Troubleshooting Storage Spaces Direct Failover Manager with Get-ClusterLog – #StorageSpacesDirect

Posted by John O'Neill Sr. | Jun 17, 2019 | S2D, Windows Server |

Hey Checkyourlogs Fans, Today, I just wanted to share with you a super easy way to get detailed information about what is happening inside of your Storage Spaces Direct Clusters. We are facing an issue with one of our clusters where the “Network is Partitioned” for the Management Network. We would run a command Get-ClusterLog to generate the cluster.log file and review it for diagnostics. Unfortunately, this generates a rather large file with extra data we don’t need. For us, if we can reproduce the error message or problem and run the following: Get-ClusterLog –Node Node2 –TimeSpan 15 -UseLocalTime...

Filter Out Local AD Users to Not Sync with Azure AD

Posted by John O'Neill Sr. | Jun 17, 2019 | Azure, Office365, Windows Server |

Hey checkyourlogs.net fans, today’s post covers a common “ask” from those synchronizing on-premises Active Directory with Azure AD: how to prevent certain local objects, specifically users, from synchronizing to Azure AD. Use AD Connect’s filtering capabilities, that’s how! In today’s scenario I’m going to prevent the SystemMailbox account created for Exchange from synchronizing to Azure AD. I’ll set a value on an existing, but unused attribute found on the SystemMailbox AD object, then filter based on that new value. Let’s get this done! Step one is preventing unwanted synchronization while making changes. Do this by disabling the synchronization scheduled...

The Case of unable to connect to Storage Spaces Direct in Windows Admin Center because of WinRM errors – #StorageSpacesDirect #HyperV

Posted by John O'Neill Sr. | Jun 17, 2019 | S2D, Windows Admin Center, Windows Server |

Hey Checkyourlogs Fans, Today, we were working on a Storage Spaces Direct cluster that is managed by Windows Admin Center. We love using Windows Admin Center because it gives our administrators an HTML 5 interface with rich reporting and performance history. When we attempted to logon to the cluster this morning, we received the following error message: Connection to remote Server <Server> failed with the following error message: WinRM cannot complete the operation. Verify that the specified computer name is valid, that the computer is accessible over the network, and that the firewall exception for the WinRM service is...

The Case of low Disk Space on Windows Server R2 File Servers – Enable Dedup – #MVPHour

Posted by John O'Neill Sr. | Jun 14, 2019 | Veeam, Windows Server |

Hey Checkyourlogs Fans, Today, we have a quick post just reminding you that if you have Windows Server 2012 R2 File Servers are not able to migrate them to Server 2019 yet. You can still fix issues like lack of disk space with good old deduplication. Deduplication has worked for us like a charm on NTFS volumes, especially file servers for 7+ years now. We run it in production, and it makes a big difference. This week we faced an issue with a customer that was looking to convert virtual machines using ISCSI and Passthrough disks with Veeam. http://www.checkyourlogs.net/?p=66163...

The Case of Troubleshooting and poor VM Performance via Windows Admin Center – #MVPHour

Posted by John O'Neill Sr. | Jun 13, 2019 | Windows Admin Center, Windows Server |

Hey Checkyourlogs Fans, Today, I wanted to write a very quick post showing how you can use Windows Admin Center to quickly diagnose issues with poorly performing Virtual Machines on a Storage Spaces Direct Cluster. We had a call come in from a customer today that their SQL Server in production was running a bit sluggish on our all flash (NVME) S2D Cluster. Step 1 – Open Windows Admin Center and browse the Virtual Machine Summary Tab. What I noticed right away is that my CPU looks fine only 16 % utilized and none of my VM’s appear to...
