Some of the problems I had was I am using one of the newer cards and at the time the Driver that Open-E used would not allow the web tools to work from inside Open-E (this has now been fixed) on of the larger problems I have had is adding additional Volume Groups to Open-E. When I expand a volume group it works okay but if I make a new Disk set in Areca it does not show up, once I reboot it works. I tested with an older LSI card and had no problem.
