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'.

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

问题解决了么？
我在V10.1 GA里安装的时候，也碰到这个问题
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
DB2安装的时候，使用了db2_install的命令。但注意到了这个命令已经deprecated
DBI1324W Support of the db2_install command is deprecated. For more information, see the DB2 Information Center.
改用db2setup，并在安装的时候，创建instance，之后instance创建成功。
另外，我不是使用ISCSI 共享存储，而是直接使用VMware的虚拟磁盘，进行共享，在VMware的VMX文件中，包含如下参数
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
scsix.sharedBus = "virtual"
scsix:x.shared = "TRUE"
scsix:x.mode = "independent-persistent"
在VMware Workstation 10，和VMware ESX 4.1中，均成功创建三个节点的pureScale cluster。在VWare Workstation 10是直接安装的DB2 10.1 GA，在ESX 4.1上的cluster是先装V9.7，然后转换到V9.8，最后升级到10.1 GA的。在从V9.8升级到10.1的时候，db2iupgrade同样报了usePersistentReserve的问题，后使用db2iupgrade_local 在每个节点上单独进行升级。从V9.8升级到10.1后，需要注意/var/ct/cfg/netmon.cf的配置。
