GPFS添加物理磁碟的過程

GPFS添加物理磁碟的過程 1,建立臨時檔案[root@sdcmpdb1 ~]# vi /tmp/nsdprofile2 emcpoweri:::dataAndMetadata::emcpowerj:::dataAndMetadata::emcpowerk:::dataAndMetadata::emcpowerl:::dataAndMetadata::emcpowerm:::dataAndMetadata:: 2,產生nsd磁碟mmcrnsd -F /tmp/nsdprofile2 [root@sdcmpdb1 ~]# mmcrnsd -F /tmp/nsdprofile2mmcrnsd: Processing disk emcpowerimmcrnsd: Processing disk emcpowerjmmcrnsd: Processing disk emcpowerkmmcrnsd: Processing disk emcpowerlmmcrnsd: Processing disk emcpowermmmcrnsd: Propagating the cluster configuration data to all  affected nodes.  This is an asynchronous process.  3,查看目前的nsd盤[root@sdcmpdb1 ~]# mmlsnsd  File system   Disk name    NSD servers                                    --------------------------------------------------------------------------- gpfs_lv       gpfs1nsd     (directly attached)       gpfs_lv       gpfs2nsd     (directly attached)       gpfs_lv       gpfs3nsd     (directly attached)       (free disk)   gpfs4nsd     (directly attached)       (free disk)   gpfs5nsd     (directly attached)       (free disk)   gpfs6nsd     (directly attached)       (free disk)   gpfs7nsd     (directly attached)       (free disk)   gpfs8nsd     (directly attached)  4,添加nsd到gpfs檔案系統中，注意對應的gpfs_lv是上面步驟查到的檔案系統名[root@sdcmpdb1 ~]# mmadddisk gpfs_lv -F /tmp/nsdprofile2 The following disks of gpfs_lv will be formatted on node sdcmpdb1:    gpfs4nsd: size 146801280 KB    gpfs5nsd: size 146801280 KB    gpfs6nsd: size 146801280 KB    gpfs7nsd: size 146801280 KB    gpfs8nsd: size 146801280 KBExtending Allocation MapChecking Allocation Map for storage pool systemCompleted adding disks to file system gpfs_lv.mmadddisk: Propagating the cluster configuration data to all  affected nodes.  This is an asynchronous process.
