linux命令进入db2 linux命令进入桌面( 五 )

IT技术执行


#mmchlicense server --accept -N node01,node02,node03
#/opt/ibm/db2/v10.5/bin/db2cluster -cfs -add -license
创建nsd：任意node执行
编写newNSD文件内容如下
%nsd:
device=/dev/sdb
nsd=nsd1
usage=dataAndMetadata
#mmcrnsd -F /tmp/newNSD (-v no)
如果报mmcrnsd: Disk device sdb refers to an existing NSD,而使用mmlsnsd 又查找不到相应的nsd,添加-v no可以跳过此验证 。
#mmlsnsd 查看创建的nsd名称，记下，在第3步时需要用到.
创建Cluster File System并挂载
启动所有node,任意node执行
#mmstartup -a
#mmgetstate -a
确保所有node全部启动成功为active
# mmcrfs -T /db2sd_20140401 db2sd_20140401 nsd1(此处的nsd1为第2步的nsd名称)
#mmmount all -a
--曾经出现的错误:mmstartup -a无响应
,查看日志/var/adm/ras/mmfs.log.previous
Tue Apr 1 22:02:11 CST 2014: runmmfs starting
Removing old /var/adm/ras/mmfs.log.* files:
Unloading modules from /lib/modules/3.0.76-0.11-default/extra
runmmfs: The /lib/modules/3.0.76-0.11-default/extra/mmfslinux.ko kernel extension does not exist.
runmmfs: Unable to verify kernel/module configuration.
Loading modules from /lib/modules/3.0.76-0.11-default/extra
runmmfs: The /lib/modules/3.0.76-0.11-default/extra/mmfslinux.ko kernel extension does not exist.
runmmfs: Unable to verify kernel/module configuration.
Tue Apr 1 22:02:11 CST 2014 runmmfs: error in loading or unloading the mmfs kernel extension
Tue Apr 1 22:02:11 CST 2014 runmmfs: stopping GPFS
解决方案：重新编译一下gpfs的源码,因为手工卸载gpfs 。
/usr/lpp/mmfs/src/README有详细的编译方法:主要命令方法如下:
#cd /usr/lpp/mmfs/src
#make Autoconfig
#make InstallImages
make InstallImages会在/lib/modules/`uname -r`/extra目录生成3个文件，大功告成.
创建实例
创建实例前:
node02#/opt/ibm/db2/V10.5/instance/db2icrt -cf node01 -cfnet node01
-m node02 -mnet node02 -instance_shared_dir /db2sd_20140401
-tbdev 192.168.18.2 -u db2fenc1 db2inst1
-tbdev 官方解释为:Specifies a shared device path for a device that will act as a tiebreaker in the DB2 pureScale environment to ensure that the integrity of the data is maintained. 通俗的讲就是在member出现故障时，判断哪个member可以恢复服务，穷屌丝们就用网关IP来代替了，只要能 ping 通即可判断为可用 。
此时执行:# db2instance -instance db2inst1 -list可以查看
node01:/opt/ibm/db2/V10.5/instance # mmlscluster
GPFS cluster information
========================
GPFS cluster name: db2cluster_20140401103900.site
GPFS cluster id: 6571095102926235332
GPFS UID domain: db2cluster_20140401103900.site
Remote shell command: /var/db2/db2ssh/db2locssh
Remote file copy command: /var/db2/db2ssh/db2scp
GPFS cluster configuration servers:
-----------------------------------
Primary server: node01.site
Secondary server: node02.site
Node Daemon node name IP address Admin node name Designation
----------------------------------------------------------------------
1 node01.site 192.168.18.201 node01.site quorum-manager
2 node02.site 192.168.18.202 node02.site quorum-manager
曾经出现报错:
错误1、报2632-044、2632-068，此类错误为创建tsa domain时的错误 ， 原因在于虚拟机是拷贝的 ， 不是重新安装的 。
解决方法:#/usr/sbin/rsct/install/bin/recfgct
启动实例
node01:$/home/db2inst1/sqllib/adm/db2start
怎么样,报错了吧，应该是SQL1721N
SQL1721N Starting the DB2 database manager failed because of a problem with a configuration file that is needed by RDMA.受打击吧 。
【linux命令进入db2 linux命令进入桌面】你装完了实例启动不了，没关系，这么高档的玩意怎么能让你这么快启动啊 。
