[Pacemaker] Filesystem RA would cause "stop timeout" if it mounts shared storage

Hi, I found the following event; 1) Mount shared storage drive using Filesystem RA. 2) Unlink the Fibre Channel, so RA can not access the shared storage for now. 3) RA detects the monitor failure and calls Filesystem_stop(). 4) Filesystem_stop() goes into a timeout error. The current Filesystem

Re: [Pacemaker] OCF Resource agent monitor activity failed due to temporary error

Neither the cluster manager nor the RA can know that the error is temporary. You can only know that with the benefit of hindsight. So what you're asking for is that the cluster ignores the first N errors... which doesn't sound very "HA". The better approach is write the RA in such a way that it do

That's a very interesting idea. Since I'm generating the configuration from a script, that would be easy to add. Also, I could have a variety of different - even overlapping - pseudo-groups implemented in this way. On 04/19/2012 11:48 AM, David Vossel wrote: - Original Message -
