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.
mmadddisk: Propagating the cluster configuration data to all
affected nodes. This is an asynchronous process.
