[OSR-users] Some informations

[Stefano E. <ste...@so...>]

Hi Marc,

I created a two-node OCFS2 cluster and now I need some information.
- To add a new IP address to the cluster, what should I do ?
   I have tried to change the file cluster.conf but it seems that the  
change will not be read.
   I tried also the procedure for updating the version of the file  
cluster.conf but nothing.

- What changes need to update the image file initrd ?

- I saw that there were some updates in packages rpm, I can do update  
my servers with the new packages,
   or it might create problems ?


Thanks

You just need to update the cluster.conf with the new node and <com_info> 
section.
Then build a new initrd:
mkinitrd ..
then create a new ocfscluster.conf:
com-queryclusterconf convert ocfs2 > /etc/ocfs2/cluster.conf
Do whatever ocfs2 needs to do when nodescount have been updated.

Then create the cdsl infrastructure:
cp -a /cluster/cdsl/default /cluster/cdsl/<newnodeid>
Adapt the hostdependent files (ip address ..)

Boot the third node.

It shouldn't ;-)
These are preview rpms.
So you might think about stabilizing your current approach and then update to 
new versions.
