xiandian2.4 给cinder和swift分区

1、先添加一块硬盘

[root@compute ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 100G 0 disk
├─sda1 8:1 0 1G 0 part /boot
└─sda2 8:2 0 99G 0 part
├─centos-root 253:0 0 50G 0 lvm /
├─centos-swap 253:1 0 7.9G 0 lvm [SWAP]
└─centos-home 253:2 0 41.1G 0 lvm /home
sdb 8:16 0 20G 0 disk
sr0 11:0 1 4.2G 0 rom

2、

注：因为服务器的硬盘大于2T所以用的parted GTP分区，而本次添加的硬盘容量较小，所以是MBR分区，只能用fdisk分区，但是服务器环境中fdisk是不能划分大于2TB硬盘的分区。所以 有用虚拟机环境的就按照我下面的步骤将分区修改为GTP分区，服务器环境的不需要修改。

[root@compute ~]# parted /dev/sdb
GNU Parted 3.1
Using /dev/sdb
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt
(parted) mkpart cinder 0G 10G
(parted) mkpart swift 10G 20G
(parted) quit

3、格式化

[root@compute ~]# mkfs.xfs /dev/sdb1
meta-data=/dev/sdb1 isize=512 agcount=4, agsize=610304 blks
= sectsz=512 attr=2, projid32bit=1
= crc=1 finobt=0, sparse=0
data = bsize=4096 blocks=2441216, imaxpct=25
= sunit=0 swidth=0 blks
naming =version 2 bsize=4096 ascii-ci=0 ftype=1
log =internal log bsize=4096 blocks=2560, version=2
= sectsz=512 sunit=0 blks, lazy-count=1
realtime =none extsz=4096 blocks=0, rtextents=0
[root@compute ~]# mkfs.xfs /dev/sdb2
