but going back to the initial question.
if you were to compare heartbeat 1.x vs heartbeat 2.x with a V1
config, are there any problems that would show up?
if you just want to have a haresources based cluster, then there is
practically no difference at all between the two versions.
the fact that this can't take advantage of other 2.x features is not
a useful answer.
as for why someone would want to do this, it's much less risky to
upgrade a software package if you don't have to also change the
config drasticly at the same time (especially if the config change
would require training a significant group of people)
In addition, if a person doesn't need the new features of 2.x, but
wants to be running a version that gets patches,
thats a red herring i'm afraid - the v1 resource manager has barely
been touched at all in the last 2-3 years - so it's very unlikely that
there are any patches that are relevant to you
this is a useful option.

I have a basic 2 node cluster, and just tried the conversion you

hb_gui has a seg fault when starting up. This doesn't seem to work

I notice you need a graphical interface (xwindows) to use either
of these
tools.
is there a way to do this WITHOUT the graphics, like a plain
command-line
version?
hb_gui/hbclient does me no good.

Hi eyeryone,
I do have Heartbeat V2 installed and wanted (because I have V2 so
configure it with V2-tools) ("crm yes")). But it's much harder to
understand the V2-configuration with its cib.xml and all the
concepts.
So are there any disadvantages when using the V1-configuration
with a
Heartbeat V2?
Hi,
you could use this script to convert V1 to V2 style.
# /usr/lib/heartbeat/haresources2cib.py /etc/ha.d/haresources
This script will create V2 config file /var/lib/heartbeat/crm/
cib.xml
(Then you could use hbclient or hb_gui to modified cluster
settings).
Good luck!
We only want to make some services high-available (FTP etc.) in a
cluster with two nodes and mirror some filesystems to the active
node
via DRBD.
Tanks for answers :)
