When we ran our test cluster with size 2 I experienced a similar issue, but that was in Hammer. There I could find the corresponding PG data in the filesystem and copy it to the damaged PG. But now we also run Bluestore on Luminous, I don't know yet how to fix this kind of issue, maybe someone else can share some thoughts on this.

Hi.

We have size=3 min_size=2.

But this "upgrade" has been done during the weekend. We had size=2
min_size=1 before.

Hi,

just to rule out the obvious, which size does the pool have? You aren't
running it with size = 2, do you?

Hi,

I have one damaged PG in my cluster. All OSDs are BlueStore. How do I
fix this?
