Hi Greg,

Do you have any idea about the health warning?

Hi 

We have created EC pool ( k =10 and m =3) with 540 osds. We followed the following rule to calculate the pgs count for the EC pool.  

                   (OSDs * 100)
Total PGs =  ------------
                        pool size

Where pool size is either the number of replicas for replicated pools or the K+M sum for erasure coded pools 

Total pgs = 540 *100/13 = 4153.8 Nearest power of 2: 8192

So we have configured 8192 as the EC pool pg size. But we are getting health HEALTH_WARN ; too few pgs per osd (15 < min 20). we checked all the osds and it has more than 80 pgs 

What's wrong here?
