Small reminder as I always tend to forget these :
Dump the CRM cib db :
cibadmin -Q > cib.backup.xml
Modify a resource , dump the cib, modify the xml for the resources and then import using cibadmin -M
cibadmin -V -M -o resources -x modified_resources.xml
Add a resource , create the xml for the resource and them use -C
cibadmin -V -C -o resources -x new_resource.xml
Move resource from one location to another, -f to force it …
crm_resource -M -r resource -H host
crm_resource -M -r resource -H host -f
I have recently built a DRBD + Linux HA NFS cluster , part of the structure was to create a drbd disk resource and mount it on /var/lib/nfs. This allows to switch nfs over to the secondary node without getting “stale nfs handle” errors. Heartbeat was having a hardtime doing a clean umount of the file system and ended up rebooting the machine.
Apr 20 06:47:07 fs Filesystem[9823]: [9887]: INFO: No processes on /var/lib/nfs were signalled
Apr 20 06:47:08 fs Filesystem[9823]: [9890]: ERROR: Couldn’t unmount /var/lib/nfs; trying cleanup with SIGKILL
After some poking around the systems It looked like nfs was not showtdown cleanly. looking into the rc script i changed the signal from 2 to 9
From :
stop)
# Stop daemons.
echo -n $”Shutting down NFS mountd: ”
killproc rpc.mountd
echo
echo -n $”Shutting down NFS daemon: ”
killproc nfsd -2
echo
To :
stop)
# Stop daemons.
echo -n $”Shutting down NFS mountd: ”
killproc rpc.mountd
echo
echo -n $”Shutting down NFS daemon: ”
killproc nfsd -9
echo
and now, all is well 
Apr 20 06:52:49 fs Filesystem[8696]: [8754]: INFO: unmounted /var/lib/nfs successfully
searching the web shows this is a somewhat known issue
To add an ip resource who’s a member of group “ip_group” create an xml file :
import the resource using :
cibadmin -V -M -o resources -x file.xml
( note you are using -M to modify the existing group … )
delete the resource :
cibadmin -V -D -o resources -X’
