[Spacewalk-list] Redundant spacewalk servers

[Paul Robert Marino]

Hey just wanted to give a quick status on this to any one intrested
so far its going well there are a few gotchas I discovered like this
little tidbit with PostgreSQL 9.1
https://www.redhat.com/archives/spacewalk-list/2012-February/msg00052.html
but it seems to initially be working
I still have to figure out how i want to handle this bug
https://bugzilla.redhat.com/show_bug.cgi?id=836374
some people have worked around it with xinetd but I think an iptables
DNAT rule would be more efficient
but ill probably put both methods in the howto

For sharing the file systems I'm using Gluster. so far its worked so
well its already spreading like wildfire in other projects

I still have one last thing need to look into for postgresql and thats is if the
"
local spaceschema postgres  ident
"
in the pg_hba.conf is needed after the initial install


Ive been taking notes as I go and will probably write the wiki article
in the next day or two.
