I want to know whether _datavolume can be used for non-database
filesystems. Oracle support is recommending the use of _datavolume
along with _netdev
In reading the documentation, I have found the following which
suggests _datavolume should never be used for anything other than the

Which distribution is this? The distros it is working right now include

the bits for rhel as yet.

Hi Sunil,
yes I know about ocfs2.pcmk, but it was absolutely not working
in previous releases, so :
- is this stack ocfs2 for pacemaker maintained , supported ?
- is it really used on some customers clusters ?
Thanks

Hi,
sorry but I don't understand, do you mean that even if the linkcom
problem is only
on node1 side (i.e. if the Eth Board has a breakdown) ,you mean that
this will
lead to a self-fence of node1 whereas it is node 0 which has the real

ocfs2 is a shared disk clustered file system. As the disk is accessible
by all nodes, there is no need to keep the data in sync. Instead the fs
needs to ensure nodes coordinate access such that multiple nodes reading
and writing concurrently do not corrupt the fs.
You may want to read the ocfs2 1.
OCFS2 does not do any of that - It's just a filesystem. What is your
underlying disk architecture? FC-SAN?

I'm considering using OCFS2 on some image servers (~25M image files)
to keep them in sync across all the nodes (currently 7). The
questions I couldn't find answers to are:
1) How many nodes can I lose before I can no longer access data?
1a) Is there a way to increase the number?
2) Is the data m

You are absolutely right. Sorry about that. I think I didn't have enough
caffeine this morning ;-).
The procedure is when you have available slots and just want to add a
node to the cluster.
Any change to the superblock needs to have the partition offline.
You don't need to umount to upgrade dat
So since tunefs.ocfs2 is the tool that actually does all of the work to
add more slots and the tunefs.ocfs2 man page states:

tunefs.ocfs2 is used to adjust OCFS2 file system parameters on disk.
In order to prevent data loss, tunefs.ocfs2 will not perform any

The console does that (You can use the console to add a new node).
tunefs.ocfs2 is actually the tool that will change the superblock to add
more slots (see the man pages) and it is called by the console (a more
user friendly interface) to perform the action.
o2cb_ctl only defines the new node(s) o
So does the o2cb_ctl command touch the ocfs2 filesystem superblock and
increase the node slot value in this example?

Can someone correct me on my understanding of the order to take down a cluster?
Lets say I have a server exporting a drive via iscsi, and 4 nodes

Now I want to shutdown all my machines to do maintenance or what have you.

Just create a one node cluster.
However, if you were to mount two mirrored volumes on the same node,
you will have problems as detailed in this thread:
