Windows server 2016 Fail over clustering node failure

May 26, 2020, 4:20 am

Good day, 

Hope someone can assist or point me in the right direction. 

Our 7 node failover cluster when unstable on Thursday last week. eventually we turned off all vm's and rebooted the hosts.

all working again :)

we then looked and the logs and see one of out hosts had a bugcheck and rebooted. 

logs we picked up is as follows 

started with event id 153 The IO operation at logical block address 0x1ac91a540 for Disk 19 (PDO name: \Device\MPIODisk19) was retried.

alot of them and then 

event id 1146 The cluster Resource Hosting Subsystem (RHS) process was terminated and will be restarted. This is typically associated with cluster health detection and recovery of a resource. Refer to the System event log to determine which resource and resource DLL is causing the issue.

followed by event id 41 The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

i get the following on the memory dump but can not make out what caused the server to crash.

 bug check code 0x0000009e parameter 1:ffff8d8f`15b58540 parameter 2:00000000`000004b0 parameter 3: 00000000`000000c9 parameter 4: 00000000`00000000

can anyone decipher these bug check codes?

Cluster with 2 hosts 2012 R2

Scheduled CAU fails with:

CAU run {4EFE116C-AB49-456D-8EED-F7EDC764DA49} on cluster Cluster1 failed. Error Message:One or more errors occurred while checking the status of Windows Firewall on the cluster nodes. Review the errors for more information on how to resolve the problems. Error Code:-2146233088 Stack:   at MS.Internal.ClusterAwareUpdating.Util.<CheckFirewallsAsync>d__3a.MoveNext()

If I run CAU "Analyze Readiness" ALL comes as PASS

If I run CUA by hand on same hosts with NO change to the system (not even reboot) it finishes OK

Anybody any ideas?

Extend log volume on server 2019 stretch cluster

We have a 4 node stretch cluster with shared storage.  2 nodes in DC1, and 2 nodes in DC2.  we have volumes replicating currently using a 20GB log drive.  We want to replicate a third volume, but it wants to use the existing log volume, which does not have enough space.  The current data volumes are continuously replicating without issue (125TB and a 40TB)  Can we just extend the log volume by 20GB?  If so, is it just a simple extend the volume or are there special commands for it?

Cluster Shared Volume Cannot be Moved

May 28, 2020, 2:05 am

Hi,

I have a cluster which has three nodes.

Two SAN volumes (from IBM SVC) are mapping to the cluster nodes.

One is for the quorum, and the other is for CSV.

After adding this volume for CSV usage as an available storage,

this volume can be moved whether using draining the host which owns the volume or moving the volume manually,

so as the quorum volume.

However, after adding the volume as a CSV, I could not move the volume either using draining the host or moving manually.

At the meantime, if the quorum is owned by the server which just is drained, the quorum moves to another node immediately.

But the CSV will show "online pending" and wait for timeout and show as failed.

After looking into the error log, it seems that the original node owner do not release the volume after the moving command is triggered, so the new node owner could not take over the volume successfully.

The new node owner also shows the error "ReleaseDiskPRFailure".

I've tried to validate the cluster without any error.

Do you know any possibilities that CSV cannot be moved properly?

Thanks.

Hello Experts,

We have three nodes Hyper-V 2016 cluster.

While Adding new Node to existing cluster , We did not run full validation wizard and missed other validations like network and storage.

Now when we try to run the adding new node wizard again, it is not showing to run the Validation Wizard instead it directly ask to add Node to Cluster.

Please see the screen shot below. I have tried from different Node also but the same I can not see validation checks.

Please help how can I come back that validation wizard  before adding the new node.

Hyper-V cluster 2012R2 to 2019? Possible?

Hi everybody,

I have a 3 node hyper-V cluster windows server 2012R2.

I wonder what is the optimal Hyper-V cluster migration path from Windows server 2012R2 to 2019?
Is this possible and supported to go directly from 2012R2 to 2019? or should I switch to 2016 Server and later to 2019 Server?
I would like to use mixed-OS-Mode.

Any help would be appreciated :)

Bluescreen on Windows Server 2019 Datacenter with Failovercluster 0x0000009e

Hello.

We have 2 Lenovo SR650 Server with Windows Server 2019 Datacenter and Storage Spaces Direkt.
The failover cluster role is installed and running.

