I was planning to Clone CentOS 6 "Updates & EPEL repo and skip Base
repo. Will those 2 be good enough for basic system packages  ?

You need the Base channel. The Updates channel only has updates. So, any package that hasn't been updated will expect to be pulled from the Base channel instead of the Updates channel. Also, when a new point release comes out, that's when the Base channel gets updated.

Personally I stay far away from putting EPEL directly into a production environment. If EPEL packages are needed, I put them into a custom channel, and deploy them that way. Depending on your tolerance for breakage, your results may vary.

We have different minor version distinction in distributions. Like
CentOS 6.5, CentOS 6.7, are there any considerations that needs to be taken
?

Just that the upstream Base channel gets updated when a new point release comes out. So, if you want to maintain your own CentOS 6.5 Base channel, for instance, be sure to keep that clone around. The same goes with the Updates channel. You'll want to clone the Updates channel to match up with the version of the Base channel.

Is HA important ?

That completely depends on your needs. I don't think Spacewalk can function as an HA service without some serious kludges. If availability is important, you might want to stand up one or more Spacewalk Proxy systems, and point your systems to those instead of directly at the Spacewalk server. That way if the Spacewalk server is offline for a while, anything cached by the Spacewalk Proxy will still be available to clients.

Hi

We have set of around 200 servers and we are planning to use SpaceWalk for
Patch Management.

Most of the Servers are based on CentOS 6 and I had few questions before I
can actually setup for Production environment.

i) I was planning to Clone CentOS 6 "Updates & EPEL repo and skip Base
repo. Will those 2 be good enough for basic system packages  ?

ii) We have different minor version distinction in distributions. Like
CentOS 6.5, CentOS 6.7, are there any considerations that needs to be taken
?

iii) Is HA important ? We plan for weekly snapshots of the Server which suffice our requirement as it won't be used on daily basis. If anything
happens, we can restore the snapshot.


Any help will be appreciated!
