VSAN Free / Powershell / check sync state

Hi all,
I'm new to VSAN Free. I've setup a 2 node cluster using CreateHA(two nodes).ps1.
Got it working and connected to my vmware.
How can I check the sync state with powershell?
Tried to use parts of the script without any luck.
The $device object is created via Add-HDADevice, which is not working on an already created HADevice.
Get-Device with the IP of the first node fails with:
The property 'Connected' cannot be found on this object. Verify that the property exists.
The property 'Devices' cannot be found on this object. Verify that the property exists.
Any suggestion?
TIA

Hi denkteich
Did you try to run C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell\SyncHaDeviceAdvanced.ps1 ?
My result:
PS C:\Windows\system32> C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell\SyncHaDeviceAdvanced.ps1
HAImage1
Device synchronized

Hi Serhi,
maybe this is not what i wanted.
the script is alway displaying synchronized.
i did the following thing:
- shutdown node 1
- copied lots of data to node 2
- ran script: synchronized, even if node 1 is not available
- started node 1
- ran script: synchronized, even while node 1 is synching the changes
how can i get this like the replication status, if it is resyncing or how much percentage is done?
cheers

It looks like you are running the script against the current node's VSAN service.
To check whether a particular device is synchronized on all partner servers, you would need to adjust the script to check all of them.

This can be achieved by checking the HA device properties. Check the enumDeviceTarget.ps1 script for more details.

i ran it on every node.
same result -> synchronized, even while still syncing.

Try using enumDevicesTargets.ps1: syncStatus 1 would mean "synchronized', 2- synchronizing, 3 - not synchronized.
You can access that by checking the following property of the device:

Perfect, that was it I was looking for.
One more question:
how can I shorten it for only one device, not for all?

something like:
Code: Select all
if ($device.Name -eq "HAImageX") { # where "X" is the number for that particular device (like HAImage1)
$device.SyncState
}
should work for you.

My SyncState.ps1 is ready.
Here it is:
Code: Select all
Import-Module StarWindX
try
{
Enable-SWXLog
$servers = @()
$devicename = "HAImage1"
$servers += New-SWServer 10.0.0.181 3261 root starwind
$servers += New-SWServer 10.0.0.182 3261 root starwind
foreach($server in $servers)
{
$server.Connect()
write-host "Server:" $server.IP "-" $devicename -foreground yellow
foreach($device in $server.Devices)
{
if ($device.Name -eq $devicename) {
switch ($device.SyncStatus){
1 {$status = "synchronized"}
2 {$status = "synchronizing"}
3 {$status = "not synchronized"}
default {$status = "UNDEFINED"}
}
write-host "SyncStatus:" $status
write-host "SyncPercent:" $device.SyncPercent "%"
}
}
$server.Disconnect()
write-host "-----------"
}
}
catch
{
Write-Host $_ -foreground red
}
finally
{
}
