Hi,
I filed the bug.
http://developerbugs.linux-foundation.org/show_bug.cgi?id=2120
I could reproduce this behavior with a simple primitive resource.
There are two problems.
(1) the following syntax doesn't work well
crm(live)resource# failcount <rsc> delete <node>
(2) When using "set" switch, _all_ node's fail count would be set as 0.
crm(live)resource# failcount <rsc> set <node> 0
Thanks,
Junko
