Hello all, My current setup si similar with one described here: http://sources.redhat.com/cluster/gnbd/gnbd_usage.txt excepting the fact that i'm having 3 clients and 3 gnbd servers (exporting block devices using gnbd). our gnbd servers have the following IPs: 192.168.113.6 and 192.168.113.7 our gnbd clients have the following IPs: 192.168.113.3 and 192.168.113.4 and 192.168.113.5 On our management machine (other then above gnbd clients and servers) is running: [root@rhclm ~]# rpm -q luci luci-0.12.0-7.el5.centos.3 [root@rhclm ~]# On our gnbd clients is running: [root@rs1 ~]# rpm -q ricci ricci-0.12.0-7.el5.centos.3 [root@rs1 ~]# Now, i'm trying to do the following operations using conga: Cluster -> Shared Fence Devices -> Add Fence Device added successfully: Fence Type: GNBD Name: gnbd_from_shds Servers: 192.168.113.6 192.168.113.7 This will add in our cluster.conf: <fencedevices> <fencedevice agent="fence_gnbd" name="gnbd_from_shds" servers="192.168.113.6 192.168.113.7"/> </fencedevices> Let's try to use it: Cluster -> Nodes hit on 192.168.113.3 and select option "Manage Fencing for this Node" -> "Main Fencing Method" -> "Add a fence device to this level" -> select gnbd_from_shds -> and hit "Update main fence properties" Is not working, all the time i'm getting a javascript window error saying the following: [snip] The following errors were found: An unknown device type was given: "gnbd." ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ [end snip] You see, is a dot after "gnbd" which i suppose it causing that error. How can be fixed this error? Now, I edited manually our cluster.conf as following: <clusternode name="192.168.113.3" nodeid="3" votes="1"> <fence> <method name="1"> <device name="gnbd_from_shds" nodename="192.168.113.3"/> </method> </fence> </clusternode> First Question: In docs, i cannot find any explanation about name="value" in <method> tag. As you see, value is "1": <method name="1">. Is this value valid only inside of <clusternode> section or has global semnification in cluster.conf? Can i name it for example "one" or "first_fence_method_for_this_node"? and run: [root@rs1 ~]# ccs_tool update /etc/cluster/cluster.conf Config file updated from version 28 to 29 Update complete. [root@rs1 ~]# Now, i can see using conga in "Shared Fence Devices" section: Shared Fence Devices for Cluster: httpcluster Agent type: Global Network Block Device Name: gnbd_from_shds Nodes using this device for fencing: 192.168.113.3 but, if i'm hitting 192.168.113.3 link, i'll get other error: Site error This site encountered an error trying to fulfill your request. The errors were: Error Type KeyError Error Value 'fence-instance-form-gnbd' Request made at 2008/08/18 12:42:45.164 GMT+3 Any ideas how to fix it? Is my mistake or is a bug in conga? Second Question: Is correct to add and use for the rest of our client nodes below sintax? For: 192.168.113.4 and 192.168.113.5 client nodes: <clusternode name="192.168.113.4" nodeid="2" votes="1"> <fence> <method name="1"> <device name="gnbd_from_shds" nodename="192.168.113.4"/> </method> </fence> </clusternode> and <clusternode name="192.168.113.5" nodeid="1" votes="1"> <fence> <method name="1"> <device name="gnbd_from_shds" nodename="192.168.113.5"/> </method> </fence> </clusternode> For conformity, i am posting below my present cluster.conf file: <?xml version="1.0"?> <cluster alias="httpcluster" config_version="29" name="httpcluster"> <fence_daemon clean_start="0" post_fail_delay="0" post_join_delay="3"/> <clusternodes> <clusternode name="192.168.113.5" nodeid="1" votes="1"> <fence/> </clusternode> <clusternode name="192.168.113.4" nodeid="2" votes="1"> <fence/> </clusternode> <clusternode name="192.168.113.3" nodeid="3" votes="1"> <fence> <method name="1"> <device name="gnbd_from_shds" nodename="192.168.113.3"/> </method> </fence> </clusternode> <clusternode name="192.168.113.6" nodeid="4" votes="1"> <fence/> </clusternode> <clusternode name="192.168.113.7" nodeid="5" votes="1"> <fence/> </clusternode> </clusternodes> <cman/> <fencedevices> <fencedevice agent="fence_gnbd" name="gnbd_from_shds" servers="192.168.113.6 192.168.113.7"/> </fencedevices> <rm> <failoverdomains/> <resources/> </rm> </cluster> Regards, Alx -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
