No problem. :-)
The main points of having a RAC cluster as I understand it are
availability and scalability on low-cost systems. Shouldn't ocfs2 have
the ability to perform online expansion like this? I know that Red Hat's
GFS can add journals to accomodate new nodes while the filesystems are
online (gfs_jadd -j Number MountPoint).
Online add node slots is in our todo list.
What is the downside of installing a starter two-node cluster with ocfs2
filesystems configured for say 8 node slots? The documentation seems to
suggest that you not do that
The only downside, if it can be called that, is space occupied by unused
journals.
However, tools 1.2.7 will provide offline remove node slots which should
help
with that.
