Re: [Linux-cluster] GFS continue to reboot nodes




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,

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
