Why unable to find the exact path for grains storage in master?

I am trying to completely remove the grains from the system. I have one master and one minion setup(minion id= minion1). I am doing


salt minion1 grains.ls

that is listing me all the grains

Now I removed data.p which is the cache memory for the grains in master

path : /var/cache/salt/master/minions/minion1/data.p

Without running a salt_sync or any other command for sync I am again doing.

`salt minion1 grains.ls`,

It's returning the same result.(The grains are still somewhere stored.

Where exactly it is storing the grains and how to delete that?

These are built-in grains, which are collected at minion startup. Here's the code responsible for generating them.

You cannot remove them, but you can overwrite them, for example to an empty value in /etc/salt/grains:

osfinger: null

or with grains execution module: salt minion1 grains.delval osfinger.

Keep in mind that some of the core grains are essential for the correct functioning of salt, e.g. module providers for pkg module rely on them.
