Dear Rajat,

According to Red Hat GFS, journals are equal to number of nodes in cluster, and according to my understanding it cant be increased later on if i want to add more nodes in cluster, am i right ?

you set it to 3, 2 for cluster nodes and 1 for quorum ? kindly let me know if  i am wrong.

Thanks,
Muhammad Ammad Shah

Dear Rajat,

HI,

I have configured two node cluster and its working fine for SAN (ext3 file system). after this i configured GFS using following.

root# pvcreate  /dev/sdb

root#vgcreate -c y vg1_gfs /dev/sdc1

root#lvcreate -n db_store -l 100%FREE vg1_gfs

root#/etc/init.d/clvmd start

 Started on both nodes.

root#mkfs -t gfs2 -p lock_dlm -t db_clust:db_store -j 4 /dev/vg1_gfs/db_store

root# service gfs start

root#chkconfig --level 345 clvmd on 

root#chkconfig --level 345 gfs on

----------------

the problem is, as i changed File system (ex3) resource to GFS Resource.

nodes are rebooting..

there is nothing in /var/log/messages. but when i checked console of the node there was some message related to GFS. 

DLM id:0 ...

so i removed GFS and switched back to File system(ext3) resource. 

can i install oracle on  Resource File system(ext3) ?

or how to troubleshoot GFS reboot..

need help,		

Thanks,
Muhammad Ammad Shah
