This is the big clue: you have two undersized PGs!

2147483647 is the largest number you can represent in a signed 32-bit
integer. There's an output error of some kind which is fixed
elsewhere; this should be "-1".
So for whatever reason (in general it's hard on CRUSH trying to select
N entries out of N choices), CRUSH hasn't been able to map an OSD to
this slot for you. You'll want to figure out why that is and fix it.
