得到每个osd的放置组个数
Get the Number of Placement Groups Per Osd

ceph pg dump | awk ' /^pg_stat/ { col=1; while($col!="up") {col++}; col++ } /^[0-9a-f]+\.[0-9a-f]+/ { match($0,/^[0-9a-f]+/); pool=substr($0, RSTART, RLENGTH); poollist[pool]=0; up=$col; i=0; RSTART=0; RLENGTH=0; delete osds; while(match(up,/[0-9]+/)>0) { osds[++i]=substr(up,RSTART,RLENGTH); up = substr(up, RSTART+RLENGTH) } for(i in osds) {array[osds[i],pool]++; osdlist[osds[i]];}}END { printf("\n"); printf("pool :\t"); for (i in poollist) printf("%s\t",i); printf("| SUM \n"); for (i in poollist) printf("--------"); printf("----------------\n"); for (i in osdlist) { printf("osd.%i\t", i); sum=0;   for (j in poollist) { printf("%i\t", array[i,j]); sum+=array[i,j]; sumpool[j]+=array[i,j] }; printf("| %i\n",sum) } for (i in poollist) printf("--------"); printf("----------------\n"); printf("SUM :\t"); for (i in poollist) printf("%s\t",sumpool[i]); printf("|\n");}'

结果
这里写图片描述

Copy-paste should work directly. The sum at bottom of the table must match to (pg_num x size).

You can find pg_num recommandations here : http://ceph.com/docs/master/rados/operations/placement-groups/

Also, a pg_num Calculator is avaible here : http://ceph.com/pgcalc
