Hi,
sigh. Why does everyone reinvent the wheel?
There was a pretty good cluster-software out there (commercial)
who said anything about re-inventing?
"re-implementing" sure, but there aren't exactly many FOSS cluster
projects to be borrowing code from.
granted not everything about our implementations are always perfect^,
but there's no need to get all preachy about it.
^ you rightly point out the fail-count code, to which I'd reply that
we've been planning to do something about it for some time but lack
the resources.
which
used the following set of variables for every cluster resource (to be
exact: for every resource type):
- general action timeout
- CI confidence-interval (if online after x seconds clear
failure-counter), CI > (MI + MT) * TL + MI + 10
- first start monitor wait time (in number MIs)
- MT monitor timeout
- number of local restart tries
- number of monitor timeouts before failure
- MI monitor interval
- offline monitor inverval
- offline timeout
- online timeout
- critical (yes/no: if yes, a resource fault will trigger a
resource-group fault)
- TL tolerance limit (how many monitor intervals with result "down"
will
it take to declare resource faulted)
This is IMHO the most important subset of attributes which every
resource should have (the mentioned software has some more - but I
don't
think these are that important).
This would replace some of the complicated resource-dependency-rules
that are neccessary within heartbeat to emulate the resulting
behaviour.
So if you start with timing in lrm - please think about the above.
Kind regards,
Nils

Hello,
I use Linux HA to monitor some services on a dial in machine. A so
called single node lcuster. For example sometimes my dial-in
connection or openvpn connection, or IPv6 connectivity does
not come.
Is there a way to tell Linux-HA to retry a failed resource after a
certain amount of time again?
not yet but soon
only in the last few days has the lrmd started exposing the
timing data required in order to do this
