Hello,
I've been trying to install SSAS (SQL Server 2012 with SP1) on Windows Server 2012. I'd like to place all the SSAS files on a separate volume so, in the setup, I changed all four data directory paths by replace C:\Program Files\Microsoft SQL Server with D:\ (leaving the rest of the path unchanged). When I do this, startup of the SSAS service fails with the message shown below.
The following system error occurred: Access is denied. File system error: Error occurred during the creation of directory: '\\?\D:\MSAS11.MULTIDIM\OLAP\Data'.
I don't think this should be relevant, but I this is a named instance install (the name is "MULTIDIM"). It is also the first instance install. There is no database engine instance.
I tried this first using an Managed Service Account for the Analysis Services service account. Then I tried using the default local virtual service account. Same result in both cases. Finally I gave up and installed (using the default local virtual service account) using the default data directories. it worked
