Hi Sambit, I looked into the quorum server using command "clquorumserver show +" , it showed me the old services that quorum server did server before this setup, so I reinstall my host and setup the quorum server again. From the document that I got from http://opensolaris.org/os/community/ha-clusters/ohac/Documentation/OHACdocs/ , and from the restriction, Veritas Volume Manager is not supported in OpenSolaris HA Cluster. So, I wonder if we need to use metaset to setup diskset to manage the disk or what I have from the doc is enough?
Thanks, Janey -----Original Message----- From: Sambit.Nayak at Sun.COM [mailto:sambit.na...@sun.com] Sent: Wednesday, September 09, 2009 1:53 AM To: Le, Janey Cc: ha-clusters-discuss at opensolaris.org Subject: Re: [ha-clusters-discuss] Host panic - OpenSolaris SunCluster Hi Janey, The error message : > WARNING: CMM: Reading reservation keys from quorum device Auron failed with error 2. means that the node xCid failed to read the quorum keys from the quorum server host Auron. It is possible that the node xCid could not contact the quorum server host Auron at that specific time, when the reconfiguration was in progress due to reboot of xCloud. Also please look in the syslog messages on xCid, for any failure messages related to the quorum server. Is the problem happening everytime you reboot xCloud, after both nodes are successfully online in the cluster? Things that can be done to debug -------------------------------------------- More information about this failure will be available in the cluster kernel trace buffers. If you can obtain the kernel dumps of the cluster nodes at the time of this problem, then we can look into them to debug the problem more. If you are not able to provide the dumps, then please do : > *cmm_dbg_buf/s > *(cmm_dbg_buf+8)+1/s at the kmdb prompt resulting from the panic (or on the saved crash dump), and provide that output. Please also save the /var/adm/messages of both nodes. Each quorum server daemon (on a quorum server host) has an associated directory where it stores some files. By default, /var/scqsd is the directory used by a quorum server daemon. If you have changed the default directory while configuring the quorum server, then please look in it instead. There will be files named ".scqsd_dbg_buf*" in such a directory. Please provide those files as well; they will tell us what's happening on the quorum server host Auron. If you execute "clquorum status" command on a cluster node, then it will tell if the local node can access the quorum server at the time of this command execution or not. If access is possible and the node's keys are present, the quorum server is marked online; else it is marked offline. So if you execute this command on both cluster nodes before doing the experiment of rebooting xCloud, then that will tell whether any node was having problems accessing the quorum server. Please run that command on both nodes, and capture the output, before rebooting xCloud. Similarly, the "clquorumserver show +" on the quorum server host will tell what cluster it is serving, and what keys are present on the quorum server, which cluster node is the owner of the quorum server, etc. Please capture its output before rebooting xCloud, and after xCid panics as a result of rebooting xCloud. ************ Just as a confirmation, the cluster is running Open HA Cluster 2009.06, and you are using the quorum server packages available with Open HA Cluster 2009.06, right?
