hp-ux创建lv实例
1. vgdisplay查看卷组
[root@jcsrv2:/]# vgdisplay
--- Volume groups ---
VG Name /dev/vg00

Max LV 255
Cur LV 8

2. 在vg00卷组中 创建 一个10M的 名字 为xyy的逻辑卷
[root@jcsrv2:/]# l
vcreate -L 10 -n xyy /dev/vg00/xyy
lvcreate: Volume group "/dev/vg00/xyy" does not exist in the "/etc/lvmtab" file.
[root@jcsrv2:/]# lvcreate -L 10 -n xyy /dev/vg00
Warning: rounding up logical volume size to extent boundary at size "16" MB.
Logical volume "/dev/vg00/xyy" has been successfully created with
character device "/dev/vg00/rxyy".
Logical volume "/dev/vg00/xyy" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
3.查看是否存在 xyy 逻辑卷
[root@jcsrv2:/]# lvdisplay /dev/vg00/xyy
--- Logical volumes ---
LV Name /dev/vg00/xyy
VG Name /dev/vg00
LV Permission read/write
LV Status available/syncd
Mirror copies 0
Consistency Recovery MWC
Schedule parallel
LV Size (Mbytes) 16
Current LE 2
Allocated PE 2
Stripes 0
Stripe Size (Kbytes) 0
Bad block on
Allocation strict
IO Timeout (Seconds) default
4.为 /dev/vg00/xyy 逻辑卷 创建文件
系统
newfs -F vxfs /dev/vg00/rxyy
5. mkdir /xyy //创建一个挂载点
6. mount /dev/vg00/xyy /xyy //挂载新创建的文件系统
7.bdf //进行查看
[root@jcsrv2:/]# bdf
Filesystem kbytes used avail %used Mounted on

[root@jcsrv2:/]#
vi /etc/fstab --让其开机生效
/dev/vgbak/lv_data2 /data2 vxfs delaylog 0 2
8.umount /xyy //取消挂载
9. lvremove /dev/vg00/xyy //删除 /dev/vg00/xyy 逻辑卷
[root@jcsrv2:/]# lvremove /dev/vg00/xyy
The logical volume "/dev/vg00/xyy" is not empty;
do you really want to delete the logical volume (y/n) : y
Logical volume "/dev/vg00/xyy" has been successfully removed.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf
10. [root@jcsrv2:/]# lvdisplay /dev/vg00/xyy
lvdisplay: "/dev/vg00/xyy": No such file or directory
//发现已经不存在了
1、--创建3T的LV，名字:lv_data2
lvcreate -L 3000000 -n lv_data2 /dev/vgbak
1、--创建3T的LV，名字:lv_data2
lvcreate -L 3000000 -n lv_data2 /dev/vgbak
2、--创建文件系统
newfs -F vxfs /dev/vgbak/rlv_data2
newfs -F vxfs /dev/vgbak/rlv_data2
3、--创建挂载点
mkdir /data2
mkdir /data2
4、--将文件系统挂载到LV上
mount /dev/vgbak/lv_data2 /data2
mount /dev/vgbak/lv_data2 /data2
5、--设置开机自动挂载
vi /etc/fstab
vi /etc/fstab
6、--在最下面添加如下：
/dev/vgbak/lv_data2 /data2 vxfs delaylog 0 2
/dev/vgbak/lv_data2 /data2 vxfs delaylog 0 2
