1、fdisk -l 查看分区
2、fdisk /dev/xvde 开始分区操作
3、pvcreate 创建物理卷
[root@localhost ~]# pvcreate /dev/xvde1WARNING: ext4 signature detected on /dev/xvde1 at offset 1080. Wipe it? [y/n]: yWiping ext4 signature on /dev/xvde1.Physical volume "/dev/xvde1" successfully created.You have mail in /var/spool/mail/root
4、pvscan 扫描物理卷
[root@localhost ~]# pvscanPV /dev/xvda2 VG centoslvm2 [<99.00 GiB / 4.00 MiB free]PV /dev/xvde1 lvm2 [<100.00 GiB]Total: 2 [<199.00 GiB] / in use: 1 [<99.00 GiB] / in no VG: 1 [<100.00 GiB]
5、vgcreate 创建卷组 （pro 为 组名 可自定义）
[root@localhost ~]# vgcreate pro /dev/xvde1Volume group "kgc" successfully created
6、vgdisplay显示卷组信息
[root@localhost ~]# vgdisplay--- Volume group ---VG NamekgcSystem ID Formatlvm2Metadata Areas 1Metadata Sequence No 1VG Access read/writeVG Status resizableMAX LV0Cur LV0Open LV0Max PV0Cur PV1Act PV1VG Size<100.00 GiBPE Size4.00 MiBTotal PE 25599Alloc PE / Size 0 / 0 Free PE / Size 25599 / <100.00 GiBVG UUIDic9S1N-axit-nuWT-urpf-3NVw-ctpQ-I729Cb
7、lvcreate 创建逻辑卷 （99G 为创建大小，project为卷名，pro 为上面的组名）
[root@localhost ~]# lvcreate -L 99G -n project proLogical volume "project" created.
8、lvdisplay 显示逻辑卷信息
[root@localhost ~]# lvdisplay--- Logical volume ---LV Path/dev/pro/projectLV NameprojectVG NamekgcLV UUIDUWZyj6-VPSo-KASI-tD13-69lh-B3KY-KdW47oLV Write Access read/writeLV Creation host, time localhost.localdomain, -12-24 16:47:26 +0800LV Status available# open 0LV Size99.00 GiBCurrent LE 25344Segments1Allocation inheritRead ahead sectorsauto- currently set to8192Block device 253:3
9、增加开机自动挂载配置(见 新增加一行 里配置 其中/dev/pro/project 为逻辑卷 路径/project 为自定义路径 )
[root@localhost ~]# vim /etc/fstab## /etc/fstab# Created by anaconda on Tue Oct 23 17:28:09 ## Accessible filesystems, by reference, are maintained under '/dev/disk'# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info#/dev/mapper/centos-root / xfsdefaults 0 0UUID=6c4588cb-b621-486f-9190-9989fa82ab45 /boot xfsdefaults 0 0/dev/mapper/centos-home /home xfsdefaults 0 0/dev/mapper/centos-swap swapswap defaults 0 0#新增加一行/dev/pro/project /projectxfsdefaults 0 0
10、mount -a 启动所有挂载，无需重启
[root@localhost ~]# mount -a
11、df -lh 查看挂载详细信息（见最后一行发现分区挂载成功）
[root@localhost ~]# df -lhFilesystem TypeSize Used Avail Use% Mounted ondevtmpfsdevtmpfs 7.8G0 7.8G 0% /devtmpfs tmpfs7.8G0 7.8G 0% /dev/shmtmpfs tmpfs7.8G 9.3M 7.8G 1% /runtmpfs tmpfs7.8G0 7.8G 0% /sys/fs/cgroup/dev/mapper/centos-root xfs 50G 5.1G 45G 11% //dev/xvda1 xfs1014M 201M 814M 20% /boot/dev/mapper/centos-home xfs 46G 33M 46G 1% /hometmpfs tmpfs1.6G0 1.6G 0% /run/user/0tmpfs tmpfs60M0 60M 0% /var/log/rtlog/dev/mapper/pro-project xfs 99G 33M 99G 1% /project
