Hi, I Have problem with Windows Server 2012, after remove Mount Point Disk.
The resources are gone from Cluster Role and now in OwnerGroup Available Storage.
I need to bring the resources back to Cluster role and put in the OwnerGroup SQL Server ?
This command is correct?

Hello Members,
OS: Windows 2016 Server Std
I got into a strange issue on the Windows cluster 2-node setup.
On one of the node. If the iSCSI initiator service is running and conected, it would hang diskmgmt, vssadmin list writers, chkdsk.,
if i make the Microsoft Iscsi service disabled and rebooted , things would work normally again with diskmgmg, vss,etc until i start the iscsi initiator service.
I am looking for some help to clear iscsi configuration or to start from scratch on iscsi part. suspecting some ghost/persistent drives may be causing this.
What has been tried.
uninstall/reinstall drivers from devmgmt.
updated OS patches to latest.
evicted and added the node back.
ran the validation tests -> successful.
Thank you
Venu
Hello Team,
I have 3 node cluster.
One of nodes in 2008r2 cluster is datacenter rest 2 are enterprise.
I am seeing below error.
Help me to correct this.
Log Name: System
Source: Microsoft-Windows-FailoverClustering
Date: XX
Event ID: 1548
Task Category: Node Mgr
Level: Warning
Keywords:
User: SYSTEM
Computer: XX
Description:
Node 'Node 1' established a communication session with node 'Node 2' and detected that it is running a different but compatible version of the cluster service software. It is recommended that the same version of the cluster service software be installed on
all nodes in the cluster.
Hi, so we are having an audit for SOC 2 certification. One of the requirements is that data at rest is encrypted. All the data evolved (that needs to be encrypted), is in a SQL Server web version database, on a virtual machine, in a Windows Hyper-V Cluster, on a Dell SCv2020 storage array. I been looking at ways to meet this requirement. Encryption isn't available on SQL Server Web version, our backup software - Veeam has issues with Hyper-V Encryption Support/Shielding, not sure if BitLocker is a good idea - maybe, and the storage array doesn't seem to have an "encryption" option although I wonder if RAID can be considered encryption as it uses algorithms and removing a disk makes the disk useless (I think I would need some professional reference if I try to make that case). This is only to check the block for data at rest being encrypted. The data is just as secure with or without this encryption.
Does anyone have any ideas that might be of help?
Thanks,
Ken
Teniendo un esquema basico de 2 servidores SQL en cluster y otro servidor con rol iSCSI target para disco Quorum y datos de las bases, necesito minimizar los puntos de fallas, por un lado la parte de SQL esta en alta disponibilidad con esto, pero el problema es si se cae el servidor iSCSI que muestra los discos, que se puede hacer para evitar esto? Hay alguna especie de cluster para 2 servidores iSCSI, y en caso que falle alguno el otro siga mostrando los discos sin que se caiga todo?
Muchas gracias

machine: windows server 2016
domain : all node in the same domain,the AD controller is work well
When I create the WSFC cluster, with all nodes WSFC installed already.
and added the domain admin user to the local administrator group.
I got the error when I add the node
the content is :
can't detect "EMSDB.ems.com" have installed the cluster feature!
can anybody help me ?
I already exclude the following:
1. firewall
2. with Server,Remote Registry ,TCP/IP NetBIOS running
The two nodes of a 2012 R2 Cluster lost communication. The System event log showserror 55 with hundreds of entries back to Nov 2019 and a single error 1230 at the time of the outage. I am comfortable with what happened and how we recovered from it. I have been tasked the Root Cause analysis report and it asks 'why' and 'lessons learned' to prevent repeating the failure in the future incidents.
Please advise.
We have a 2012 VM Cluster farm that consists of 5 nodes and 8 CSVs. One of the CSVs that has a size of 6TB is reporting a different disk usage.
When I open a Windows Explorer on the corresponding volume, select all folders, right click and choose properties, Windows counts the contents and reports a total usage of 3.9TB.
However, when viewing the same storage from Failover Cluster Manager, the total usage is 5.4TB.
Does anyone know what's happening? This difference causes us miscalculate the usage.
Thanks and regards,

Hi
Please help us on what are the solution on our issue. Current cluster is down and unable to up.
Step taken and basic troubleshooting :
1. Stop/disabled “Cluster Services “ in services and reboot the problematic host “VDI node”. Then we enabled and restarted the services. – Still unable to up the node VDI node " in the cluster.
2. Validate the cluster configuration of host in the failover cluster manager. –
Error found saying that :
A. This because the witness was not accessible. Please ensure that the witness resource is online and available.
B. Failed to join the cluster because it could not communicate over the network with any other node in the cluster. Verify network connectivity and configuration of any network firewalls.
C. Suspected an issue with communication on UDP port 3343.
3. Pinging vice versa the IP’s from node “VDI node1 to VDI node2” . – Pingable on both host. See the actual current status below.
4. Gathered both logs from “cluster event Logs and event viewer”
Thanks

We have 3 Node S2D Cluster using Iwarp and QL41262 25GB NIC's.
When I run Get-NetAdapterRdma on any node I get that RDMA is enabled.

