Sun Cluster 系统管理指南（适用于 Solaris OS）

Procedure如何验证基本群集配置

cluster(1CL) 命令使用 check 命令验证全局群集正常工作所需的基本配置。如果所有检查均未失败，cluster check 将返回到 shell 提示符。如果某项检查失败，cluster check 将在指定的输出目录或默认输出目录中生成报告。如果对多个节点运行 cluster check，cluster check 将分别针对每个节点生成一个报告并针对多个节点的检查生成一个报告。也可使用 cluster list-checks 命令显示所有可用群集检查的列表。

可在详细模式下运行带有 -v 标志的 cluster check 命令，以显示进度信息。

注 –

在执行可能导致设备、卷管理组件或 Sun Cluster 的配置发生更改的管理过程之后，应运行 cluster check。

在全局群集投票节点上运行 clzonecluster(1CL) 命令时，将运行一组检查，以验证区域群集正常工作所需的配置。如果所有检查都通过，clzonecluster verify 将返回到 shell 提示符，您可以放心地安装该区域群集。如果某项检查失败，则 clzonecluster verify 将报告检验失败的全局群集节点。如果对多个节点运行 clzonecluster verify，将针对每个节点和多个节点的检查分别生成一个报告。不允许在区域群集内部运行 verify 子命令。

  1. 成为全局群集的活动成员节点上的超级用户。从全局群集的节点执行此过程中的所有步骤。


    phys-schost# su

  2. 检验群集配置。

    • 检验全局群集的配置。


      phys-schost# cluster check

    • 检验区域群集的配置以了解是否可以安装区域群集。


      phys-schost# clzonecluster verify zoneclustername
示例 1–8 检查全局群集配置并且所有检查均通过

以下示例显示了针对节点 phys-schost-1 和 phys-schost-2 在详细模式下运行的 cluster check，其中节点通过了所有检查。


phys-schost# cluster check -v -h phys-schost-1,  
     phys-schost-2

cluster check: Requesting explorer data and node report from phys-schost-1.
cluster check: Requesting explorer data and node report from phys-schost-2.
cluster check: phys-schost-1: Explorer finished.
cluster check: phys-schost-1: Starting single-node checks.
cluster check: phys-schost-1: Single-node checks finished.
cluster check: phys-schost-2: Explorer finished.
cluster check: phys-schost-2: Starting single-node checks.
cluster check: phys-schost-2: Single-node checks finished.
cluster check: Starting multi-node checks.
cluster check: Multi-node checks finished
#
示例 1–9 检查全局群集配置并且某项检查未通过

以下示例显示，群集 suncluster 中的节点 phys-schost-2 缺少挂载点 /global/phys-schost-1。将在输出目录 /var/cluster/logs/cluster_check/<timestamp> 中创建报告。


phys-schost# cluster check -v -h phys-schost-1, 
phys-schost-2 -o
     /var/cluster/logs/cluster_check/Dec5/

cluster check: Requesting explorer data and node report from phys-schost-1.
cluster check: Requesting explorer data and node report from phys-schost-2.
cluster check: phys-schost-1: Explorer finished.
cluster check: phys-schost-1: Starting single-node checks.
cluster check: phys-schost-1: Single-node checks finished.
cluster check: phys-schost-2: Explorer finished.
cluster check: phys-schost-2: Starting single-node checks.
cluster check: phys-schost-2: Single-node checks finished.
cluster check: Starting multi-node checks.
cluster check: Multi-node checks finished.
cluster check: One or more checks failed.
cluster check: The greatest severity of all check failures was 3 (HIGH).
cluster check: Reports are in /var/cluster/logs/cluster_check/<Dec5>.

CHECK ID : 3065
SEVERITY : HIGH
FAILURE  : Global filesystem /etc/vfstab entries are not consistent across 
all Sun Cluster 3.x nodes.
ANALYSIS : The global filesystem /etc/vfstab entries are not consistent across 
all nodes in this cluster.
Analysis indicates:
FileSystem '/global/phys-schost-1' is on 'phys-schost-1' but missing from 'phys-schost-2'.
RECOMMEND: Ensure each node has the correct /etc/vfstab entry for the 
filesystem(s) in question.
