recurso de configuração do pacemaker para nginx

estou tentando construir um cluster por duas vm usando o virtualbox, sigo este tutorial http://www.tokiwinter.com/clustering-with-drbd-corosync-and-pacemaker/

e digite o comando conforme abaixo

[root@node1 data]# crm configure primitive nginx_res ocf:heartbeat:nginx params configfile=/etc/nginx/nginx.conf httpd=/usr/sbin/nginx op monitor interval=60s timout=10s op start timeout=40s op stop timeout=60s
   error: unpack_resources:     Resource start-up disabled since no STONITH resources have been defined
   error: unpack_resources:     Either configure some or disable STONITH with the stonith-enabled option
   error: unpack_resources:     NOTE: Clusters with shared data need STONITH to ensure data integrity
Errors found during check: config not valid
ERROR: ocf:heartbeat:nginx: got no meta-data, does this RA exist?
ERROR: ocf:heartbeat:nginx: got no meta-data, does this RA exist?
ERROR: ocf:heartbeat:nginx: no such resource agent
Do you still want to commit (y/n)?

é normal essas mensagens de erro? como posso restaurar depois de pressionar sim? o que o comando vai fazer?
