结点安装完成后需配置共享存储设备,共享存储设备多为SCSI设备或光纤设备,请按照相关的硬件厂商文档进行安装。硬件正常安装后需要对共享存储设备进行分区,共享存储设备用于存放服务所需使用的数据。
在对共享存储进行分区时需要首先分两个10M大小的分区做为裸设备供高可用集群使用,另外建议每服务的数据使用一个分区来存放数据,具体分区如下所示。该配置只需要在一台成员服务器上执行。
[root@node1 root]# fdisk /dev/sdb

Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

在上述示例中我们共分了四个分区,其中sdb1、sdb2为两个10M的分区需配置为裸设备,sdb3、sdb4分别为两个1G的分区,分别供NFS及SAMBA服务存放数据使用。分区完成后重启计算机并在每台服务器上执行fdisk –l以确定各结点能够正确识别磁盘及其分区设备。 (责任编辑:IT)
