Linux：parted 磁碟分割

之前拿來做快照備份的硬碟掛了，趕緊換上一顆
以前都用fdisk，簡單好用，現在為處理大容量GPT格式須改用parted，稍稍複雜一些些。
參閱：Linux 的 Parted 指令教學：建立、變更與修復磁碟分割區。開始分割、格式化吧！

$sudo parted
 )help

   align-check TYPE N                        check partition N for TYPE(min|opt) alignment
   help [COMMAND]                           print general help, or help on COMMAND
   mklabel,mktable LABEL-TYPE               create a new disklabel (partition table)
   mkpart PART-TYPE [FS-TYPE] START END     make a partition
   name NUMBER NAME                         name partition NUMBER as NAME
   print [devices|free|list,all|NUMBER]     display the partition table, available devices, free
         space, all found partitions, or a particular partition
   quit                                     exit program
   rescue START END                         rescue a lost partition near START and END
 resizepart NUMBER END                    resize partition NUMBER
   rm NUMBER                                delete partition NUMBER
   select DEVICE                            choose the device to edit
   disk_set FLAG STATE                      change the FLAG on selected device
   disk_toggle [FLAG]                       toggle the state of FLAG on selected device
   set NUMBER FLAG STATE                    change the FLAG on partition NUMBER
   toggle [NUMBER [FLAG]]                   toggle the state of FLAG on partition NUMBER
   unit UNIT                                set the default unit to UNIT
   version                                  display the version number and copyright information of
         GNU Parted

 我要切的是/dev/sdb 空硬碟 PS.一開始也可以像fdisk用法，後直接接device
 )select /dev/sdb

 因我硬碟只有800G(VM)，所以做一般MBR格式也無妨
 )mklabel msdos
 )mkpart
 Partition type?  primary/extended? p                                      
 File system type?  [ext2]?  (預設不用動，到時自行格式化就好)                                     
 Start? 1                                                                  
 End? -1  (全給)

 看一下結果
 )print
 Model: VMware Virtual disk (scsi)
 Disk /dev/sdb: 859GB
 Sector size (logical/physical): 512B/512B
 Partition Table: msdos
 Disk Flags: 
 Number  Start   End    Size   Type     File system  Flags
  1      1049kB  859GB  859GB  primary

 離開
 )quit

 格式化為btrfs
 $sudo mkfs.btrfs /dev/sdb1

 取得UUID
 $sudo blkid

 建立資料夾(快照備份用)
 $sudo mkdir /btrfs

 掛載
 $sudo vim /etc/fstab
 UUID=luckylucky-8888-66666-168168-abcde123456 /btrfs   btrfs   defaults   0 0
 $sudo mount -a

完成，samba、SELinux、acl、snapper得重弄了吧！？睡了，明日再進行
