Hello Wesley, I couldn't find any tracker related to this and since min_size=1 has been involved in many critical situations with data loss, I created this one: https://tracker.ceph.com/issues/66641 Regards, Frédéric. ----- Le 17 Juin 24, à 19:14, Wesley Dillingham wes@wesdillingham.com a écrit :
Perhaps Ceph itself should also have a warning pop up (in "ceph -s", "ceph health detail" etc) when replica and min_size=1 or in an EC if min_size < k+1. Of course it could be muted but it would give an operator pause initially when setting that. I think a lot of people assume replica size=2 is safe enough. I imagine this must have been proposed before.
Respectfully,

Note to self: Change the docs and default to discourage this. This is rarely appropriate in production.
You had multiple overlapping drive failures?
