Followup of T327001
To be done when dumps process finish to avoid overloading the production dbs (in approximately 24 hours).
If you want me to do it, just assign it to me!
It's a single command+wait so not much overhead, I prefer to mostly block it for now until backup finishes.
Sounds good, let me know if you need me :)
I "documented" how I did it in case it is useful and for sanity check:
All tables resulted ok from the check, comparing eqiad, its codfw primary and itself on the last 4million rows of all tables.
