This article was written a few years back, but never published – it was some work I was doing in my lab to try and get to grips around the work involved in creating a SAN with synchronous replication built in from scratch. It in no way should be used for production, but rather as […]
vSphere Update Manager – Cannot Scan Host
I have been testing out Runecast Analyzer in my lab recently – it’s pretty badass, you can set it up to scan your virtual infrastructure at a vCenter level and will scan your vC, VMs and hosts looking for KBs that may apply, security compliance and best practises. As you can see my lab isn’t […]
Deploying Dell OpenManage on ESXi and vCenter 6
If you’ve been reading my other posts of late, you will have gathered I’ve been building a new lab. I say “new”, the last one was a single R710 with a ReadyNas Ultra 6 attached. So essentially, this is my first REAL lab. It’s mostly based on Dell hardware; it’s cheap on eBay, I like […]
Windows Integrated Auth (SSO) fails in vCenter 6.0
If you’ve just spun up a new vCenter 6.0 appliance, have joined it to the domain and added a new identity source but have found that your integrated windows auth (the handy checkbox you use for SSO) isn’t working with this error: A General System error occurred: Cannot get user info Then it’s because the […]
Replaying Linux CLI commands with history
Very handy little snippet I discovered today, mostly here for my own reference in future. It’s handy to be able to re-play/re-submit commands that you’ve typed into the CLI before on your Linux box, to do this you can use the history command.
Deployment Options for vCenter Server Appliance 6.0
The new version of vSphere brings some major improvements to the vCenter management end of things, the main thing is that it is now a highly available solution (previously reserved for vCenter Server Heartbeat – a separate, now EOL, product VMware offered) that can run in two modes.
Utilising Kerberos/AD auth in Ubuntu 14.04 with realmd
It has, over the years always been quite a quandary to get SSO auth working from *nix->MS AD without a huge amount of fiddling and tinkering, but there is a new auth framework in town by the name of realmd. While tinkering with The Foreman recently it had dawned on me it would be cool […]
Enabling PXE boot options on Fortigate DHCP
I have been recently setting up The Foreman as a Puppet management front end to allow me to quickly provision Linux based VMs on my VMware cluster
Deploying Cisco VIRL on VMware Workstation – Caveats
I recently tried to deploy Cisco VIRL on VMWare Workstation 10 – the install instructions are for v8 – there are a few differences I noted.
Fix for CBT bug in VMWare Products
VMWare, as of writing, has a nasty bug that means your backups that run utilising CBT (hint: if you have basically any enterprise backup product worth its salt, it’s got CBT enabled) it loses track of the changed blocks when the VMDK reaches any Power 2 value of 128GB (128, 256, 512, 1024, etc.) which […]
