Is My Satellite Server Actually Replicating Content?

Hello everyone,

I have recently inherited responsibility of our young Zenworks infrastructure in a college environment. We've been having imaging performance issues in our progressive transition from multicast Ghosts to unicasts ZMGs. Short term, multicasting in our computer labs is not a solution. A couple of issues have come up. We have 3 primary servers virtualized in one campus and 1 satellite virtualized in a secondary campus but all are fiber linked. Only one primary server seems to be doing all the lifting so we're looking at redistributing roles and migrating primary servers to our secondary campus but this will come later.

Right now, I'm looking at our satellite server which has authentication, collection and content roles. We're just not sure it's actually helping distribute bundles in our secondary campus to offload our heavy lifting primary server. I can see it's at the top of the "Closest Servers For Roles" list on our agents so "location" seems to be working for our secondary campus. Here's what I can't figure out:

Some old and new content hosted on the satellite seems to be "unavailable" and I'm having a hard time understanding why other recent content's status is "available". The 3 primary server contents are all "available". "Content Type Replication" for "Default" type content is set to run daily at 1AM with a duration of 60 minutes directly on the satellite with no throttling.

Please see the linked images from my Dropbox:

https://www.dropbox.com/s/zfe9en1u3n6h8zy/Status%20Unavailable.png?dl=0


  1. Why is it that some content is "unavailable" on the satellite?
  2. Is the short 60 minute duration to blame?
  3. What is the prefered method to find out where my content is coming from during bundle installations aside from Windows Resource Monitor?
  4. Can I switch my satellite's parent primary server transparently?



    Thank you for your help

Re: Is My Satellite Server Actually Replicating Content?

Don't Do this............
"we're looking at redistributing roles and migrating primary servers to our secondary campus but this will come later."

All Primaries should be in the same physical location as close to the Database Server as Possible.

The only exception is if you have a "Disaster Recovery" location with a DB and Primaries that are basically configured as "Off-line" and flipped on if the main data center goes down. (Fire, Natural Disaster, etc..)
I'm not doing to go into details on how to set this up, but except for such a configuration all primaries should be in the same datacenter as the Database Server.

---------------

#1 - Verify the Content is available on the Parent Primary as well. (Or the Server From which the Satellite is configured to pull content. (This could be Parent or based upon location rules or both, depending on configuration)
#2 - Try increasing this value to 4hrs. Especially since this only runs once a day. This may resolve the issue.
#3 - If on Debug, the ZMD-Messages.log will usually indicate where it is pulling the .ZC (content) files from.
#4 - This should not be necessary...A single sat will put almost no load on a primary and if need be you can change where it pulls its content from almost completely eliminating load.

If the content looks good on the parent and the 4hr windows does not help.....

You could try resetting the satellites content database to see if that clears up anything.

#1 The content is listed as available on the Parent Primary.
#2 I've adjusted it to 4hrs.
#3 Im not familiar with "ZMD-Messages.log", I'll do some reading.
#4 Very well, thank you

Should I try to use "zac wake-cdp (cdp)" to replicate manually and troubleshoot?

Don't Do this............

I understand your point about the database server proximity and I will readjust our assessments accordingly. Our evaluation is still in it's infancy and I'm still reading "ZENworks Configuration Management - Best Practices Guide ZENworks 11 SP3". Can we still redistribute our roles though? PXE and Imaging is all done from one primary server right now. This is also the case with our secondary fiber linked campus. I'm hoping I can do some load balancing and improve performance by having more than one PXE/Image server. Would the satellite handle this in our secondary campus if the hardware is right? In our environment, we need to be able to image a significant number (60+) of computers in different campuses on short notice (same day) without affecting user experience(mostly login times).

Thank you very much!

Re: Is My Satellite Server Actually Replicating Content?

Here is a TID that details where to find various logs.
zmd-messages.log is the core "Agent" log.
The Satellite Services primarily run on top of the core agent.

Debug Logging and zac wake-cdp may help in troubleshooting.

OK No worries about that then, I've seen some issues where on Linux some memory config files need tweaking.
Does not apply to Windows.

Re: Is My Satellite Server Actually Replicating Content?

Hi guys,

Just a quick update to clear things up. It's fixed! :cool:

I recently got access to remotely log in to the our satellite server. Apparently, the content-repo had a symbolic link to a VM volume that was staying offline after reboots for whatever reason. :confused:

It's a little embarrassing but I'm happy it's fixed!

Thanks for your help!

I've been more embarrassed.
After Spending an Hour trying to get a PC to recognize an external USB Device (Bios Updates, Bios Settings, OS Settings, Drive Searches, etc....), I finally asked a co-worker if they had ideas.
Took them about 5 seconds to go............It's plugged into your other PC...........
