Hello, We have setup ctdb+Samba v 4.11.1 and testing with Windows client and failover works mostly ok. However when using regular Windows file copy, the copy operation is interrupted during ip takeover. Is there any solution to make the failover transparent to Windows file copy ? I understand that SMB2 durable handles should not be used in a clustered setup, and SMB3 persistent handles + witness are not support yet, is this correct ? Any help/pointers will be greatly appreciated. /Maged

My understanding is that it should reconnect and continue after clustered Samba style failover. When you say "Windows file copy" do you mean drag-and-drop in the file manager? I would have thought this would reconnect too...> I understand that SMB2 durable handles should not be used in a clustered > setup, and SMB3 persistent handles + witness are not support yet, is > this correct ?I believe those statement are true. peace & happiness, martin
Hi Martin, Yes xcopy /z? does work. I am referring to the File Explorer / ui copy ..such as you drag and drop a file. It either it does not like network reset / ctdb-tickle very well or maybe it is has too small a timeout for for ctdb transfer.
