[root@node235 ceph]# cat get.sh 
#! /bin/bash
IFS=$'\n\n' 
for osd in `ceph osd dump|grep osd|grep -v req|grep -v max|awk '{print $1,$19}'`
do 

osdnum=`echo  $osd|awk '{print $1}'`
osdid=`echo  $osd|awk '{print $2}'`
vgname=`lvdisplay |grep $osdid -A 1|tail  -n 1|awk '{print $3}'`
pvname=`pvdisplay |grep $vgname -B1|head -n 1|awk '{print $3}'`

echo $osdnum  $osdid  $vgname  $pvname

done

效果
