File system error: The background thread running lazy writer encountered an I/O error. Physical file: \\?\D:\OLAP_DATA\Project88.6.db\Dim Service Dim Std Sub Key.0.dim\677.Hierarchy 5.Subkey Only.lstore. Logical file: .
I believe a corruption of OLAP database occured during the dimension update processing and I don't know what might have caused and factors that have caused this problem.
The resolution to this error was to restart analysis service then process update the dimension.
