I joined Netapp earlier this year and I am responsible for maintaining and developing Harvest. Hopefully I will be also able to help you with any issues you encounter while using Harvest.
One of the things that I want to do in the coming weeks, is to install Harvest natively on different Operating Systems and see what the possible challenges are (and maybe write some guidelines). If you use Harvest natively (i.e. not in NAbox), could you please help me understand what OS are more commonly used and which of them are problematic?
