ipmi fence問題請教大家
內核：2.6.18-194.el5
OS：Red Hat Enterprise Linux Server release 5.5 (Tikanga)
2台IBM x3650 m2做RHCS，用x3650 m2伺服器的ipmi做fence設備
網路設置：
節點1：
public IP 10.72.86.121
private IP 10.1.1.1
ipmi IP 10.72.86.126
節點2：
public IP 10.72.86.122
private IP 10.1.1.2
ipmi IP 10.72.86.127
心跳private IP網口用直連網線連接起來，public IP網口和ipmiIP網口接到同一個交換機
現象1：在節點1上用fence_ipmilan 10.72.86.127命令可以fence節點2,讓節點2重啟了:
# fence_ipmilan -a 10.72.86.127
Rebooting machine @ IPMI:10.72.86.127...Done
但是messages日誌會報如下錯誤信息：
Jun 28 19:47:17 elndb1 fenced: agent "fence_ipmilan" reports: Rebooting machine @ IPMI:10.72.86.127...Failed
Jun 28 19:47:17 elndb1 fenced: fence "elndb2.eln.com" failed
現象2：在節點1上用fence_node elndb2.eln.com命令fence節點2失敗：
# fence_node elndb2.eln.com
agent "fence_ipmilan" reports: Rebooting machine @ IPMI:10.72.86.127...Failed
messages日誌報如下錯誤信息：
Jun 28 20:43:11 elndb1 fence_node: agent "fence_ipmilan" reports: Rebooting machine @ IPMI:10.72.86.127...Failed
Jun 28 20:43:11 elndb1 fence_node: Fence of "elndb2.eln.com" was unsuccessful
cluster.conf文件配置如下：
<?xml version="1.0"?>

<service autostart="0" domain="elndbdomain" name="elndb_svc" recovery="relocate">
<ip ref="10.72.86.130"/>
</service>
</rm>
</cluster>
從messages日誌看到的信息非常有限，請問一下大家該如何處理？
《解決方案》
該問題屬於你的USERID的許可權不夠，所以fence失敗。
《解決方案》
還有一個可能是：
<fencedevice agent="fence_ipmilan" auth="none" ipaddr="10.72.86.127" login="USERID" name="ipmi2" passwd="PASSW0RD"/>
中的auth="none"應該刪掉，存在這個會有問題。另外：你的用戶和密碼是系統默認的特權用戶應該是可以的
