Could not create tempdb. If space is low, extend the amount of space and restart.
This error occurs when there is not enough space on the device to create the tempdb database.
You can create a new device with at least 2 MB or free at least 2 MB on the device. If you create a new device, make sure it is specified as a default device, as in the following example:
sp_diskdefault new_device_name, defaulton
If no default device is specified, Microsoft® SQL Server™ sends an “out of memory” message (you can ignore this message) and then moves tempdb to RAM automatically.
