I think before we rework this, we may want to readdress the nodeid issue
more completely.
Right now - short of chrissie's first patch -, the in-kernel DLM doesn't
like even 31bit nodeids, and will blow up quite readily. So, whether it
blows up with 31bit nodeids or 32bit nodeids doesn't really make a
difference, as the admin has to auto-configure them anyway ;-)
The in-kernel code will need fixing anyway before auto-generation works
in practice.
We can thus either directly fix it so that 32bit work (and this patch
becomes superfluous), or go all the way to 128bit UUIDs (which can
either be safely auto-generated or use the node's IPv6 address), the
latter being IMHO preferable but requiring rework of openAIS too.
Regards,
Lars
