GPFS添加物理磁盘的过程 -电脑资料

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: Pro

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 systemDisk nameNSD servers

gpfs_lvgpfs1nsd(directly attached)

gpfs_lvgpfs2nsd(directly attached)

gpfs_lvgpfs3nsd(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:
