Server 2016 - SMB Client/Connectivity EventID:30803 - Failed to establish a network connection

May 16, 2018, 6:01 am

Server 2016 Hyper-V hyperconverged cluster 2 nodes. No visible problems in any area.

Cluster use two VLANs/IP subnets for SMB traffic: SMB1 and SMB2

Every 12 seconds I have this event 4 times in Microsoft-Windows-SMBClient/Connectivity on both servers

Here is event from Server 1.

Failed to establish a network connection.
Error: {Device Timeout}
The specified I/O operation on %hs was not completed before the time-out period expired.
Server name: fe80::311b:c8d3:c747:6872%14 - THIS IS FIRST SERVER MS Failover Cluster Virtual adapter
Server address: [fd74:24b5:ff8d:19:172:16:1:2]:445 - THIS IS SECOND SERVER "SMB1" VLAN/SUBNET
Connection type: Wsk
Guidance:
This indicates a problem with the underlying network or transport, such as with TCP/IP, and not with SMB. A firewall that blocks TCP port 445, or TCP port 5445 when using an iWARP RDMA adapter, can also cause this issue.

IS THIS ANOTHER FAKE ALARM WHAT NOBODY CARES TO FIX???

FRS Replication Errors 13552 & 13555

I have 1 Forest and 2 Sites. Site 1 has 3 DC's DC1,2,3. Site 2 has 2 DC's 4,5. DC1 is the FMSO Master (all 5 roles).

All DC's Replicate. I use DC1 as my primary to change GPO's. I noticed that the other DC's are Not getting the changes (DC1 is up to date). I'm getting 13552 & 13555 errors. My research leads me to a NON-Authoritative Restore. Do you think this is Ok?More important...DC4 & 5 in the other Site may have their own GPO updated. I have never done a NON-Authoritative Restore. I need All DC's the same, but I don't want to wipe-out DC4 & 5 because they may have updates that I don't know about. Is a NON-Authoritative Restore done 1 DC at a time, so I can do DC2 & 3 and not touch DC4 & 5 for now???

Monitor a Windows 2016 Work Folder server to ensure that all Work Folder clients are successfully synchronising

Hello Guru's

We have a very large Enterprise Customer who uses Work folders.

We need to know how we can remotely monitor a Windows 2016 Work Folder server to ensure that all Work Folder clients are successfully synchronising. We have come across a technical article from Microsoft that states a Windows 2016 Work Folders server no longer supports the 'last successful sync' stamp for a user. We have had a case with our customer whereby a user had 70GB of data in their local client Work Folder folder but the data was not synching back to the On Premises server. Had the user lost or had a technical issue with their laptop then the user would have lost all their data. 

The statement from Microsoft below was made in the technical forum article below.

 Microsoft Statement - For Server 2016, we removed the LastAttemptedSync, LastSuccessfulSync and the SessionID info because it was not accurate


https://social.microsoft.com/Forums/azure/fr-FR/21be7c07-ca37-4d73-95b1-e437ff5a5bba/windows-2016-workfolders-monitoring?forum=winserverfiles

The main reason for asking the question above is that if the statement above from Microsoft is true then it would render any attempt to gather Work Folder client/server  sync information inaccurate.

Thanks in advance

DFSR cloning issues

Hi,

I'm trying to use DFSR cloning on a fairly large volume with about 2.5 million files. After following the procedure outlined in TechNet docs and the "attack of the clones" manual, I'm stuck with a weird issue - almost a million records are reported as non-matching after the cloned DB import. (As outlined in event ID 2418). This, of course, means that cloning turns out pretty useless.

At the same time, I've compared DFSR hashes of over 100 000 pre-seeded files, including the ones that are [consistently] moved into PreExisting after cloning [on every cloning attempt], with the original server and they 100% match. 

After this I've found that the  debug logs of import procedure weirdly report the cloned records as having 00000000-00000000-00000000-00000000 as their Hash and Similarity, resulting in  mismatches with the real files that, obviously, have non-zero hashes.

After that I've used an ESE database viewing tool to check the data inside the clone export DB, and it's the same in there - a lot of records in IDTable have zeroes in Hash and RdcSimilarity columns.

This is not a very complex configuration, although the cloned volume is a hub hosting four replicated folders, each with its own replication group, connected to two remote servers. Another factor may be or may be not that this cloned volume was once deduplicated some time ago, and then was unoptimized (hydrated) (both operations done long prior to cloning). All participating machines are 2012R2 with latest 2018-03 rollups installed.

So, what could be the issue here, and can anything be done?

VSS Snapshot failing on Remote SMB File Shares

Hi All,

I've got a SOFS cluster hosting UPD's (.vhdx) for RDS 2016 which I'm trying to backup and replicate using VSS and Robocopy, I've followed the steps in this KB but I'm getting an error message:

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-r2-and-2012/jj612865(v%3Dws.11)

The article specifically mentions the Hyper-V VSS Writer althought I'm not doing a hyper-v backup, i just want a basic snap of the share with the files inside.

When i try to take the snap i get this:

DISKSHADOW> Writer Verify {cd8285c9-8c5c-4d35-830e-e3caf6d61080}
DISKSHADOW> Set Context Persistent

ERROR: The writer "{cd8285c9-8c5c-4d35-830e-e3caf6d61080}" was not included. Aborting ...
       Check the syntax of the writer name and writer ID.

I've looked up the list of VSS writes on both the source and target machine and assume its the "ASR Writer" that I need to use, but that or any other writer from the list produces the same error as shown above.

I've installed the "FS-VSS-Agent" agent role on both source and destination machines, added my account to backup operators on both boxes and rebooted them.

