gpfs增加物理磁盘

当前磁盘大小

[root@controller01 ~]# df -Th
Filesystem          Type      Size  Used Avail Use% Mounted on
/dev/mapper/cl-root xfs       450G   46G  405G  11% /
devtmpfs            devtmpfs   32G     0   32G   0% /dev
tmpfs               tmpfs      32G   39M   32G   1% /dev/shm
tmpfs               tmpfs      32G  1.8G   30G   6% /run

/dev/sda1           xfs      1014M  192M  823M  19% /boot
/dev/mapper/cl-home xfs        56G   33M   56G   1% /home
tmpfs               tmpfs     6.3G     0  6.3G   0% /run/user/0
/dev/fpofs0         gpfs      600G  5.4G  595G   1% /gpfs/fpofs0      

 

 

 

查询当前nsd磁盘情况

[root@controller01 ~]# mmlsnsd

File system Disk name NSD servers
---------------------------------------------------------------------------
fpofs0 nsd1_data controller01,controller02,controller03

 

 

 

新增磁盘文件

[root@controller01 ~]# cat /etc/gpfs/gpfsdisk2
%nsd:nsd=nsd2_data device=/dev/sdd usage=dataAndMetadata servers=controller01,controller02,controller03 failureGroup=102

 

初始化磁盘文件

[root@controller01 ~]# mmcrnsd -F /etc/gpfs/gpfsdisk2
mmcrnsd: Processing disk sdd
mmcrnsd: Propagating the cluster configuration data to all
affected nodes. This is an asynchronous process.

 

 

在来查询一下

[root@controller01 ~]# mmlsnsd

File system Disk name NSD servers
---------------------------------------------------------------------------
fpofs0 nsd1_data controller01,controller02,controller03
(free disk) nsd2_data controller01,controller02,controller03

 

 

增加磁盘到系统文件

root@controller01 ~]# mmadddisk fpofs0 -F /etc/gpfs/gpfsdisk2

The following disks of fpofs0 will be formatted on node controller01:
nsd2_data: size 614400 MB
Extending Allocation Map
Checking Allocation Map for storage pool system
Completed adding disks to file system fpofs0.
mmadddisk: Propagating the cluster configuration data to all
affected nodes. This is an asynchronous process.

 

 

查询nsd

[root@controller01 ~]# mmlsnsd

File system Disk name NSD servers
---------------------------------------------------------------------------
fpofs0 nsd1_data controller01,controller02,controller03
fpofs0 nsd2_data controller01,controller02,controller03

 

扩展后gpfs磁盘大小

[root@controller01 ~]# df -Th

/dev/fpofs0         gpfs      1.2T  5.4G  1.2T   1% /gpfs/fpofs0