Same issue on 2 separate clusters (both have 2x Server 2016 nodes) after cluster aware update (which only done first node!) As it failed the second node never updated & that is why it still works!
Both have failed cluster:
Node '' failed to form a cluster. This was because the witness was not accessible. Please ensure that the witness resource is online and available.
Cluster node '' failed to join the cluster because it could not communicate over the network with any other node in the cluster. Verify network connectivity and configuration of any network firewalls.
There is nothing wrong with witness disk, it is accessible fine, shows in Disk Management as Reserved (exactly as it should)
There are known issues with this update, but none states that it would kill Cluster!
Hello,
We are receiving an error saying "An unexpected error is keeping you from renaming the folder. If you continue to receive this error, you can use the error code to search for help with this problem. Error 0X80070542: Either a required impersonation level was not provided, or the provided impersonation level is invalid. The error occurs when attempting to rename the folder or file in the Volume folder. However, this only occurs on one of the nodes, depending on which node is the owner.
We experienced this with 2 of our customers. However, one of the customers upgraded the OS from 2012 R2 to 2016, therefore, the error did not occur again.
I am trying to build a 2 node cluster however it hangs on 'Forming Cluster' in the wizard. If I try via the cluster.exe command, it gets to '52% Forming Cluster' then errors with 1460 which I believe is a time out. The two nodes are VM's on HyperV 2012 R2. I have about 4 other 2 node clusters working successfully. I have also created this one successfully once, however we had to implement IPSec for communications to other subnets. Both nodes are in the same subnet however. Once the IPSec was enabled, the cluster failed. Since then, the VM's have been completely rebuilt but still unable to form cluster. Possibly an AD issue? Permissions seem fine, cluster object gets create fine. Here is the end of the cluster log. Thanks for any ideas!!
Hello,
I recently stood up 2 new host servers in my Hyper-V cluster. Whenever I use Failover Cluster Manager to add disks I've allocated from my SAN, the Add Disk option picks up 4 local disks (from my 2 new hosts) as available storage to add. Now I can just uncheck
the boxes and add my SAN space, however, I'd like to remove those as options.
If this helps, the 4 disks are again, across 2 hosts. So 1 SSD drive from each host and 1 RAID 6 2TB Drive from each host.
I can provide more information if needed. Any help with this would be great.
Thanks!
I'm running Server 2016 fully patched in a 5 node cluster. Hyper-V and S2D for a hyper-converged solution running a few hundred VMs. Two days ago one of my nodes decided that it wanted to be cranky. This caused the roles to rearrange on the systems and ended up putting one of my healthy nodes in the "Isolated" state. <g class="gr_ gr_456 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins replaceWithoutSep" data-gr-id="456" id="456">Root</g> cause for the other node that went out to lunch is still unknown and is being researched separately. However, this other healthy node has been stuck in an online but isolated state. See screenshot. I've seen plenty of examples where the node is offline and isolated, typically a network problem(network looks line. I have three separate NICs with separate switches/<g class="gr_ gr_3558 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling" data-gr-id="3558" id="3558">vlans</g>/IP space). I can live migrate VMs, my S2D storage is fully healthy on the cluster. No issues using this node, but I don't like the "isolated" state. I ran the cluster validation test for networking and it returns healthy. No warnings or errors in the validation test. Event logs show that the node when isolated, but in the same second I have a follow-up event that it's no longer isolated. These events exist on all nodes in the cluster, so there is no reason why it should be isolated. I'm sure if I rebooted this node(or even restarted the cluster service) that it would come back online as healthy, but another node in the cluster is having hardware issues, so that's not an option at the moment. Any thoughts would be appreciated on how to remove the isolated state. The end of the <g class="gr_ gr_5208 gr-alert gr_spell gr_inline_cards gr_run_anim ContextualSpelling ins-del multiReplace" data-gr-id="5208" id="5208">powershell</g> command shows it all. <g class="gr_ gr_5545 gr-alert gr_gramm gr_inline_cards gr_run_anim Grammar only-ins doubleReplace replaceWithoutSep" data-gr-id="5545" id="5545">State</g> is Up.

Hi,
One of our Windows 2012 Hyper-V Cluster nodes went down and we reinstalled the windows 2019 on it. Is it possible to recreate the cluster with Windows 2019 and Windows 2012 or must be same OS?
What is the proper way to recreate it?
Thanks.
I have just finished updating our cluster nodes from Windows server 2016 to 2019.
On 2 of our clusters there were no issues, but on a 3rd I am having the following issue.
When O go to update the functional level, I get this.
Update-ClusterFunctionalLevel : You do not have administrative privileges on the cluster.
I am a domain admin, in the local admins group on each node, and have full cluster access.
I can run any other administrative powershell cluster command without issue, and can fully admin via the GUI, but running the command Update-ClusterFunctionalLevel gives the no privileges error.
If I ask my other admin to run it, he gets the same.
If I create a net new AD account, assign it local admin on each node, and grant-cluster access full , that account also get it.
I opened a MS support ticket, but after 10 days I have still yet to get a call back. I even called back in (Sev-B = 4 hours...) and they said, yes I am still in the queue - wth....)
Anyway, I am assuming it is likely a bad registry entry, or something messed up on an AD object perhaps, but not sure where to look.
Hi,
I have a Hyper-V cluster and use SCVMM to manage the VMs. Whenever I delete a VM from SCVMM I get an error logged:
-------------------------------------------------------------------------------------------
Event ID: 1069
Source: FailoverClustering
Task Category: Resource Control Manager
Cluster resource 'SCVMM <vm name> Configuration' of type 'Virtual Machine Configuration' in clustered role 'SCVMM <vm name> Resources' failed.
Based on the failure policies for the resource and role, the cluster service may try to bring the resource online on this node or move the group to another node of the cluster and then restart it. Check the resource and group state using Failover Cluster Manager or the Get-ClusterResource Windows PowerShell cmdlet.
-------------------------------------------------------------------------------------------
It does not seem to cause any issues but I may be wrong.
Does anybody know why these errors may be generated when deleting a VM? Is it normal as I understand this event is a generic event.
Kind regards
