parted?命令實戰案例
========================================================
(1)既適用於gpt格式，又適用於mbr格式。
(2)單個文件在2T以上，需要使用parted來分區。
主要內容：
============================================
一、使用parted 進行分區
二、創建生產上使用的parted分區的步驟
============================================
一、使用parted 進行分
[root@db01 /]# parted /dev/sdd ###使用parted 對/dev/sdd進行分區
GNU Parted 2.1 ### parted的版本
Using /dev/sdd ### parted 執行操作的磁盤
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) p ### 顯示當前磁盤的分區
Model: VMware, VMware Virtual S (scsi) ###磁盤的信息，虛擬的scsi磁盤
Disk /dev/sdd: 1074MB ###磁盤的大小
Sector size (logical/physical): 512B/512B ###扇區大小
Partition Table: msdos ###當前磁盤分區表標簽msdos
Number Start End Size File system Name Flags
(parted) mklabel ###創建磁盤分區標簽
New disk label type? gpt ###設置磁盤分區標簽為gpt
Warning: The existing disk label on /dev/sdd will be destroyed and all data on this disk will be lost. Do you want to
continue?
Yes/No? y ###繼續
(parted) mkpart oracle 0 -1 ####創建磁盤分區從0開始，-1代表剩余全部。若為數值，如100 表示分區大小100M
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel? i ###忽略警告
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sdd: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags ###新建分區信息
1 17.4kB 1073MB 1073MB oracle
(parted) mkpart ###交互式創建parted分區
Partition name? []? test ###分區名稱
File system type? [ext2]? ext2 ###分區格式
Start? 1
End? 2
Warning: You requested a partition from 1000kB to 2000kB.
The closest location we can manage is 1073MB to 1073MB.
Is this still acceptable to you?
Yes/No? y
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel? i
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sdd: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 17.4kB 1073MB 1073MB oracle
2 1073MB 1073MB 512B test
(parted) rm 2
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sdd: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 17.4kB 1073MB 1073MB oracle
(parted) q
Information: You may need to update /etc/fstab.
二、創建生產上使用的parted分區的步驟
【適用場景】如果Oracle 數據庫需要添加10T備份空間，使用parted添加
步驟一：指定需要創建parted分解的存儲設備
[root@db01 /]# parted /dev/sdd
GNU Parted 2.1
Using /dev/sdd
Welcome to GNU Parted! Type 'help' to view a list of commands.
步驟二：查看當前parted分區情況
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sdd: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
步驟三：創建parted的分區標簽
(parted) mklabel
New disk label type? gpt
Warning: The existing disk label on /dev/sdd will be destroyed and all data on this disk will be lost. Do you want to
continue?
Yes/No? yes
步驟四： 創建parted的分區
(parted) mkpart oracle 0 -1
Warning: The resulting partition is not properly aligned for best performance.
Ignore/Cancel? i
(parted) p
Model: VMware, VMware Virtual S (scsi)
Disk /dev/sdd: 1074MB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Number Start End Size File system Name Flags
1 17.4kB 1073MB 1073MB oracle
(parted) q
Information: You may need to update /etc/fstab.
步驟五：對parted分區進行格式化
[root@db01 /]# mkfs.ext4 /dev/sdd1
mke2fs 1.41.12 (17-May-2010)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
Stride=0 blocks, Stripe width=0 blocks
65536 inodes, 261895 blocks
13094 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=268435456
8 block groups
32768 blocks per group, 32768 fragments per group
8192 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376
Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 22 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@db01 /]#
步驟六：掛載parted分區
[root@db01 /]# mount /dev/sdd1 /alexpeng/
[root@db01 /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda3 45G 4.4G 39G 11% /
tmpfs 1004M 0 1004M 0% /dev/shm
/dev/sda1 485M 39M 421M 9% /boot
/dev/sdb2 79G 184M 75G 1% /oracle
/dev/sdb1 20G 172M 19G 1% /soft
/dev/sdd1 1007M 18M 939M 2% /alexpeng
[root@db01 /]#
[root@db01 /]#
[root@db01 /]# mount
/dev/sda3 on / type ext4 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
tmpfs on /dev/shm type tmpfs (rw,rootcontext="system_u:object_r:tmpfs_t:s0")
/dev/sda1 on /boot type ext4 (rw)
/dev/sdb2 on /oracle type ext4 (rw)
/dev/sdb1 on /soft type ext4 (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
/dev/sdd1 on /alexpeng type ext4 (rw)
步驟七：設置開啟分區自啟動
[root@db01 /]# vi /etc/fstab ###添加如下信息
/dev/sdd1 /alexpeng ext4 defaults 0 0
[root@db01 /]# umount /alexpeng/
[root@db01 /]# mount /alexpeng/
