[one-users] could not open disk image : Permission denied

[Mario Giammarco]

I have just started a similar thread because I have the same error, but I
have already set correctly:

user  = "oneadmin"
 group = "oneadmin"
 dynamic_ownership = 0


Have you solved the problem?
What else can I try?

Thanks,
Mario
