We had massively nodes blocking on starting up status.
This was supposed to be fixed into 7.1, so i made the upgrade, but didn’t change anything.
In fact we had huge network configuration problems, especially in our storage system.
We fixed this and this reveal what’s looks like a problem in 7.1 with MongoDB.
We upgrad our repository to 10 Gb/s (virtually) and the trafic is pretty intense & capped.
