Hi folks,

Yesterday (March 12, 2020) I had my first production issue using StarWind vSAN Free. I'm using vSAN servers (build 12767) on Hyper-V 2012 R2 FailoverCluster (2 storage and 3 computing servers separated)

All of sudden all my CSVs were paused, some VMs restarted and just one CSV have presented a Sync channel fail with a very bad iSCSI performance.

I could see this message several times on "events" tab of management console.
Code: Select all
command "WRITE" ... request response time is longer than expected. Response time is 10 sec.

I have three CSV's, and of course it wouldn't be a network issue, because the other two stayed perfectly normal.

Here is a piece of the log file, this part repeats many times since the first time it happened.

Code: Select all
3/11 23:25:26.934139 1458 Common: *** `anonymous-namespace'::iSCSIAsyncCommandCallback: User request 0000006F9A0EC9D0 has failed due to unidentified error.

Target: ''

I tried to restart the StarWind service on one of nodes.
First it refused to restart, stayed stuck on "stopping" status. So I had to disable all Sync and iSCSI network interfaces to finally get it stopped.
After the restart, it did a Fast Sync and all normal again. I moved my machines back to this CSV and everyhing is ok now.

If you guys wanted more detailed logs, please let me know.

Thank you Michael

Do I need to request a new license in order to upgrade from build 12767 to the latest one?

No, you do not need to request a new free key.
