Description

In my cluster, I configured k+m to be equal to 30+4, and there are 3 pgs in the cluster that cannot reach active+clean. If the value of k continues to increase, the number of pgs that cannot reach active+clean will continue to increase, for example, k+m When it is equal to 32+4, the number of pgs that cannot reach active+clean reaches 62, then the value of k can only be less than 30 at most?
