Rubrik : Getting CDM Upgrade History

Image
Background During our ISO audit last quarter, I've been asked to provide a list of the various date of our CDM upgrades. This way they could match with our internal Jira tickets to confirm we are following the process. It was not easy and I had to raise ticket with Rubrik to get support accessing that information. Could it be easier ? I believe so ;)

Test : Pale blue Li-Ion Batteries

Image
Background Batteries can be expansive and environmentally unfriendly. Of course, alternatives exist but none of them are truly satisfying. Rechargeable batteries are not providing more than 1.2V, they do not last long and require frequent charge cycles. While scrolling my Facebook feed, I found an interesting ad about a company called Pale blue providing Lithium Ion batteries with the standard batteries form factor with 1.5 V and a standard micro USB port to charge them. Is this the Grail ?

Nutanix : Get Size of AHV Snapshots

Image
Background While working on a AHV cluster, you can notice that, with time, the storage decreases. This is obvious, all VMs are using thin-provisioning by default. Doing some cleanup and maintenance is required on every IT systems and Nutanix does not escape the rule. One area where we are not focusing enough is the snapshots we are creating and most of the time forgot !

Rubrik : Generate Executive Summary

Image
Background It happens quite often that my management is asking for details about our Rubrik usage. Not only a single cluster, all clusters ! This is time consuming (boring too) to go on each clusters, collects the details, compute total usage, protection status, storage savings ratio .... I think you know me now, I'm fan of automating boring things. This task does not escape to the rule ;)

Linux : Rocky Linux

Image
Background I believe most of you heard about the new Red Hat strategy around CentOS ? One of the favorite OS for Linux testing in the Enterprise ? Yes, CentOS used to be the most stable and conservative environment in the Red Hat family (CentOS, Fedora and Red Hat Enterprise Linux - aka RHEL). When Red Hat announced they are going to shift CentOS to a rolling release exactly like Fedora for the end user world. Many Sysadmin out there were wondering how to address that issue. I believe we have a solid candidate.

Nutanix AHV : Running Windows 11 beta

Image
Background This is not a big secret, the next famous OS from Microsoft leaked over the Internet few days ago . Windows 11 beta. I'm not a Windows fan, but I'm curious about anything technology related (as you already notice since you are here). I was wondering how it looks and what is the experience. The only quick and easy platform that I have with me is a Nutanix AHV cluster. I wonder if it works.

Php : Easy Documentation Generator

Image
Background We all been there, and probably me first. When creating codes, the documentation consist most of the time by the comments in the codes ... *sic* For small projects by couple of hundreds lines this is ok but when your project start to hits some 10 thousand lines, this is becoming an issue. There are multiple of initiative on the market to help generating proper documentation (phpDocumentor, phpDox, ....). But they are all massive and not intuitive. I decided to create something ultra simple providing a php source file containing all your function, and an output file that will generating markdown syntax. Ideal for GitHub.

WiFi : TP-Link Mesh WiFi Deco M5

Image
Background I don't know about you but my house is not easy to cover with good and strong WiFi coverage. I've tested almost everything : central strong AP, different WiFi networks, extension via power line, multiple APs with same SSID... all my attempts to get a solid coverage were wrong and this is very frustrating. The dream would be to have multiple hotspots with the same SSID and a technology that allows roaming between APs like mobile networks ... but wait !

NextCloud : File-based Restoration

Image
Background Nextcloud is a well known file share platform, open source, freely available with nice syncing features. It is the OwnCloud "successor". The platform is providing a web based portal to manage files and shares but as well syncing clients are available on most OSs. The use case I'm trying to achieve here is the file-level restoration. Most of the time, the backup is doing a full VM backup with all files. But what if a user is requesting a restoration of a single file or directory ?

Linux : Mount an Bucket on a Linux Machine

Image
Background If you are already using an object store, you probably have a use case where you want to access the content of the bucket directly from the Linux filesystem. In my case, I'm using Cloudian, and I would like to directly read/write content from/to my Linux machine. Cloudian is object store and Linux is using traditional block store. But, wait ! it is possible to mix those environments !
