[Ocfs2-users] Question about increasing node slots

[Tim Lank]

We have a test 10gR2 RAC cluster using ocfs2 filesystems for the
Clusterware files and the Database files.

We need to increase the node slots to accomodate new RAC nodes.  Is it
true that we will need to umount these filesystems for the upgrade (i.e.
Database and Clusterware also)?

We are planning to use the following command format to perform the node
slot increase:

# tunefs.ocfs2 –N 3 /dev/mapper/mpath1p1
