标题: HP-UX操作系统下在线扩展文件系统实验成功
操作系统为BOE环境，默认是不带OnLineJFS套件，必须额外安装。

[/]#swlist | grep -i hpux11i
  HPUX11i-BOE                B.11.31.0809 HP-UX Base Operating Environment

安装OnLineJFS过程如下：

1)上传安装包到目标主机

[~]$ ls -l
总用量 349980
-rw-r--r--  1 test  test 129229616  2月 14 17:32 MirrorDisk.tar.gz
-rw-r--r--  1 test  test 228786074  2月 13 16:53 OnLineJFS.tar.gz
[~]$
[~]$ ftp xx.xx.xx.xx

2)把OnLineJFS.tar.gz解压到/tmp/OnLineJFS目录下

[/]#ls -l /tmp/OnLineJFS
total 304
dr-x------ 2 root    sys          96 Feb 13 15:51 B3929EA
dr-x------ 2 root    sys          96 Feb 13 15:51 Base-VXFS

dr-x------ 6 root    sys          8192 Feb 13 15:55 JFS
dr-x------ 8 root    sys          8192 Feb 13 15:51 Networking
dr-x------  10 root    sys          8192 Feb 13 15:54 OS-Core
dr-x------ 3 root    sys          96 Feb 13 15:58 OnlineJFS
......
......

3)安装

[/]#swinstal -s /tmp/OnLineJFS

4)查看安装是否成功

[/]#swlist | grep -i online
  B3929EA                      B.11.31       HP OnLineJFS (Server)
  OnlineDiag                   B.11.31.04.05  HPUX 11.31 Support Tools Bundle, September 2008

下面以在线扩展/home文件系统为例说明操作过程：

1)查看/home文件系统对应的LV名称

[/]#bdf /home
Filesystem       kbytes used avail %used Mounted on
/dev/vg00/lvol4    262144 5792  254360 2% /home

2)查看/dev/vg00/lvol4大小

[/]#lvdisplay /dev/vg00/lvol4 | grep "LV Size"
LV Size (Mbytes)          256

从上面结果可知，/dev/vg00/lvol4逻辑卷大小为256M，现在要扩展到320M

3)先扩展/dev/vg00/lvol4

[/]#lvextend -L 320 /dev/vg00/lvol4
Logical volume "/dev/vg00/lvol4" has been successfully extended.
Volume Group configuration for /dev/vg00 has been saved in /etc/lvmconf/vg00.conf

4)查看LV是否已扩展到320M

[/]#lvdisplay /dev/vg00/lvol4 | grep "LV Size"
LV Size (Mbytes)          320

5)扩展/home文件系统

[/]#fsadm -F vxfs -b 320M /home
vxfs fsadm: V-3-23585: /dev/vg00/rlvol4 is currently 262144 sectors - size will be increased

注：其中的32M是扩展后整个文件系统的大小，也就是LV的大小。

6)查看/home文件系统是否已扩展到320M

[/]#bdf /home
Filesystem       kbytes used avail %used Mounted on
/dev/vg00/lvol4    327680 5800  319376 2% /home

由上可知，在线扩展成功。

/也可以在线扩？

作者: 五“宅”一生 时间: 2009-02-16 20:50
/需要连续分配，除非能腾出/附近的PE,否则无法在线扩.

不要误导新入的技术人员

学习了

谢谢lz和各位高手

pvdisplay可以看到PE的分布情况,3楼的朋友应该就是把lvol3相邻的lvol4清出来后再扩的/吧,我觉得可行,回头也做个实验试试
