I remember a few years ago talking to the marvelous Jeffery Snover about PowerShell – and my mind was blown. The possibilities of scripting, remotability, the modular design – were all magical and innovative.
This week I’ve been updating servers on my Hyper-V infrastructure – most of them are server core – reducing the memory and patch requirements significantly.
Using a PowerShell I’ve been able to upgrade them all to Windows Server 2012 R2 with minimal fuss and effort.
I took advantage of the enforced, unplanned outage to update SLES 11 from SP2 to SP3.
All good – the only tiny gotcha was running the MySQL upgrade manually at the end.
Otherwise – looks happy so far.
I got bitten by the udev GUIDs when I did the move/upgrade/move back of my on-prem blog server this morning.
What should have been a simple evacuation of some VMs, upgrade the host to Windows Server 2012 R2, move the old VMs back in place – turned into another episode of handcrafting grub entries and checking that everything mounted back up correctly.
I got bit by this before – and I need to drill into the best practices for using SLES 11/udev in a virtual environment.
