在一台rx2660上安装了oracle 10gr2,安装完成后,发现所安装目录的磁盘空间已经用完,显示如下:
# bdf -s
Filesystem kbytes used avail %used Mounted on

解决方案:
1、增加一块73G的SAS硬盘
2、执行ioscan –C disk,找到新硬盘所在路径为0/1/1/0.0.0.1.0
3、安装文件系统
# insf –eH 0/1/1/0.0.0.1.0
4、建立HPUX分区
(1)创建分区文件如下:
# vi /tmp/partitionfile
3
EFI 500MB
HPUX 100%
HPSP 400MB
(2)分区
#idisk –f /tmp/partitionfile –w /dev/rdsk/c1t1d0
idisk version: 1.31

5.安装磁盘驱动程序
# insf -eC disk
insf: Installing special files for sdisk instance 0 address 0/0/2/1.0.16.0.0
insf: Installing special files for sdisk instance 1 address 0/1/1/0.0.0.0.0
insf: Installing special files for sdisk instance 2 address 0/1/1/0.0.0.1.0
6.检查
# ioscan -funC disk
Class I H/W Path Driver S/W State H/W Type Description
====================================================================================
disk 0 0/0/2/1.0.16.0.0 sdisk CLAIMED DEVICE TEAC DV-28E-N

/dev/dsk/c1t1d0s2 /dev/rdsk/c1t1d0s2
/dev/dsk/c1t1d0s3 /dev/rdsk/c1t1d0s3
#
7.在新分区上建设物理卷
#pvcreate /dev/rdsk/c1t1d0s2
8.新PV加入卷组vg00
#vgextend /dev/vg00 /dev/dsk/c1t1d0s2
9.扩展逻辑卷/dev/vg00/lvol4到9G
#lvextend –L 9000 /dev/vg00/lvol4 /dev/dsk/c1t1d0s2
由于此时lvol4 mount在/home下,不能扩展其文件系统,所以需要进入单用户状态
10.扩展lvol4文件系统
#extendfs –F vxfs /dev/vg00/rlvol4
11.检查无误后,重新启动系统
#mount /home
#bdf | grep home
/dev/vg00/lvol4 9224192 5157408 4035024 56% /home
可以发现此时空间已经为9G,利用率已经降为56%,扩展成功。 |
