specifies exactly the last sector.
        
        'mkpart' makes a partition without creating a new file system on the partition.  FS-TYPE may be specified to set an appropriate partition ID.
(parted)   




(parted) mkpart logical 455 480                                           
Error: Can't create any more partitions. 




(parted) mkpart extended 455 480                                          
Error: Can't create any more partitions.






18，可以基於第3個主分割槽然後馬上建立擴充套件分割槽extended
(parted) rm 4
(parted) print

 (parted) mkpart extended 451 500

(parted) print

 4      451MB   500MB  49.3MB  extended               lba




19,基於擴充套件分割槽建立的邏輯分割槽不能建立大小，否則會報錯如下影響效能，當然你可以忽略這個提示
(parted) mkpart logical 452 480

20,可見擴充套件分割槽是父分割槽，而邏輯分割槽是子分割槽，即後者只能基於或依賴於前者，且後者邏輯分割槽的空間範圍只能位於所屬擴充套件分割槽的空間範圍
(parted) mkpart logical 500 501

23，可見只要刪除擴充套件分割槽，會一併把下屬的邏輯分割槽全部刪除
(parted) rm 4

24，可見只能建立一個擴充套件分割槽，不能建立多個擴充套件分割槽
(parted) mkpart extended 451 500

25,由下可知，主分割槽為第1到第4，從第5之後為邏輯分割槽

26，mkfs好像不能指定磁碟分割槽編號進行劃分檔案系統,而且可以指定的檔案系統特別少，頂多到ext2,我分析可能是parted的版本太老了可能

27,check 用於檢查磁碟分割槽的檔案系統，但parted不建議使用它，而應使用e2fsck檢查檔案系統

30，使用mklabel已經配置了分割槽表後，然後再次執行mklabel，之前的分割槽表以及磁碟分割槽資訊全部會丟失，所以一定要小心仔細 


清除之前MSDOS的磁碟分割槽表，然後重新建立GPT磁碟分割槽表
