Moving TempDB Production - rebuild space

    Hi,

    I ran out of space while rebuilding indexes over the weekend.

    I'm thinking of adding additional space (additional Lun) and then moving my tempdb over to this new space. The thought is that I can have the index rebuild use tempdb so I won't run out of room during the rebuild.

    1) Is this is a good plan?

    2) If so, can I move tempdb on a busy production server without stopping services?

    1) So you are currently using 'SORT_IN_TEMPDB = ON'? - if yes, additional storage for TEMPDB will work.

    2) TEMPDB move will require an outage.

    Are you absolutely positive that it was TempDB that you ran out of space on? Even with sort in temp db turned on, most of the load will be in the MDF file and the LDF file.

    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
