1. All nodes as root
rpm -ivh oracleasmlib-2.0.4-1.el6.x86_64.rpm
rpm -qa *asm*
kmod-oracleasm-2.0.8-13.0.1.el6_8.x86_64
oracleasm-support-2.1.8-1.el6.x86_64
oracleasmlib-2.0.4-1.el6.x86_64
rpm -qa cvu*
cvuqdisk-1.0.9-1.x86_64
2.装完上述必备的rpm之后就可以开始配置asmlib了
Configure ASMLib by running the following on all nodes:
sudo /etc/init.d/oracleasm configure
Default user to own the driver interface []: oracle
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y
Writing Oracle ASM library driver configuration: done
Initializing the Oracle ASMLib driver: [ OK ]
Scanning the system for Oracle ASMLib disks: [ OK ]
3.Modify ASM config file (root) all nodes (Alredy done by Linux team) - Validate this.
[[email protected] ~]$ cat /etc/sysconfig/oracleasm-_dev_oracleasm
ORACLEASM_ENABLED=true
ORACLEASM_UID=oracle
ORACLEASM_GID=dba
ORACLEASM_SCANBOOT=true
ORACLEASM_SCANORDER="dm"
ORACLEASM_SCANEXCLUDE="sd"
ORACLEASM_USE_LOGICAL_BLOCK_SIZE=false
4.重启asmlib服务
sudo /etc/init.d/oracleasm stop
sudo /etc/init.d/oracleasm start
5.create disk：
sudo fdisk -l|grep -i mapper|grep -i GB
Disk /dev/mapper/mpathl: 12.9 GB, 12885688320 bytes
Disk /dev/mapper/mpathn: 12.9 GB, 12885688320 bytes
Disk /dev/mapper/mpathm: 12.9 GB, 12885688320 bytes
Disk /dev/mapper/mpathe: 274.9 GB, 274879610880 bytes
Disk /dev/mapper/mpathj: 21.5 GB, 21475491840 bytes
Disk /dev/mapper/mpathf: 274.9 GB, 274879610880 bytes
Disk /dev/mapper/mpathc: 107.4 GB, 107375493120 bytes
Disk /dev/mapper/mpathk: 21.5 GB, 21475491840 bytes
Disk /dev/mapper/mpathg: 274.9 GB, 274879610880 bytes
Disk /dev/mapper/mpathi: 274.9 GB, 274879610880 bytes
Disk /dev/mapper/mpathd: 214.7 GB, 214749020160 bytes
Disk /dev/mapper/mpathh: 274.9 GB, 274879610880 bytes
Disk /dev/mapper/mpatha: 85.9 GB, 85900001280 bytes
把这几块盘利用asmlib createdisk建成可供asm使用的candidate磁盘
sudo /usr/sbin/oracleasm createdisk OCR_VTE01 /dev/mapper/mpathl
sudo /usr/sbin/oracleasm createdisk OCR_VTE02 /dev/mapper/mpathn
sudo /usr/sbin/oracleasm createdisk OCR_VTE03 /dev/mapper/mpathm
sudo /usr/sbin/oracleasm createdisk DSK01 /dev/mapper/mpathe
sudo /usr/sbin/oracleasm createdisk DSK02 /dev/mapper/mpathf
sudo /usr/sbin/oracleasm createdisk DSK03 /dev/mapper/mpathg
sudo /usr/sbin/oracleasm createdisk DSK04 /dev/mapper/mpathh
sudo /usr/sbin/oracleasm createdisk DSK05 /dev/mapper/mpathi
sudo /usr/sbin/oracleasm createdisk DSK06 /dev/mapper/mpathj
sudo /usr/sbin/oracleasm createdisk DSK07 /dev/mapper/mpathk
sudo /usr/sbin/oracleasm listdisks
sudo /usr/sbin/oracleasm-discover
Run The below on other nodes:
sudo /usr/sbin/oracleasm scandisks
sudo /usr/sbin/oracleasm listdisks
sudo /usr/sbin/oracleasm-discover
关于前期的准备工作做到这里也差不多了，下次就是开始集群的安装了。
本节讲的主要是asmlib的安装配置以及把需要用到的磁盘建成可供asm使用的磁盘。
