linux - GPFS : mmremote: Unable to determine the local node identity

Question

我有一个 4 节点，gpfs 集群启动并运行，一切都很好，直到上周托管这些 RHEL 设置的服务器出现故障，在服务器启动并重新启动 rhel 节点后，其中一个节点的 IP变了，

在那之后我无法使用该节点，

诸如“mmlscluster”、mmgetstate 之类的简单命令失败并出现此错误:

[root@gpfs3 ~]# mmlscluster mmlscluster: Unable to determine the local node identity. mmlscluster: Command failed. Examine previous error messages to determine cause. [root@gpfs3 ~]# mmstartup mmstartup: Unable to determine the local node identity. mmstartup: Command failed. Examine previous error messages to determine cause.

Mmshutdown 失败并出现不同的错误:

[root@gpfs3 ~]# mmshutdown mmshutdown: Unexpected error from getLocalNodeData: Unknown environmentType . Return code: 1

日志有这个信息:

Mon Feb 15 18:18:34 IST 2016: Node rebooted. Starting mmautoload... mmautoload: Unable to determine the local node identity. Mon Feb 15 18:18:34 IST 2016 mmautoload: GPFS is waiting for daemon network mmautoload: Unable to determine the local node identity.

我试过换IP，还是一样的错误:

[root@gpfs1 ~]# mmchnode -N gpfs3 --admin-interface=xx.xx.xx.xx Mon Feb 15 20:00:05 IST 2016: mmchnode: Processing node gpfs3 mmremote: Unable to determine the local node identity. mmremote: Command failed. Examine previous error messages to determine cause. mmremote: Unable to determine the local node identity. mmremote: Command failed. Examine previous error messages to determine cause. mmchnode: Unexpected error from checkExistingClusterNode gpfs3. Return code: 0 mmchnode: Command failed. Examine previous error messages to determine cause.

有人可以帮我解决这个问题吗？

最简单的修复可能是从集群中删除节点 (mmdelnode)，然后将其添加回 (mmaddnode)。您可能需要 mmdelnode -f。

如果删除并重新添加节点不是一个选项，请尝试给 IBM 支持人员打电话。
