互联网服务pureScale安装部署
在虚拟机上搭建purescale出现问题。哪位大哥帮忙看看啊
使用脚本安装的，在1节点安装实例：
./db2icrt -d -cf suse1.mydb.com:suse1.mydb.com -m suse1.mydb.com:suse1.mydb.com -instance_shared_dir /db2fs/ -tbdev 192.168.1.1 -u db2psc db2psc
You need DB2 HA scripts to use SA MP with the DB2 HA feature.
These DB2 HA scripts are located at /usr/sbin/rsct/sapolicies/db2. The
DB2 installer detects whether these DB2 HA scripts need to be installed
or updated.
User response:
No action is required.

ERROR: The shared file system cluster option 'usePersistentReserve' has not been set to the optimal value of 'yes'. See the DB2 Information Center for more details.
There was an internal db2cluster error. Refer to the diagnostic logs (db2diag.log or /tmp/ibm.db2.cluster.*) and the DB2 Information Center for details.
A diagnostic log has been saved to '/tmp/ibm.db2.cluster.qxLGpY'.
ERROR: The existing GPFS cluster, "suse1.mydb.com", does not meet the

Post Install Recommendations
-----------------------------
Required steps:
There were some errors detected during DB2 installation. To collect the information files from the system, run the "db2support -install" command with the proper options before reporting the problem to IBM service. For information regarding the usage of the db2support tool, check the DB2 Information Center.

使用gpfs命令修改：
/usr/lpp/mmfs/bin/mmchconfig usePersistentReserve=yes
suse1:/db2/instance # /usr/lpp/mmfs/bin/mmchconfig usePersistentReserve=yes
Verifying GPFS is stopped on all nodes ...
mmchconfig: Processing disk gpfs1nsd
mmchconfig: Device sdb does not support PR_shared reserve policy.
mmchconfig: Unable to set reserve policy PR_shared on disk gpfs1nsd on node suse1.mydb.com.
mmchconfig: Unable to enable Persistent Reserve on the following disks:
gpfs1nsd
mmchconfig: The usePersistentReserve parameter will remain unchanged.
mmchconfig: Command failed. Examine previous error messages to determine cause.
suse1:/db2/instance #
suse1:/db2/instance #
suse1:/db2/instance #
共享存储时使用虚拟机管理的 我尝试了ISCSI的共享存储 也是修改不了
/mmchconfig usePersistentReserve=yes
安装方式参照：http://www.ibm.com/developerworks/cn/data/library/techarticle/dm-1207maoq/
哪位大侠 能帮忙回答下吗 卡这上面一直解决不了

哪天有时间做个step by step 给大家把，不过涛哥的文档照着做下去也不会有很大问题，感谢涛哥付出的努力！收起

安装完成了，确实需要更改这个/var/ct/cfg/netmon.cf文件才能启动收起

大家知道10.5 purescale 这个文件 /var/ct/cfg/netmon.cf 是怎么配置的吗收起

./db2cluster -cfs -verify -configuration 这个通过不了没有太大的关系，v10.5安装时跟usePersistentReserve=no,我这儿的提示是硬盘不支持。看上去你的gpfs源代码编译没有成功，如果是v9.8的默认是不支持3的内核的，你得修改一下源文件或者操作系统的内核版本骗过检测。一会儿我找一下具体的文件收起

春节后，将环境升级到了DB2 pureScale V10.5 FP1，中间还是碰到了usePersistentReserve的问题，将instance删掉重建解决问题。收起

要使 GPFS 能够更快对故障作出响应，请更新 failureDetectionTime 和 leaseRecoveryWait 参数：
/usr/lpp/mmfs/bin/mmlsconfig
/usr/lpp/mmfs/bin/mmchconfig failureDetectionTime=30
/usr/lpp/mmfs/bin/mmchconfig leaseRecoveryWait=25收起
/usr/lpp/mmfs/bin/mmlsconfig
/usr/lpp/mmfs/bin/mmchconfig failureDetectionTime=30
/usr/lpp/mmfs/bin/mmchconfig leaseRecoveryWait=25收起

OK 等有时间闲下来了 做这个实验 谢谢大家收起
