Adds nodeid symlink support to gfs
Description of problem:
ATIX uses nodeid as a reference for context dependent pathnames in their shared
root configuration and setup. This patch adds the nodeid as an option to the
context dependent pathname code.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
We had discussed this patch before and we'd come up with some issues.
"o The nodeid in gfs is obtained from cman kernel module (and called "nodeX"
where X is the nodeid) and thus makes gfs dependent on cman. This is not a good
thing for non-clustered gfs deployment. Also, the node-id attribute is
cluster-specific and doesn't really make sense in a non-clustered gfs installation.
o Moreover, even in a clustered environment, the nodeids change over
cluster-restarts. So, if a node was looking at one location for its files using
@nodeid, after a cluster restart @nodeid may no longer point to that location."
As I figured out later, the second point is a non-issue because we can force the
nodes to have specific nodeids by explicitly declaring them in the cluster.conf.
Do we still need this feature?
Nodeids can be hard-wired to nodes in CCS. In fact we will insist on this for
RHEL5 (ccs_tool has an subcommand to add them).
done. added patch to RHEL4 and STABLE branches.
