[Samba] ctdb failover interrupts Windows file copy

[Maged Mokhtar]

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.
