Trying to verify that what I am seeing is intended behavior not something I have messed up. When installing 2017 or 2019 and selecting to have tempdb data files and tempdb log file on different drives than the install drive the files are first created on the install drive and then moved to the drive in the config file.
EXAMPLE:
The install appears to create the files on Z: first and try to grow them. Z: is not large enough to handle the growth so install fails. I would have expected the files to be placed on T and U first and then grow. Is this expected or am I missing something.
CONFIG FILE
INSTANCEDIR="Z:\Program Files\Microsoft SQL Server"
SQLTEMPDBDIR="T:\data"
SQLTEMPDBFILECOUNT="8"
SQLTEMPDBFILESIZE="37888"
SQLTEMPDBFILEGROWTH="1024"
SQLTEMPDBLOGDIR="U:\log"
SQLTEMPDBLOGFILESIZE="76800"
SQLTEMPDBLOGFILEGROWTH="1024"

Wow... seriously? The install fails due to an erroneous default behavior? Heh... and then you say "you need not worry"??? :blink: What is your work around for this problem?

Set up hundreds of instances on those version without any such problem, you may wan't to check your model db though!

No the z drive is 100gb drive but our tempdb is is close to 200 gb for data and 100 gb for log. Seems really dumb for MS to add this functionality in the install but not move the files first. I guess most people run small sql databases that are not very busy.

Curios how you have not seen this is the drive you install too that large? or your tempdb is normally pretty small?
