Configure High Availability role for generic service Docker for Windows

Need to be configured HA to N (around 20) number of Linux Containers running on windows server 2016 with docker for windows service.

is this can be possible with a failover cluster setup.

if it's possible how I can access my containers? is with client access IP and port ? or any deferent way?

I have done the HA setup followed steps:

  •  configure the 2 node hs cluster with witness 
  • added Failover cluster role > generic service > Docker for Windows (added registry root key for replication )
  • try to access containers with the failover cluster role client access name and IP but it's failing

* An error occurred while creating the cluster and the nodes will be cleaned up. Please wait...

An error occurred creating cluster 'test'.

The format of the specified computer name is invalid
* To troubleshoot cluster creation problems, run the Validate a Configuration wizard on the servers you want to cluster.

I'm trying to create a failover cluster in windows-2016 server, I have recently created a domain controller. I'm not sure whether it is because of the DNC or something.

S2D Cluster without RDMA - Network design questions

October 19, 2018, 7:18 am

Hi all S2D-wizards!

Let me describe what I'm trying to achieve before asking my actual questions:
4-Node Hyperconverged Hyper-V S2D Cluster based on Server 2019 Datacenter.
(Yes, I'm aware of the blocking right now when creating S2D-cluster on 2019 GA but I guess that's another discussion)
(And yes again, I've already purchased the 2019 Datacenter-licenses for this purpose...)

In each node:

  • 2x10G Mellanox Connect X3 SFP+
  • 4x10G Intel X710 SFP+
  • 2xNon-RDMA 10G Switches dedicated for storage network.
    Switches will have a 40GB Trunk between.
    Switches can do virtual stacking.
  • 2x10G Switches for VM-traffic and node-management.
    Non-RDMA - Non-stackable. Pretty basic 10G switches

My idea, which at least looks good on paper in my mind, is to create a simple team for failover on the Mellanox-ports for VM-traffic and node-management.
What would be the most suitable TEAM-type for this? SET or plain old switch independent LBFO?

I've spent the last couple of days trying to figure out how to design/create the storage-network.
There's plenty of guides available on how to configure RDMA-enabled networks but not that much for non-RDMA.
(Reason for not using RoCE is that switches are not compatible and reason for not using iWarp is NIC's are not compatible.)

Most documentation refers to creating a SET-team for storage-network and putting two different network-adapters for SMB behind the SET-team.
Why two nets for the SMB traffic? (SMB Direct?)
Does using a SET-team even make any sense when not utilizing RDMA anyway?

Is there any point in having a separate Live Migration network, if so would you put it on the management-switches or the storage-switches?

Then we the topic of bandwidth-aggregation and fail-over.
When deciding on this design, I was hoping to be able to aggregate the 4-port Intel NIC (used for S2D-cluster storage) over the stacked switches, thus creating an aggregated link of 40Gbps.
I realize this may be a configuration nightmare on the server-side so I'm ready to accept that I may have to ditch the stacking.. However i should be able to achieve 20Gbps? All four NICS connected in an active-passive fashion.
Am I dreaming here or do you agree this SHOULD be possible? If so, what kind of teaming would you recommend? Will S2D traffic be dynamically balanced across all physical nics?

Can anyone please help shed some light over my S2D-project?
Any input is greatly appreciated!

Best regards _Hallberg!

2-node switch-less cluster (S2D)

October 19, 2018, 7:31 am

Hi,

This is what we currently have NIC wise:

2x 1Gb NIC (teamed) in each node for management
4x 1Gb NIC (teamed) in each node for live migration traffic
2x 10Gb NIC (teamed) in each node CSV traffic

Currently the 10Gb NICs are throttled to 1Gb and connected to 1Gb switches. Our replacement switches are 24x or 48x 1Gb ports and 4x 10Gb ports (2x ethernet and 2x SFP+). We will use the SFP+ for the stack and were going to use the 10GbE ports for connectivity to the nodes for CSV.

Is there any reason to use a switch for this 2-node cluster? Instead can I just directly connect the NICs for both CSV and Live Migration? Is that a supported environment?

Thanks

Hi all. I have a multisite 4 nodes failover cluster with Fileshare witness. each site has two nodes, site Prod and site DR.

in windows server 2016 , further set preferred site to site Prod.

I would like to know the outcome if crosssite link is down:

1. Services Active node on Prod site and FSW owned in prod site

2. Services Active node on Prod site and FSW owned in DR site

3. Services Active node on DR site and FSW owned in Prod site

4. Services Active node on DR site and FSW owned in DR site

Running PowerShell scripts as domain accounts through Clustered Scheduled Tasks

Does anyone know if this is possible?

I can securely store the credentials by encrypting them with a certificate (in the machine store) and decrypting them inside a script running as system but I cannot successfully start another process using those credentials when it is inside a clustered scheduled task.

If anyone has pulled this off I would appreciate some pointers.

Windows Server 2016 Cluster Nodes are missing the site attribute

Hi,

I have a Windows Server 2016 cluster in which the cluster nodes are missing the "site" attribute. I know that this is a new 2016 feature and that my cluster is a upgrade from 2012-R2 but the cluster functional level was raised to 9 (2016). What else should I do to be able to use the site awareness feature?

When I try to set site awareness, I get:

PS C:\>  (Get-ClusterNode MyClusterNode1).site=1
The property 'site' cannot be found on this object. Verify that the property exists and can be set.

When I try to see the properties of a clusternode, I get no "site":

PS C:\> Get-ClusterNode | Get-Member s*

Name              MemberType Definition

Migrating HyperV 2012 R2 Cluster to a new domain

Hello everyone,

I need to join a 3 nodes HyperV 2012 R2 cluster to a new domain. I have searched doc in the MS knowledge base but I didn't find anything. I would like to understand if there's a way to join the cluster to a new (trusted) AD domain without destroying and recreating the cluster. Apparently, there's no official MS article on that

Regards,

Hal

I have a SQL Server Cluster Availability Group, and the cluster is configured to use a file witness.

recently I expand the cluster to my DR site and I get a subscription from Azure to host the witnesssite

I want to change the cluster witness from a local file witness to use the cloud witness, but the problem is the option is disabled.

How can I change the Witness, and why its disabled.

Removing and Adding Hyper-V node to cluster

Guys,

have unique requirement of making few hyper-v hosts as a cold standaby host which can be bring back to life if needed such as another node has died.

How practical is to remove a node from cluster, shut it down, when needed start the hosts, readd to domain and add back to cluster? 

Or just shut it down and start every 30 days to keep it intact in the domain?

Have 5 nodes cluster right now and have enough resource to run all the workload even if one of the node is down (apart from the one I want to keep as cold standby)

MS 2012 R2, MS failover cluster issue while creating a MSMQ role

Cluster resource 'dc1bsimsmq' of type 'Network Name' in clustered role 'dc1bsimsmq' 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.

Cluster network name resource 'dc1bsimsmq' failed to create its associated computer object in domain 'gst.gov.in' during: Resource online.

The text for the associated error code is: Access is denied.


Please work with your domain administrator to ensure that:
- The cluster identity 'DC1BSIAPP$' has Create Computer Objects permissions. By default all computer objects are created in the same container as the cluster identity 'DC1BSIAPP$'.
- The quota for computer objects has not been reached.
- If there is an existing computer object, verify the Cluster Identity 'DC1BSIAPP$' has 'Full Control' permission to that computer object using the Active Directory Users and Computers tool.
