Hi,
I observed below error message when I upgraded drbd to drbd-8.3.0 in
heartbeat 2.1.4 cluster on 2.6.18-8.el5xen.

Thanks for the patch. But do all supported drbd versions have the
role command?
Thanks,
Dejan
No, only 8.3 has the change. 8.2 supports the old "state" argument, but
prints a warning message out, and this warning message upsets the drbd OCF
scripts parting of drbdadm's output.
drbdadm doesn't support a --version argument, but it does support a "status"
command, which has version info in it. However, I am not sure if "drbdadm
status"
is guaranteed to not block or not, so I didn't want to have the OCF script
depend
on it.
So, I see three alternatives: add a new script "drbdadm8.3". Add an extra
parameter
saying "use role instead of status". Or call "drbdadm status" to dynamically
detect
our version.
Do you see other choices? Do you have a preference for a particular
alternative?
I'm willing to code and test the patch if we can decide what we want.
Neil
