[drbd-mc] Cannot input block device when adding a Filesystem OCF resource.

[Caspar Smit]

Hi Rasto,

When I add an OCF heartbeat Filesystem resource to a group I need to input a
block device.

This field is a drop down menu with filesystems that drbd-mc detects, I
cannot enter something manually.

drbd-mc does NOT detect logical volumes (like /dev/vg0/lv0) to use as
filesystem allthough it does have a filesystem.

It would be nice if drbd-mc detects lvm volumes too AND that it is possible
to enter some device manually (without having to depend on what drbd-mc
detects)

Thanks in advance,
Caspar Smit

Hi,

It is actually supposed to detect it, so you may have hit a bug. But first
check that you have the the same logical volume on both nodes. If you
don't, it doesn't appear in the list of block devices. Thinking about it,
I should loose this requirement.

The logical volume resides on a DRBD master/slave resource so it cannot be
visible on both nodes at the same time.

Secondly it would still be nice to have the ability to enter some device
manually too.

Kind regards,

Yup, you are right. The LVM devices on DRBD wouldn't show up. I have some
bigger plans for setup like this, but for now, I should at least allow to
enter it.

Hi Rasto,

Is there already a development version available with this fix so I can
test?

If not, do you have an ETA when it will be available?

How about..., right now. :)

There is a new test version dmctest-0.9.1.dev.6.jar here:
