Hello all,

Example of my problem:I build a 2-node cluster (web1 and web2), for a web server ( DRBD + Virtual IP + APACHE service )  
Here web1 is DC, active/master node and start all resources.

# Last change: Thu Jun 21 18:03:33 2012 by root via crm\_attribute on web1 Stack: openais Current DC: web1 - partition with quorum Version: 1.1.6-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 2 Nodes configured, 2 expected votes 5 Resources configured.

Online: [web2 web1]

fs (ocf:💓Filesystem): Started web1  
Resource Group: webname  
virtual-ip (ocf:💓IPaddr2): Started web1  
lampp (lsb:my\_service): Started web1  
Master/Slave Set: ms\_drbd [drbd]  
Masters: [web1]  
Slaves: [web2]  
[/QUOTE]

I have noticed, that when I stop web2 (node which is passive), all resources on web1 are OK.  
When I re-start the web2 server (or cluster openais service), all resources on web1 are restarted ( so no web access during 1sec)

This “ressource restart” is unnecessary …can I prevent it ? It’s not for 1sec, but it’s seems weird for me.

Thanks for future answers.  
Filipo

Hi Filipo,

are the “restarts” probably caused by resource moves from web1 to web2, once web2 goes online?

Hello,

No, all resources stays on web1 (preferred node).  
I can check with “crm\_mon”, before and after: All is on web1 → web2 never used.

I group my “virtual-ip” and my “service\_lampp”, and made web1 my favorite.

Thanks  
Filipo

[SOLVED]

It’s because i started my resources with “primitive foo lsb:bar” and not “primitive foo ocf:heartbeat:bar”.

Thanks

Hi Filipo,

thanks for the feedback - I’d never have guessed that cause!
