We’re currently having a *really* weird problem with our VM’s. Sometime last week, SUSE released a kernel update. Now, once you install it and you reboot the selected VM with a DVD/CD image present, you’re gonna see this:
msg.vmxaiomgr.retrycontabort.unkown
The only workaround so far has been to unmount *any* cleanse any CD-Drives attached to the VM. And yes, this is reproduceable, even reinstalling from scratch doesn’t change the fact, that after installing the patch the VM quits working.
I also know, SLES10 SP2 ain’t officially supported yet by VMware, but I’d still suspect it to just work and not produce such weird errors. The only thing I found so far is this VMTN thread ..
Lucky us, VMware just today released Update 2 for VirtualCenter and ESX, wherein SLES10SP2 should be officially supported!

Well, it turns out that my thought was ultimativly flawed. When defining the hostgroup_members in the lower tiers, nagios is association the checks from the lower tier with the upper tiers. Thus propagandating all checks upwards, and me ending up with ~250 checks instead of ~150.
Gonna have to try to define the dependency backwards, maybe that’ll help. But that’s a topic for Monday. Guess I’ll finish viewing Ghost in the Shell - Stand Alone Complex first.

As I wrote earlier, I recently virtualized our nagios. Along with that came a complete “redesign” of how checks are applied. Up till now, I defined checks for each and every single server, thus ending up with ~25 files, each holding roughly 6 checks which are in the same file just sorted by hostname.
As you can imagine, it gets quite confusing with that amount of checks (~150). So the last two days I spent on reorganizing (with Visio), on which object/hostgroup placing a check would make sense. Now, this is my first result of two days planning, reorganizing, reordering and moving hosts into different hostgroups.

Thanks to Josh (and Chris I think), realizing the above is gonna get quite easy. Gonna talk about the config layout itself about once I have it all wrapped up. Stay tuned!
