Hi all,
I'm just wondering what the best way is to
let an admin know that the cluster (rest of
a cluster) has stonithed some other nodes?
What is the recommended way?
(The fact that the machine rebooted or is
halted is not the problem. I want to know
that stonithing was done)
Best regards

Personally, I have a little monitoring script I wrote that watches the
cluster resources, local hardware (via the IPMI BMC), UPSes and
what-not. It loop every 30 seconds and sends an email if/when anything
of note changes. A node being fenced certainly raises a flag and emails
go out.
My script is principally for cman + rgmanager, but it should be easy to
craft your own, too. I just read in the current state of things, compare
against the values in the last scan, decide whether to send an email or
not, copy the just-read values over to the last-scan values and delete
the "new" values and go back to sleep for 30 seconds.
