Turns out, that said colleague has been playing with NFS on one off the web nodes, thus apparently rendering the remaining nodes offline (or semi-offline).
Now after all web nodes hung themselves, we had to hard reset them, now everything is tingly again .. *yay* for a great first day …
I’m coming back today from a six day vacation in the warm south (that is Stuttgart), back at work and find three sheets of paper on my desk. Two tell me something I haven’t done yet, the other one tells me something I haven’t seen yet.
One of my colleagues had to restart one of our web nodes and now the thing can’t mount the logging volume (and thus, logrotate / awstats failed to do it’s job). OCFS2 ain’t spitting any error messages, when trying to mount the volume you see it joining the domain the volume belongs to on the other nodes, so from a first glance at things .. nothing is wrong ?
One thing I’ll have to add is, that you can’t reboot the box cleanly (as in you have to use the power button, so I figure something is either stuck or something is malfunctioning ..) *shrug*
As I mentioned before, we decided against the Citrix Presentation Server solution in favour of the 2X LoadBalancer and ApplicationServer combination. You’re gonna say, but Citrix does the same and it’s only one “application frame“. 2X is exactly the same.