Problem:

Sporadically the server which helds the active role (fileserver) of the cluster gets a bluescreen with error code 0x0000009e.
In event logs there is an entry:

Source: Bugcheck
The computer restarted unexpectedly. The errorcode was 0x0000009e (0xffffc1036f16a080, 0x00000000000004b0, 0x0000000000000065, 0x0000000000000000). 

I have a memory dump

And here is a strange thing, that i can not explain me.

The bluescreen occurs allways between 7:49 and 7:51 AM.

We updated all drivers, check the scheduled tasks for that time, googled for hours, but dont find any solution.

Microsoft has articles about this error code in failover cluster, but never on server 2019/2016. allways on 2008 R2.
This was fixed with a update years ago.

Some suggestions?

Thanks
Daniel

Max node failures in S2D

Hi,

Just wanted to double check something - the 3 failures applies to even greater than 4 node clusters, i.e. even all the way up to 16?

Thanks

Examples where everything goes offline

Over its lifetime, Storage Spaces can tolerate any number of failures, because it restores to full resiliency after each one, given sufficient time. However, at most two fault domains can safely be affected by failures at any given moment. The following are therefore examples of what three-way mirroring and/or dual parity cannot tolerate.

  • 7. Drives lost in three or more servers at once
  • 8. Three or more servers lost at once

Disks from other cluster node visible when using get-disk on Windows Server 2016

August 1, 2018, 5:07 am

Hello

For quite som time now, I have been trying to figure out why disks on other cluster nodes are listed when running Get-Disk (PowerShell) on Windows Server 2016 based cluster (15 node Exchange 2016 DAG).

No shared disks in the cluster (no fibre channel or iSCSI). Server "hardware" is VM-ware ESX and each server have their own disks.

The "remote" disks doesn't have a disk number as the local does.

We have a similar Windows Server 2012 (R1) / Exchange 2013 based cluster where this doesn't happen. And even though we have twice the disk count on these, Get-Disk and other disk related cmdLets are performing much faster.

I suspect that new Win 2016 feature is affecting performance very much. So I would like to disable it, if possible.

Does anyone know if that is doable?

Could UseClientAccessNetworksForSharedVolumes cluster setting have something to do with it?. It's 0 on our Windows 2012 cluster and 2 on our Windows 2016 cluster.

Thanks :)

NLB configuration problem

June 11, 2018, 7:15 pm

I am setting up an NLB cluster on the network and are experiencing the following issue.

This a 2 hosts cluster setup. Both servers are running Windows 2016. Each node has 2 NICs attached.

I enabled NLB on the first node and created the NLB cluster using unicast. The configuration was error free. However, once the cluster was configured (without adding the 2nd node to it yet), the node lost its network connection. I checked the IP configuration and did see that the cluster VIP is added to the NIC. The other issue is I didn't see the virtual MAC address (starts with 02:BF) assigned to the NIC. I can only see the original MAC for the NIC and NLB interfaces.

The status of the cluster is converged. No obvious error from NLB in event viewer.

I could not add the 2nd node to the cluster based on the issues above. Any idea?

Thanks

Rename a CSV volume in the NTFS level

Hi , we have a Windows Server 2012R2 Failover Cluster with HyperV, we have multiple SAN backed CSV volumes that are already created as Storage volumes. 

we noticed that some of these volumes are simply called "New volume" in the Disk management

the Disks are originating from DELL storage Luns and are mapped to both servers in the cluster using Fiberchannel HBAs and have multipathing 

i was wondering if i can simply go to the owner node of this Disk and open Disk-management and simply rename the NTFS volume or will it create issues with the mapped volumes or the cluster disks? 

if it would create issues  , please help to share the safe way to do this 

thanks

2-Node Stretch Cluster with Storage Replica?

I want to create a 2-node stretch cluster with Storage Replica.  I was able to setup the replica but once I create the cluster it breaks the storage replica.  I'm not sure if that is by design or not.  Is there something I am missing that prevents this type of scenario?  If I create the cluster first it does not allow me to create the replica with an error that it cannot find the volume on the source server that it must be a CSV on the cluster or added to a role on the cluster.  Neither of those are possible without the Replica running between the cluster nodes.

Hi,

I am receiving the below error when trying to add a new FileServer role in a Failover cluster, note that there are 3 existing running roles in the cluster, and create computer object permission is allowed in the OU where the failover cluster computer object resides.

This is weird

Event ID: 1194 Cluster network name resource '' failed to create its associated computer object in domain ' during: Resource online.

Appreciate your support
