Storage : Pupose of the "Master" storage domain status

Hello

I've been all through the official documentation but can find no information regarding the purpose or definition for the "Master" storage domain.

Would you be able to provide this ?

Particular questions I have are :-

What is its purpose ?

Is it manager, datacentre or cluster specific ?

Can you have mutliple Masters ?

What decides which SD should be Master ?

Can the Master status be moved/migrated between SDs?

Thank You
