In my previous post, I talked about BTRFS, a modern and exciting filesystem for Linux. In this new post, I’m going to give you a quick walkthrough on what you can do with it.
Switching to a new filesystem is never a task that is done with a light heart. We have our own trusted good old filesytem, that has maybe limits in features and performance, but has never let us down. New filesystems are available, and they promise wonderful things. But as much as we are fascinated by them, the big Q “Should I trust it?” comes to mind when we just start thinking about moving to a new filesystem. In Linux, this question arises everytime BTRFS is involved.
In 2012 I wrote a blog post that became really popular: Installing VMware tools on Centos 6 via yum. Few years forward, and today the preferred tools are the open sourced ones available natively in many linux package managers. So, some may think to switch from one version to the other one for their existing virtual machines. That’s what I’ve done in some of my virtual machines, and here is the process.
CentOS is known for not using the latest versions of the Linux kernel. If you need up-to-date versions, you need to configure the OS to use different repositories.
I started to blog when I was already working on virtualization technologies, but before this I was a security consultant, and I still hold my CISSP certification. So, for once I’m writing something about security more than virtualization, because this news about SSL totally deserves an article. TLS is hard… let’s keep SSL for a […]
If you have a large environment that is constantly changinh, you may want some automation to test VMs every day with Veeam SureBackup. Here’s a solution to do so.
Since Veeam announced the Scale-Out Backup Repository technology coming in Veeam Backup & Replication v9, I’ve been asked already multiple times to give some practical examples on how to leverage it. Let’s see together one interesting way to leverage the “performance” policy available in Scale-Out Backup Repository.
In 2014, in a presentation I’ve done, I’ve said to people that in 2-3 years new and cheaper flash memory would have become the stardard solution for general purpose disk storage, thanks to a price per GB comparable with spinning disk. Seems that I was right after all.
