请教关于GPFS版本升级的问题

henghengxj

如果现在给一套GPFS进行版本升级的话  应该怎样进行呢？\r\n是umount所有节点后 直接打patch？还是需要把老版本的卸载掉？\r\n如果直接打patch的话 会破坏现有数据么？

我老婆黑社会

是大版本,还是小补丁?说详细点

两种情况都想问下\r\n现在具体环境配置还没拿到手 所以想咨询的周全点 多谢

大版本的刚才我倒是找到了点资料  \r\n好象是 smsupdatenode -ai gpfs*1.3.0-0* rsct*2.3.0.10-0*\r\n不知道是不是这个？\r\n\r\n另外 小版本升级呢？该怎么做呢

henghengxj

smsupdatenode\r\n这个命令是gpfs自己的还是linux的？\r\nredhat的有这个命令么？\r\n\r\n怎么搜到的都是在IBM的系统下

henghengxj

还想了解下  对于应用中的gpfs  这种升级 会对当前配置 有影响么 如果升级时候严格按步骤

LZ不习惯查IBM官网或者红皮书.....\r\nhttp://publib.boulder.ibm.com/in ... er.doc/library.html\r\n自己去看吧:\r\nMigrating to GPFS 3.2 from GPFS 3.1\r\n\r\nGPFS V3.2.1 Concepts, Planning, and Installation Guide\r\nGA76-0413-02 \r\n\r\n \r\n \r\n\r\nGPFS™ 3.2 supports node-at-a-time migration if the previous nodes in the cluster are running GPFS 3.1. GPFS 3.1 nodes can coexist and interoperate with nodes running GPFS 3.2. However, some new functions (such as creating a GPFS file system to be mountable on Microsoft® Windows&reg, that depend on format changes will not be available until all nodes have been migrated.\r\n\r\nTo migrate a cluster to GPFS 3.2 from GPFS 3.1, perform these steps: \r\nStop all user activity in the file systems on the designated node. \r\nCleanly unmount the mounted GPFS file system. Do not use force unmount on the designated node. \r\nFollow any local administrative backup procedures to ensure protection of your file system data in the event of a failure. \r\nStop GPFS on the node to be migrated in the cluster, for example: \r\nmmshutdown -N k164n04Copy the installation images and install the new code on each node in the cluster as described in Installing GPFS on Linux nodes or Installing GPFS on AIX nodes. \r\nStart GPFS on the designated node in the new cluster, for example, issue: \r\nmmstartup -N k164n04Mount the file systems if this is not done automatically when the GPFS daemon starts.
