Roll Your Own Thunderbolt 3 External SSD

Mac, Technology, Virtualization

I recently received a 13" MacBook Pro with an internal 512GB SSD. I support a lot of different products and need to virtualize many different environments to do so. Naturally, 512GB fills up pretty fast when creating a bunch of virtual machines so I started shopping for decent external SSDs. It seems silly to waste my money on SSDs based on USB 3.x interfaces as they generally top out between 500MB/s to 1050MB/s when we now have Thunderbolt 3 which is 4 times faster at 40Gbps. The Sticker shock of these new TB3 SSDs is a bit much as at the time I'm writing this, the Samsung X5 2TB SSD is a whopping $699.99. I just couldn't justify this purchase and started doing a bit of research. Turns out you…

Installing systemtap on CentOS 7

I recently had the need to install systemtap on one of my CentOS 7 VMs and the process isn't as straight forward as it should be. It seems not all packages needed are built for all revisions of the kernel. After much searching, I managed to get this working and wanted to archive this procedure. (more…)

FreeBSD / FreeNAS Clone Jail

BSD, Technology, Virtualization

I recently had the need to update my shiny new FreeBSD jailed server because I wanted to migrate to WordPress. I didn't want to bring down the existing server while I did the install and converted my content so I managed to clone my existing jailed server using warden: warden export name_of_jail --dir=/directory_for_warden_file This will take a while... Once done, you can import the warden file creating a new jail: warden import jail_warden_file.wdn --host=jailbird --ipv4=192.168.1.105/24 You've now got a cloned jail and a template for creating other jailed servers.
