This is really just a place holder that I’ll be updating while I examine the various was to skin the cat called storage clustering. My main focus will be for High Availability and as a shared storage back end for virtual machine clusters. Also the ability to roll as much myself for a minimal price… Continue reading Storage Clustering….a living research project
These instructions will create a bootable install medium for the installation of a operating system using a .iso file downloaded from the network, the dd command and a standard USB stick. You need root level access (to run the sudo command). This covers Linux [for MacOS see Bootable USB install device in MacOS] Let us begin… Continue reading Bootable USB install device in Linux
So, I’ve walked into this one a few times when compiling a new kernel for the first time after a new distro install. Each time I shake my head and can’t believe I did again. When compiling a new linux kernel and fails with the following error fatal error: openssl/aes.h: No such file or directory… Continue reading Kernel fatal error: openssl/aes.h
Ok. I last posted about how to find the full URL to your icloud calender so you can connect and sync to it using third party apps. This required diving into a .plist file on a system running macOS. It is still possible to gather the information needed to to string together the “secret” address. … Continue reading Apple CalDAV address…without .plist

(geez just had a flash back to the days of RPM dependency hell when Red Hat first rolled that out) Though, every now… Continue reading PPA Public Key Error
I was never a fan of FUSE performance (looking at you QNAP), the performance boost in block device access for Qemu/KVM based hosts using POSIX vs FUSE is impressive. Gluster as a SDS solution for oVirt self hosted engine is worth investigating for a multitude of use cases. My own testing for HA replication has… Continue reading QEMU-GlusterFS native integration
Hosting a virtual machine inside a virtual machine KVM trickery for conceptualisation and testing. If your server/host supports VT-x, it goes to say so should the guests. When trying to setup a oVirt node with hosted engine in KVM I was coming to a grinding halt with the following error. [ ERROR ] Failed to… Continue reading Nested Virtualisation
I installed Wireshark the other day on Ubuntu 16.10 so I could analyse what is “going over the wire” in GNS3 and later on physical network topologies. Unfortunately, due to the way I installed wireshark, the way it handles the security of low level device access (PCAP) , coupled with a touch of me not… Continue reading Wireshark capture permission errors
After having a running battle with my, what turns out, cheap Chinese CSR clone bluetooth USB adaptor (maybe more on that in another post). I purchased a more expensive adaptor to trouble shoot some issues. The time round I picked up a Targus brand from the local office supply store that based on the Broadcom… Continue reading Bluetooth USB dongle firmware error in Ubuntu 16.04 – 16.10
