So I'm new to the user group, never chatted but been listening for a month or so.
My work is trying to build a Cloudstack setup, on a DOD network (fully secured), and I'm trying to do it with very little Linux experience. We have a couple people I can go to with experience that can help when I run into trouble and I'm been beefing up my skills for sure, but I was hoping that someone could give me some help on what they do to troubleshoot when things go wrong and some of the top issues with that do/can go wrong. Also looking for good resources going forward besides a lot of the ShapeBlue or Cloudstack documentation (I've been to those sites and both are very good for basic setups) I've looked at the Cloudstack troubleshooting guide and besides doing the grep command on the management log it's not much help. Some of the issues I'd like to discuss or have help with are the: File permissions What needs to be set to the cloud user for it all to work Web GUI How to check if it's running, what to check when it's not working at all. Management log grep commands that actually help Kinds of logging most people have on/off, do we need debug/info etc Size of the "secondary storage" for a production environment with say max 100 VMs/Instances Securing the infrastructure - Linux, sql, etc with STIGs Anyone done this? Maintenance mode - Should we put a host in maintenance mode anytime we want to do work on it or reboot it? I've seen issues where the host never comes back into the fold if we just reboot it. Any other kind of common issue that may occur setting this up and how to fix it. Right now when our test environment when something messes up the environment the normal procedure if start/stop management server or rebooting doesn't fix the issue is to wipe and reload. Also, I know ShapeBlue offers formal training, but is based in the UK, anywhere else offering formal type training based I the US or is that the only option for some actual training over youtube videos of people reading the initial setup. I've currently been able to get the management server up and running, with the basic networking, and have 4 different hosts added using NFS storage on each for the primary and the secondary storage being the management server's internal storage. Our final environment is going to be something similar with 6-8 Dell servers (good ones) so I'm not sure if this is the best setup or not using them all like a HCI like environment where everything is all in one. Appreciate any help and support. Gary Morrow
