Sometimes after a XenServer restart you might find your host takes a long time (many minutes), to exit maintenance mode. This can be indicative of a problem syncing with the master server, but before you go about tears apart your XenServer install you should take a few minutes to see if it's running a disk check on one…Read more

I though I would write a quick article covering this error as I have not found this issue documented anywhere online and the error is not descriptive enough to hint at the cause. The articles online will have you going off on a wild-goose chase checking disk sector offsets and adding and removing your physical block…Read more
This quick tutorial covers how to create a custom login banner, or what's formally called 'message of the day' or MOTD in the Unix world. This will help you more easily identify what host you're logged into and give you an idea of it's basic systems specs. It also looks pretty cool. Create the…Read more
As hard drives have become more and more commoditized and prices per TB continue to drop, manufacturers are under immense pressure to find ways to differentiate their drives and establish better profit margins. While drive consumers simply expect the drive to be fast and reliable, some manufactures seem to think that reliability is a value…Read more
The expected method for managing VM IP addresses in SmartOS is an orchestration system like Joyent SDC or Project FiFo, but both these systems have enough of a resource overhead that some people may choose to run SmartOS as a stand-alone hypervisor. As SmartOS is primarily a cloud platform it would be detrimental to the sytem…Read more

So that begs the question, why do we have to pay a…Read more
This is an abbreviated how-to on updating your SmartOS version when your existing install is booting from a USB flash drive. In this example we will be updating to 20150903T073920Z but you would simple replace the occurrences of 20150903T073920Z with whatever version you want to update to. Check your current version. # uname -a SunOS…Read more
With the advent of cloud computing the need to move away from large monolithic databases becomes more and more essential. Pure cloud environments don't scale vertically very well, so a large central database server is impractical and violates the design mandates of a pure cloud computing environment which requires using distributed increments of commodity virtual hardware, often…Read more
SSH keys are installed on your client workstation and once loaded into the FiFo management interface allow you to login to your guest virtual machines without the need for a root password. This authentication method is not only more secure but also more convenient than using a typed password. It is essential to get SSH…Read more
