Good News...
With last active Xpenoboot 5.2.5592.2 on 2 different Pc (Old Dell 745) with 1 disk 200Gb,2Gb ram and 2 network interface (one integrated ad one Intel pro100 desktop adapter), the process of creating cluster terminated correctly!!...
I notice that the network adapter added is essential for completing the process.. With normal oem adapter the process gave error durig first phase...
The configuration is really simple...
Create 2 usb key from img file for xpenoboot, modify on second key the cfg file changing the serial number (last digit is 3 i changed to 5)..
Install normally the synology system on either systems..
On the first network adapter configure a static ip address... The second adapter (for the heartbeat) on dhcp...
Connect directly the second adapter (the heartbeat) of either systems with a crossover cable (do not pass throught switch because the process change the MTU value to 9000)...
Create a volume on every system with standard mode (Synology raid mode SR isn't supported), in my case i have only one disk without raid protection.
Launch HA procedure adding the second ip, user and password.. The process terminated succesfully...
I notice that the slot disk marked as occupied is this case (with this Dell PC) is the number1.. But on other hardware where i try to install xpenology is the number3.. MAybe this difference can be important for terminating correctly the procedure...
Bye.
