I just set up a new NAS at home and created a few volumes on it, along with enabling access to those volumes (i.e. enabling the Mac File Service on the NAS), and creating an account for myself.
On the iMac, I went into Finder and provided credentials and stored them in my keychain. No problem - I can see and access the NAS volumes.
I then went into System Preferences, Users & Groups, and added those volumes to my Login Items so that they'd be mounted automatically when I log in. I did this with my previous network storage (a Windows Home Server) and it worked fine.
However, in this case, I'm seeing the volume I want mounted at login get mounted TWICE... the "Home" volume, which is unique to my account on the NAS, gets mounted twice and appears twice both on the Desktop as well as in Finder when I click on the NAS' name in the sidebar.
Why would a volume get mounted twice like that? Is there some other place I should be looking to find the duplicate mount setting?
