[Ocfs2-users] Moving a o2cb single node to clustered

[Marco Scacchi]

About your question:

*Is it possible moving a partition formatted with ocfs file system as
standalone (I have only one node) to a clustered one ?*

I'm not the best support you can found here,
but, if you are speaking about ocfs2, the differences between clustered or
not filesystem should be a mount option ( -M local, or maybe you have
already a one node cluster )


about this:

*The question is this:  I have to add a disk on the server, that soon
will be clusterized (Pacemaker+drbd+ocfs).
Now I configured DRBD (primary/secondary at the moment) and I have to
format it, but I'm in doubt if it's better to have ocfs working
standalone o clustered, but without a node.*

I'm not confident to understand this one.
If you need OCFS2 over DRDB, i think you can't save your filesystem (backup
it !!!!).
Maybe your setup (primary/secondary) isn't your goal to use a clustered
filesystem.
DRDB primary/secondary is the best choice to have an ext3 filesystem which
can be mounted on the first node OR on the second node,
if you need a concurrent filesystem, mount on first node AND second node,
you need an active/active DRDB configuration.
To format an drdb device with ocfs2, you need to create it.
Here http://www.drbd.org/users-guide/ch-ocfs2.html, you can found more
detail.
