After dbstore2002 has been added more than one instance (x1 and s2) - complete it with as many instances as possible using GTID (probably 7 will not fit, but we could have 4 or 5), and start using GTID on them.
This will validate the multi-instance beyond just 2 hosts.
Also delete the multi-source main instance it still holds.

Mentioned in SAL (#wikimedia-operations) [2017-07-21T17:02:27Z] <jynus> now that db2072 is compressed and fixed, stop it to finally clone it to dbstore2002 T171321

Once all the possible shards that fit in this host are done, we better copy them to dbstore2001 as part of: T168409 - see this for context: T168354#3464488

We will see which 2 would fit together

As we spoke, probably it is a good idea to leave dbstore2002 with the current 5 shards, so it has room to grow and we'd not have to revisit it in the next 6 months :-)

So I believe we can consider this resolved?
