empty arguments in haresources?

Hi folks,

Maybe a stupid question, but I haven't found it answered
anywhere: How can I provide empty arguments to the "old"
resource scripts via haresources? Something like

Filesystem::/space/data::/nfs4/data::::bind
or
Filesystem::/space/data::/nfs4/data::""::bind

Regards

Harri

Attached is a small patch to make the Filesystem script
of 2.1.4 support

Filesystem::/space/data::/nfs4/data::none::bind

Hope this helps. Regards

Many thanks for the patch, but bind mounts support has been
thoroughly revised at the beginning of 2009. Your version is
obviously older. Though I'm not sure if that would help for
haresources: v1 configuration is currently unmaintained.

Thanks,

Dejan

I am using heartbeat 2.1.4 (taken from Debian unstable and
backported to Lenny). 2.99 is not an option right now, even
though it seems it appeared on Debian experimental.

Is there some documentation about how the bind mounts should
be done using the v2 configuration?

Please note that the patch is for the v2 Filesystem script.
Supporting FSTYPE=none as an alias for FSTYPE="" might be a
reasonable extension for the v2-only folks, too.

I am using this hack on a stress test of an NFSv4 HA server
for a few days right now. The test shuts down heartbeat every
15 minutes on every other server, and starts it up again 2
minutes later. I cannot say that NFSv4 performs very well in
this test, but there were zero problems with the bind mount.

Many thanx

Harri

IIRC, bind mounts were broken in the Filesystem RA until the
beginning of 2009. Take a look at this changeset (at
hg.linux-ha.org/agents) and the corresponding bugzilla for more
information:

Yes, I've noticed that, but since the version you're running is
rather old, couldn't find it of any use there either. If you take
a look at the changeset, you'll notice that bind mounts needed a
bit more fixing too :)

Good!

That doesn't look bad. AFAICS your changes are in the new
"experimental" Debian package for Heartbeat 2.99. There is
an excellent chance that this becomes a part of the next
Debian release.

Many thanx

Harri
