You should be able to mount the same device in X different nodes. Run =
an
enbd-server instance pointing to the same underlying device for however =
many
nodes you want connected to it. Then run enbd-clients to attach to =
them.
What you should end up with is read-write block devices on each of your
nodes pointing to the same thing.
To test it, do stuff like "echo `date; hostname;` > /dev/whatever" =
From
each node. Then cat the device. You should see what you put there =
from
each node.
Once you get that working then it's time to fiddle with the Oracle =
stuff.

Subject: RE: [ENBD] (no subject)
Here we are... First at all, I=B4ll explain what I want to do; and =
what I=B4ve
done nowadays.
All the tests I=B4ve done with nbd (not enbd) have been only using one
node
working as server and as two clients, mounting the same device in to
differents /dev/ndX, with the device mounted (/dev/hdd4), and sharing =
it
through samba. All rigth, just testing, maybe to much for enbd (I =
don=B4t
know), but ... despite of the deadlocks that halt the system (It =
isn=B4t a
good idea to mount the device in the node that owns it), ... I was able =
to
create a half of the database (400 megas).
I need to mount the same device (read/write) in two diferents nodes
(If
it=B4s possible, the cluster software and the cluster filesystem should =
do the
rest). I=B4ve download the nbd-2.4.30-current version of enbd and untar =
it.

2.4.9 is too old for me to know if current versions of enbd compile
against it or not. It's pre- the great VMS changeover.

(Oracle

You'll have to tell me if it compiles or not. I'll make changes for you =
if
modifications are needed.
