linux如何初始化硬盘,Linux硬盘简易初始化(LVM)

Step 1:

用parted对磁盘进行分区：

[[email protected] ~]# parted /dev/sdb

进行分区，开启LVM：

(parted) mklabel gpt

(parted) mkpart primary xfs 0% 100%

(parted) set 1 lvm on

(parted)

扫描一次，让分区立即生效：

Step 2:

将添加磁盘进行LVM划分：

[[email protected] ~]# pvcreate /dev/sdb1

Physical volume "/dev/sdb1" successfully created.

[[email protected] ~]# vgcreate yunvg /dev/sdb1

Volume group "yunvg" successfully created

[[email protected] ~]# vgdisplay

[[email protected] ~]# lvcreate -L 999.99GB -n YunDisk yunvg

Rounding up size to full physical extent 999.99 GiB

Logical volume "YunDisk" created.

[[email protected] Exdisk]# lvcreate -l 100%FREE -n exdisk1 exdisk

Step 3:

格式化磁盘，用XFS格式：

[[email protected] ~]# mkfs.xfs /dev/yunvg/YunDisk

meta-data=/dev/yunvg/YunDisk isize=512 agcount=4, agsize=65535488 blks

= sectsz=512 attr=2, projid32bit=1

= crc=1 finobt=0, sparse=0

data = bsize=4096 blocks=262141952, imaxpct=25

= sunit=0 swidth=0 blks

naming =version 2 bsize=4096 ascii-ci=0 ftype=1

log =internal log bsize=4096 blocks=127999, version=2

= sectsz=512 sunit=0 blks, lazy-count=1

realtime =none extsz=4096 blocks=0, rtextents=0

[[email protected] ~]

Step 4:

将磁盘挂接到指定的目录，并设置开机自动挂接：

[[email protected] /]# mkdir /Exdisk

[[email protected] /]# mount -t xfs /dev/yunvg/YunDisk /Exdisk/

[[email protected] /]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/mapper/cl-root 16G 1.8G 15G 12% /

devtmpfs 3.9G 0 3.9G 0% /dev

tmpfs 3.9G 0 3.9G 0% /dev/shm

tmpfs 3.9G 8.5M 3.9G 1% /run

tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup

/dev/sda2 235M 119M 117M 51% /boot

tmpfs 783M 0 783M 0% /run/user/0

/dev/mapper/yunvg-YunDisk 1000G 33M 1000G 1% /Exdisk

[[email protected] /]# vim /etc/fstab

[[email protected] ~]#

以上为简易快速的挂接新硬盘。
