The link about maintenance mode does not apply to the free version. Is there a PowerShell or other command to put it into maintenance mode?
The link I shared describes what maintenance mode is and why enabling it might be needed. What I was trying to say is that Maintenance Mode is not intended to be enabled for a node restart. Please consider following the recommended restart procedure.
You can enable it with MaintenanceMode.ps1 from C:\Program Files\StarWind Software\StarWind\StarWindX\Samples\powershell
This last time I drained the roles and then shut down the StarWind service(s) before reboot and didn't have a full sync after the node came back online.
Please note the role drain is to be related to Failover Cluster, not StarWind VSAN.
Did you stop StarWindService on all or 2 nodes at a time?
Did you wait for fast synchronization to complete prior to reboot?
Finally, do you have a Write Back cache? If yes, did you flush it before restarting a node?
Let me know if you have more questions.
