Initial Full sync speed

[sls]

Is there a way to speed up the full sync process? When creating the HA target, the disk image files between nodes are taking forever to do the full sync. 2TB image takes 4 days to sync up is very slow. It doesn't seem like it's the network bottlenack because if you look at the network utilization in task manage, the network usage is only 10% or less on a gigabit interface. Copy a 2TB data file between two servers shouln't take more than 1 day.

Hi, we are currently working on this function. One of the upcoming versions will include soft shutdown of the HA cluster
I would also like to advice you the following:
Install the latest NIC drivers
enable 9k jumboframes on both NIC's (switch has to support jumboframes too)
if using OS older than 2008 than you also need to do few registry tweaks to improve the Network performance
Change the following TCP parameters in the registry (on all the machines involved in SAN usage and running OS older than 2008 server):
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
1) GlobalMaxTcpWindowSize = 0x01400000 (DWORD)
2) TcpWindowSize = 0x01400000 (DWORD)
3) Tcp1323Opts = 3 (DWORD)
4) SackOpts = 1 (DWORD)
c) Reboot.
(this info can also be found in StarWind embedded help section)

By the way: you do not need to sync the HA device if you are using new raw image files.

If I created the HA target with clear disk option, the target is showing exclaimation on both node. How can we create a HA target without full sync?

You should use "do not synchronize virtual disks" option instead.
If the error shows up than please ensure that both of your OS are 64 or 32 bit, please note that both StarWind boxes should be physical.
