My lecture about S2D at 3rd SysOps/DevOps meetup in Wrocław.

Recently I’ve bitten quite hard into Storage Space Direct (S2D) Hyper-V clusters. Surprisingly I was also asked to prepeare some lecture on the SysOps/DevOps 3rd meetup and as at that time I was preparing to upgrade my MCSA to 2016, lecture about S2D was quite a good idea as it was covering some materials.

Here is me showing how good piece of an idea it was ^^

Here it is (might be harder for those who do not know Polish language ^^):

I added some pieces of information post factum, here they are:

  1. In Windows Server 1709 it is possible for data to migration from capacity tier back to the performance tier, operations that decide when this happen are writes – not reads – more about it >> here <<
  2. I told that there is no place showing associations of cache drives to the capacity drives – well I was wrong at that time, no longer than 2 days after the meetup I’ve found out this mavelous article by Jan-Tore Pedersen – thanks Jan! ^^

I am happy I had opportunity to hand over a copy of own book, this was my first time I was actually signing something to someone and this person was not a police officer and the paper was not a ticket, YAY!

Last year happened that me and my MVP colleague – Jacek Doktór wrote a book together. If you are interested in buying please visit Microsoft store as prices on Amazon seems to be a bit higher.

One copy of this book has been handed over to a lucky man who answered my PowerShell question at the 3rd meeting of SysOps/DevOps in Wrocław

My another marvelous colleague Mateusz Czerniawski was talking about all the PowerShell magic for testing and maintaining your infrastructure (for him also movies and presentations soon available ^^). BTW Matusz is a speaker on the upcoming PSConf.eu! Woo-Hoo!

What if Optimize-StoragePool doesn’t work with the “-WhatIf” switch?

Just recently I was running optimization job on S2D pool, so lead by curiosity I wanted to start it with the “-whatif” witch, like this:

$UniqueId = (Get-StoragePool | Where {$_.IsPrimordial -eq $false}).UniqueId
Optimize-StoragePool -UniqueId $UniqueId -whatif

I have found it on this wonderful blog:
http://www.darrylvanderpeijl.com/storage-spaces-direct-needs-rebalance/

And guess what? It started to do the job…

So be aware about that once “testing” the Optimize-StoragePool cmdlet.
