Hi guys,
Yesterday, I detached one of my relevant databases to perform some disk related task. When I tried to attach it again I got well known message
Cannot use file 'd:\xxxx_data.mdf' for clustered server. Only formatted files on which the cluster resource of the server has a dependency can be used.
Server has been running for couple of months without stop and nobody has been aware that d: drive is not in SQL Server resource dependency.
Do you know a way to attach\create database on a disk which is not SQL Server dependency but it is in a cluster group? Any help appreciated.
Cheers,
Bartek

There is a reason for the dependency of sqlserver instances vs drives !

Why are you tempted to avoid this dependency ?

Can't be done. When running in a cluster all drives that SQL uses have to be dependencies of the SQL service. This is to ensure that the drives are owned by the correct node after a failover and that the drive resources come online before the SQL resource does.

Hi ALZDBA

Believe me, I got burnt my fingers burnt few times with that message 🙂 so I know how SQL Server cluster should work. As I wrote, I discovered lack of drives in dependencies by accident. I'm sure you came across situation that everything had been working fine until you had to change something and then you saw a mess which should be clean up.

I asked you because I need this database running until evening, then I will have time to fix the SQL Server resource.

Regards,

You'll either have to fix the dependencies or move the DB files to a drive that's already a dependency.

Thank you for your responses.

I was looking for a hack but it seems I will have to wait till evening to fix dependencies. No drive is in the resource dependency :Whistling:
