The resource manager of heartbeat haresource mode is a shell script,
named ResourceManager.
It has a function acquireresourcegroup(),
which loops through all resources you defined,
runs "status" on them, and if that does not indicate they are running,
it runs "start" on them.
for j in "$@"
do
if
we_own_resource "$j" || doscript "$j" start
then
: $j start succeeded
else
...
There is no log message coming from "we_own_resource".
We could easily add one, of course, if you like that better.
So all is well, only the "nfs" thingy seemed to have been up "unexpectedly".
May I ask why you chose to use heartbeat haresource mode
instead of RHCS or Pacemaker, or any other potential candidate for the job?
Just curious here. I'm trying to figure out how common it is nowadays
to do new haresources deployments with new projects.