We are using Windows Server 2008 R2 iSCSI initiator to connect to an iSCSI target on Sun Storage. On some servers iSCSI target shows connected but no volume appears in Disk Management or disk in Device Manager under Disk Drives. In iSCSI target properties under Devices it shows

Name: Disk -1

Address: Port 1: Bus 0: Target 0: LUN 0

I tried restarting iSCSI service, disconnecting and reconnecting all targets, restarting server without success.

Only action that allows target to show up properly under Disk Management is reinstalling Windows Server.

Any ideas how to troubleshoot this?

Server 2019 Cannot access admin shares in a workgroup

Hi,

I have tried to find the issue but this is so weird.  The servers here are all guests on Server 2019 Hyper-V and on the same virtual network and VLAN.  These servers are to be located in a DMZ.

I have 2 workgroup servers (Server 2019) that I built about 4 months ago and I can access the admin shares from each of them as the default local admim on both machines has the same password

Today I am trying to build 2 workgroup servers.  Stock standard build with one network card each.  Both servers have the same password for the default local admin account but when I try to access the admin share on each of them I get asked for a username and password.  It does not continue from there.  I get access denied and asked for username and password again.

I don't get this on the other 2 servers.  I have searched but cannot find anyone experiencing the same issue without using the registry hack they mention (which reduces the security a bit and these are DMZ servers so definitely don't want to do that)

thanks

Storage Spaces Direct (S2D) in a 3-node Switchless Topology

May 15, 2017, 8:34 pm

I was running a two node S2d cluster with crossovers on 10GbE cards (ConnectX-3 with RDMA), however I have now extended it to three nodes with three dual port cards in a ring topology. I did this to avoid having a DCB/PFC switch in a homelab environment.

This involves dual port cards, each server connected to each other (1<->2, 1<->3, 2<->3) over three subnets. Clearly this means each subnet only involves two of the hosts at a time.

Everything seems great both with Windows clustering and S2D except for one little warning:

> Get-StorageSubSystem *Cluster* | Debug-StorageSubSystem

Severity: Minor

Reason         : The server 'hv1' has missing network adapter(s) connected to cluster network 'Cluster Network 217'.
Recommendation : Connect the server to the missing cluster network.
Location       : Server 'hv1', LENOVO, ThinkServer TS140, XXX, Network Adapter connected to 'Cluster Network 217'
Description    : Network adapter connected to cluster network 'Cluster Network 217'

Reason         : The server 'hv2' has missing network adapter(s) connected to cluster network 'Cluster Network 216'.
Recommendation : Connect the server to the missing cluster network.
Location       : Server 'hv2', LENOVO, ThinkServer TS140, XXX, Network Adapter connected to 'Cluster Network 216'
Description    : Network adapter connected to cluster network 'Cluster Network 216'

Reason         : The server 'hv3' has missing network adapter(s) connected to cluster network 'Cluster Network 215'.
Recommendation : Connect the server to the missing cluster network.
Location       : Server 'hv3', LENOVO, ThinkServer TS140, XXX, Network Adapter connected to 'Cluster Network 215'
Description    : Network adapter connected to cluster network 'Cluster Network 215'

It looks like these Minor severity warnings are non-impactful to the setup, just a warning that there is a non-identical configuration on each cluster node.

For a homelab environment, this shouldn't be impactful, correct? Safe to ignore I hope?

Storage Migration Service - Cut Over static IP issue?

November 4, 2019, 12:53 pm

Testing the new Storage Migration Service (ver.1.57.0) everything goes great until it gets to the point of migrating the server IP from source (Win2K8R2) to destination (Win2K19) server.

All required Firewall ports are open. Even verified all RPC ports


Job completes successfully if both servers have IPs from DHCP, and I check the check box for "Use DHCP" underneath Source network adapters. The cut over completes successfully, and logs say both servers are already using DHCP and no ip addresses are migrated or changed. 

Job fails if I choose to statically assign the IP address for the "Source Network Adapter", and keeping the "Destination network adapter" as DHCP. It fails everytime on trying to assign the static IP on the "Source Network Adapter"

Logs basically show it tried to set the IP and it failed with eventually losing network connectivity to the server, which in turn is why I see WINRM error messages in the logs. Different things I notice of why it loses network connectivity. Sometimes I see it lost its domain trust relationship. Other times when it tries to migrate the IP the DNS entry is removed from the DNS server forward lookup zone , which in turn the Storage Migration Service orchestrator server cannot talk to the Source server.

Anybody else experiencing this issue, or might know why this is happening?

Thank you,

Chad

Cannot read file contents in vhdx file

November 6, 2019, 1:30 am

I have a windows 2016 server.  It has drive C: which is on a physical disk and drive D: which is in the storage pool.  Recently I used disk2vhd to backup the drives to two files on a mobile disk, C.VHDX and D.VHDX respectively. I detached the original D: and attached D.VHDX as new D: and copy some files from new D: to the mobile disk, everything seems OK. Then I moved the mobile disk to another computer which runs Windows 10 and attached D.VHDX, I can see the files and directories, but if I tried to copy the file, I got "error 0x80070780: The file cannot be accessed by the system". Actually I can copy small files like several K bytes, but if I copy file like 20 megabytes, it failed. The mobile disk has enough space so it's not the space reason. I tried to attach it to another computer with Windows 2016 Server through network, the same error occured. But I had no problem with C.VHDX. I guess it may because C.VHDX was from a physical disk but D.VHDX was from a storage pool.  

So the problem is I can only access the file contents of the vhdx file D.VHDX from the original computer but not any other computers. Anyone knows what caused the problem?
