Hello Dominik

What you doubt about ocfs2 implementation (all doubt or at specific point) ?!, and what the Operating System ?!


2008/6/27 Dominik Vogt <dominik.vogt@xxxxxxxxxxxx>:
Dear List,

I'm thinking about using xen productive in our datacenter, i'm still
testing around with it. Now I got some questions, just for basic
understanding, we got for example this environment:

2 Nodes
1 SCSI Pool server (Connected via scsi to both nodes)

Now I want to build a "cluster" so i would like to make this:

Node 1 -> Primary   -|                          | --> domU 1 (LV/OCFS2)
                    |-> SCSI POOL 1.5TB (VG)   | --> domU 2 (LV/OCFS2)
Node 2 -> Secondary -|                          | --> domU 3 (LV/OCFS2)

So the reason, why I use ocfs2 is, because I access the same Disk with 2
Nodes via scsi. It would destroy the fs, if I use ext3 (normaly).
but.... I can't boot the domU's form a ocfs2 filesystem... So I tried to
setup a domU and installed ocfs2 into it, after that I cloned the system
into a ocfs2 lv, but if I start it, it can't find the root filesystem.
what else do I have to attend to get a system startet from a ocfs2
filesystem? Or is this the wrong way?

Regards, D. Vogt
