《如何在lvm映射的裸设备上安装Oracle数据库》要点：
本文介绍了如何在lvm映射的裸设备上安装Oracle数据库，希望对您有用。如果有疑问，可以联系我们。
本文主要介绍了Oracle 10g在lvm映射的裸设备上的安装过程,包括创建磁盘分区、创建PV、创建VG、创建相关的lv、以及裸设备配置文件的更改等,希望能够对您有所帮助.
Oracle 10g在lvm映射的裸设备上的安装过程,需要创建PV、VG以及相应的lv等操作,本文主要介绍了这一安装过程,接下来就让我们一起去了解一下吧.
安装过程如下：
1. 创建磁盘分区
分别对/dev/sdc /dev/sdd /dev/sde分区
例如：
#fdisk /dev/sdc
2. 创建pv(pvcreate)
[root@localhost ~]# pvcreate /dev/sdc1
Physical volume “/dev/sdc1” successfully created
[root@localhost ~]# pvcreate /dev/sdd1
Physical volume “/dev/sdd1” successfully created
[root@localhost ~]# pvcreate /dev/sde1
Physical volume “/dev/sde1” successfully created
[root@localhost ~]# pvs
PV VG Fmt Attr PSize PFree
/dev/sda2 VolGroup00 lvm2 a- 9.88G 64.00M
/dev/sdb1 VolGroup00 lvm2 a- 9.97G 0
/dev/sdc1 lvm2 — 10.00G 10.00G
/dev/sdd1 lvm2 — 10.00G 10.00G
/dev/sde1 lvm2 — 10.00G 10.00G
3. 创建VG(vgcreate)
[root@localhost ~]# vgcreate VolOracle /dev/sdc1 /dev/sdd1 /dev/sde1
Volume group “VolOracle” successfully created
[root@localhost ~]# vgs
VG #PV #LV #SN Attr VSize VFree
VolGroup00 2 2 0 wz–n- 19.84G 64.00M
VolOracle 3 0 0 wz–n- 29.99G 29.99G
4. 创建相关的lv,oracle默认的这些
spfile 10M
control1 50M
control2 50M
control3 50M
redo1_1 200M
redo2_1 200M
redo3_1 200M
system01 1024M
sysaux01 1024M
infodb 3096M
temp 500M
users 200M
undotbs 500M
[root@localhost ~]# lvcreate -L 10M -n spfile VolOracle
Rounding up size to full physical extent 12.00 MB
Logical volume “spfile” created
[root@localhost ~]# lvcreate -L 50M -n control1 VolOracle
Rounding up size to full physical extent 52.00 MB
Logical volume “control1” created
[root@localhost ~]# lvcreate -L 50M -n control2 VolOracle
Rounding up size to full physical extent 52.00 MB
Logical volume “control2” created
[root@localhost ~]# lvcreate -L 50M -n control3 VolOracle
Rounding up size to full physical extent 52.00 MB
Logical volume “control3” created
[root@localhost ~]# lvcreate -L 200M -n redo1_1 VolOracle
Logical volume “redo1_1” created
[root@localhost ~]# lvcreate -L 200M -n redo2_1 VolOracle
Logical volume “redo2_1” created
[root@localhost ~]# lvcreate -L 200M -n redo3_1 VolOracle
Logical volume “redo3_1” created
[root@localhost ~]# lvcreate -L 1024M -n system01 VolOracle
Logical volume “system01” created
[root@localhost ~]# lvcreate -L 1024M -n sysaux01 VolOracle
Logical volume “sysaux01” created
[root@localhost ~]# lvcreate -L 3096M -n infodb VolOracle
Logical volume “infodb” created
[root@localhost ~]# lvcreate -L 500M -n temp VolOracle
Logical volume “temp” created
[root@localhost ~]# lvcreate -L 200M -n users VolOracle
Logical volume “users” created
[root@localhost ~]# lvcreate -L 500M -n undotbs1 VolOracle
Logical volume “undotbs1” created
5. 把刚创建的lv映射成裸设备
配置/etc/sysconfig/rawdevices
注意：对应linux下的/etc/raw 修改的格式也稍不同 rawX:DG_NAME/VOL_NAME
# raw device bindings
# format:
#
# example: /dev/raw/raw1 /dev/sda1
# /dev/raw/raw2 8 5

/dev/raw/raw15 /dev/mapper/VolOracle-redo2_2
/dev/raw/raw16 /dev/mapper/VolOracle-redo3_2
[root@localhost etc]# raw -qa
[root@infodb sysconfig]# service rawdevices restart
