Hi guys
can anybody help me ????
I will be very grateful if anyone can help me
*Mr. Lars Ellenberg tell me that:*
"With special purpose built fencing handlers,
we may be able to fix your setup so it will freeze IO during the
disconnected period, reconnect, and replay pending buffers,
without any reset."
Note.- I believe that the problem is my NIC Realtek, as soon as I can i will
change it for Intel,
But for now i like to know how apply this change?,
And since I am not an experienced in DRBD, I wish someone would show me how
it should be finally the
global_common.conf or *.res configuration files.
*This is my actual configuration with DRBD 8.4.2 Version:*
*global_common.conf file:*
