RHCS: cman: can't open cluster socket: Device or resource busy failed
添加NODE時啟動cman時會出現上面的情況，但重新將其它伺服器
重新啟動一下就又可以了。
=======================================
難道新添一個node需要重新啟動其它的所有伺服器嗎？估計沒有這樣的。
倒底是怎麼樣添加node呢？<?xml version="1.0"?>

《解決方案》
每改變一次伺服器配置，我必須把所有的伺服器的關於RHCS重新啟動一次才行，不然這個問題必定會出來。
還是沒有找到問題的解決方法~

請問你是哪個版本的平台 以及RHCS 版本 以便確認問題
《解決方案》
Redhat 4 update 7的版.....
RHCS具體的版本不明白你說的什麼意思?
ftp://ftp.redhat.com/pub/redhat/linux/updates/enterprise/4AS/en/RHCS/SRPMS/
難道不是每個OS系統都會對應不同的版本么.
ccs 1.0.7
fence
dlm-kernel-2.6.9-54.11
dlm-1.0.7-1
cman-1.0.17
fence-1.32.63
iddev-2.0.0-4
rgmanager-1.9.38-0
GFS-kernel-2.6.9-80
GFS-6.1.18-1
等等.
《解決方案》
更改集群配置，使之生效一般用ccs_tool update /etc/cluster/cluster.conf，操作之前記得改一下配置版本號；之後要使用cman_tool -r後面跟版本號。不用重啟集群服務。

謝謝。都怪自已看文檔不仔細.^0^
The cluster configuration guis take case of propagating changes to cluster.conf to your cluster. The system-config-cluster gui has a big button that says "Send to Cluster". If you're maintaining your cluster.conf file by hand and want to propagate it to the rest of the cluster, do this:
1. Edit /etc/cluster/cluster.conf using the editor of choice.
2. Tell ccs about the change:
ccs_tool update /etc/cluster/cluster.conf
3. Find out what version your cluster.conf file currently is from cman's perspective:
cman_tool status | grep "Config version"
It should come back with something like this:
Config version: 37
4. Tell cman your newer cluster.conf is a newer version:
cman_tool version -r 38
Note: For RHEL5 and similar, cman_tool -r is no longer necessary.
