HI,

We have a 2 node deployment which have been relocated recently and now they cant synchronise.

I get this error when I run the syncHAdeviceadvanced powershell script
200 Failed: synchronizer has invalid state..

I have updated to the latest version.

Can anyone help?

Welcome to StarWind Forum.
1. Install Management Console
2. Connect to the StarWind VSAN hosts/Control VMs.
See if any of the device mirrors are in sync.

Follow this guide https://knowledgebase.starwindsoftware. ... -blackout/ (mark a node as synchronized with the script).
You might have write back cache. Consider disabling it https://knowledgebase.starwindsoftware. ... -l1-cache/.

HI,

I have removed the caching as instructed but get the same error?

I assume the "SyncHADeviceAdvanced" script is the same as using the option in the management software?

You are right but please make sure to follow the guide carefully (i.e., mark ONE NODE while partner(s) is/are down).

Hi,

I have followed both instructions exactly, and it has made no difference.

Error when one has its starwind service disabled (I have *** out specific info):
Synchronize device *****

-
control 0x0000016A945F7DC0 -Synchronize: -SynchronizationType:"1"
-
200 Failed: can't find available or valid partner for synchronization..

Error after turning off caching etc:

You can induce the sync status manually.
1. Stop the service on both sides
2. Go to the node you would like to check first.
3. Go to the _HA.swdsk files.
4. locate the area for node id ="1" that looks like this

Code: Select all

<sync_status>1</sync_status>
It might be

Code: Select all

<sync_status>0</sync_status> 
in your case. Set it to 1.
The area should look like this

Code: Select all

<node id="1" name="HAImage" shut="false" active="true" flags="0">
    <storages>
      <storage_ref id="1"/>
    </storages>
    <parameters>
      <type>1</type>
      <priority>0</priority>
      <auto_sync>true</auto_sync>
      <sync_status>1</sync_status>
      <sync_delay>50</sync_delay>
      <sync_traffic_share>50</sync_traffic_share>
      <failover_conf>0</failover_conf>
      <last_sync_snap_id>0</last_sync_snap_id>
      <alua_access_state>0</alua_access_state>
      <maintenance_mode>false</maintenance_mode>
    </parameters>
5. Start the node where you made the changes.
6. See if the storage is synchronized in Management Console.
7. Check the data.

Hi,

I hade this:
<node id="1" name="HAImage" shut="true" active="true" flags="0">

So I updated it to the same as yours...

What about the node 2 section should this be the same?

Node 2 had the <sync_status>0</sync_status> so I changed it to 1, its now synchronising,
