Hi,
After a cephadm upgrade from 18.2.2 to 18.2.7 that worked perfectly, I am noticing lots ( 42 out of 161 OSDs ) "slow operations in bluestore" errors
My cluster has all 3 types of OSDs ( NVME, SSD, HDD+ journaling)
I found some articles mentioning below setting but it did not help
Anyone else having this issue ?
Thanks Steven
