HP-UNIX如何创建文件系统_好文资源

本篇文章为大家展示了HP-UNIX如何创建文件系统，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

HP-UNIX 创建文件系统

1.系统环境

# uname -a

HP-UX callcdb2 B.11.31 U ia64

2.查看VG组

# ll /dev/vg*/group

crw-r—– 1 root sys 64 0x000000 Jun 9 12:13 /dev/vg00/group

3.创建物理卷

# pvcreate /dev/rdisk/disk162

Physical volume “/dev/rdisk/disk162” has been successfully created.

4.创建VG

4-1.创建VG组名

# mkdir /dev/vg_cdc

# ll /dev/vg*/group

crw-r—– 1 root sys 64 0x000000 Jun 9 12:13 /dev/vg00/group

4-2.给与VG组唯一的0x010000

# mknod /dev/vg_cdc/group c 开发云主机域名64 0x010000

# ll /dev/vg*/group

crw-r—– 1 root sys 64 0x000000 Jun 9 12:13 /dev/vg00/group

crw-r–r– 1 root sys 64 0x010000 Aug 18 14:19 /dev/vg_cdc/group

4-3.创建VG组并写入配置文件

# vgcreate -s 32 /dev/vg_cdc /dev/disk/disk162

Increased the number of physical extents per physical volume to 1599.

Volume group “/dev/vg_cdc” has been successfully created.

Volume Group configuration for /dev/vg_cdc has been saved in /etc/lvmconf/vg_cdc.conf

5.创建LV并指定LV大小

# lvcreate -L 40000 -n lv_cdc vg_cdc

Logical volume “/dev/vg_cdc/lv_cdc” has been successfully created with

character device “/dev/vg_cdc/rlv_cdc”.

Logical volume “/dev/vg_cdc/lv_cdc” has been successfully extended.

6.格式化

# newfs -F vxfs -o l开发云主机域名argefiles /dev/vg_cdc/rlv_cdc

version 7 layout

40960000 sectors, 40960000 blocks of size 1024, log size 65536 blocks

largefiles supported

7.创建挂载点

# mkdir /cdc

8.挂载

# mount /dev/vg_cdc/lv_cdc /cdc

附表

1.vgexport vg_cdc –删除VG卷组

2.pvcreate -f /dev/rdisk/disk162 –如果重新创建VG卷组的时候加F参数

3.vgchange -a n(y) vg_cdc –停止或者激活逻辑卷组。
