GPFS添加物理磁盘的过程

GPFS添加物理磁盘的过程

 

1,创建临时文件

[root@sdcmpdb1 ~]# vi /tmp/nsdprofile2

 

emcpoweri:::dataAndMetadata::

emcpowerj:::dataAndMetadata::

emcpowerk:::dataAndMetadata::

emcpowerl:::dataAndMetadata::

emcpowerm:::dataAndMetadata::

 

2,生成nsd磁盘

mmcrnsd -F /tmp/nsdprofile2

 

[root@sdcmpdb1 ~]# mmcrnsd -F /tmp/nsdprofile2

mmcrnsd: Processing disk emcpoweri

mmcrnsd: Processing disk emcpowerj

mmcrnsd: Processing disk emcpowerk

mmcrnsd: Processing disk emcpowerl

mmcrnsd: Processing disk emcpowerm

mmcrnsd: Propagating the cluster configuration data to all

  affected nodes.  This is an asynchronous process.

  

3,查看目前的nsd盘

[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文件系统中，注意对应的gpfs_lv是上面步骤查到的文件系统名

[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 KB

Extending Allocation Map

Checking Allocation Map for storage pool system

Completed adding disks to file system gpfs_lv.
