Earlier I thought RHEL release no. is directly mapped to cluster version and hence I was reading release from /etc/redhat-erlease file and get cluster specific commands to get cluster info. e.g. RHEL 2.1 "/sbin/cluadmin -- cluster status" RHEL 3.0 "/usr/sbin/clustat" But I noticed that RHEL 3.0 could have cluster setup where "/sbin/cluadmin -- cluster status" works. ( Where my code fails :-( ). So now I need to find a way to detect cluster version and use corresponding cluster commands. Rajesh has given a pointer to detect version For RHEL 2.1 and 3.0 run "rpm -qa |grep clumanager" and for rhel4.0 use ccs,cman,fence independent rpms to find the version. ( Rajesh which is the appropriate command to find version for RHEL4.0 ?) m/c 1: # rpm -qa |grep clumanager clumanager-1.0.11-1 # rpm -q redhat-release redhat-release-3AS-13.5.1 # cat /etc/redhat-release Red Hat Enterprise Linux AS release 3 (Taroon Update 5) # ls -l /sbin/cluadmin -rwxr-xr-x 1 root root 533296 Apr 17 2002 /sbin/cluadmin m/c 2: # rpm -qa |grep clumanager clumanager-1.2.3-1 # rpm -q redhat-release redhat-release-3AS-1 # cat /etc/redhat-release Red Hat Enterprise Linux AS release 3 (Taroon) # ls -l /sbin/cluadmin ls: /sbin/cluadmin: No such file or directory # ls -l /usr/sbin/clustat -rwxr-xr-x 1 root root 56128 Oct 6 2003 /usr/sbin/clustat Do I need to consider second bit for cluster release? (e.g 2 in clumanager-1.2.3-1) Thanks friends for your help. Have a nice day ! - Krishna <div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">----- Original Message ---- From: Lon Hohberger <lhh@redhat.com> To: linux clustering <linux-cluster@redhat.com> Sent: Thursday, January 11, 2007 8:35:24 PM Subject: Re: [Linux-cluster] cluster version identification:how? <div>On Thu, 2007-01-11 at 03:34 -0800, krishnamurthi G wrote: > Hi Frieds, > > Is there any ways to find cluster version (if it is !). > Problem: The cluster specific commands/paths/command outputs have been > changed/changing completely from RHEL 2.1 to 2.4 to 2.6. > I am working on a project where I need support for all > version/releases, some how I need to find cluster version if available > so that I can parse accordingly. > Temporary Work around: The cluster config file is unique for different > RHEL releases. > e.g RHEL 2.1 "/etc/cluster.xml" > RHEL 2.4 "/etc/cluster.conf" > RHEL 2.6 "/etc/cluster/cluster.conf" > > Check this config file and identify cluster type. RHEL 2.1: /etc/cluster.conf RHEL3: /etc/cluster.xml RHEL4: /etc/cluster/cluster.conf RHEL5: /etc/cluster/cluster.conf Why not just do 'rpm -q redhat-release'? I'm curious; why does the cluster version matter: are you manipulating cluster.[xml|conf] directly? If so, you'll need to do a few extra things. -- Lon -- Linux-cluster mailing list Linux-cluster@redhat.com <a target="_blank" href="https://www.redhat.com/mailman/listinfo/linux-cluster">https://www.redhat.com/mailman/listinfo/linux-cluster</a> </div></div> </div></div> <hr size=1>Check out <a href="http://us.rd.yahoo.com/evt=43257/*http://advision.webevents.yahoo.com/mailbeta">the all-new Yahoo!
