[Linux-cluster] drbd+GFS HA cluster

[anugunj anuj singh]

Hi,
I installed drbd-8.0.3 on RHEL4, my drbd.conf

global { usage-count yes; }
       common { syncer { rate 10M; } } 
       resource r0 { 
            protocol C; 
            net { 
                 cram-hmac-alg sha1; 
                 shared-secret "anugunj"; 
            } 
            on node0005.anugunj.com { 
                 device    /dev/drbd1; 
                 disk      /dev/hda6; 
                 address   10.1.1.3:7789; 
                 meta-disk  internal; 
            } 
            on node0021.anugunj.com { 
                 device    /dev/drbd1; 
                 disk      /dev/sdb1; 
                 address   10.1.1.11:7789; 
                 meta-disk  internal; 
            } 
       } 
                                                
created drbd-meta data
drbdadm create-md r0
 , and then gfs file system on it. 
I am trying to do mirroring of cluster, using gfs file system ,
currently I have to make one drbd hard disk primary, other secondary,
only then I am able to mount and use, on other system it is not
mounting, i have to make it primary with.
drbdadm primary all.

has anyone tried drbd on gfs, filesystem. Version i am using does
support gfs (according to changelog)
http://svn.drbd.org/drbd/trunk/ChangeLog . Target is for HA of cluster.
while mounting drbd hard disks on both systems simultaneous. 

thanks and regards
