Hi All,
I just created this little bash script to retrieve the "/dev/disk/by-id"
string for each OSD on a host. Our disks are internally mounted so have no
concept of drive bays, this should make it easier to work out what disk has
failed.
#!/bin/bash
DISKS=`ceph-disk list | grep "ceph data"`
old_IFS=$IFS
IFS=$'\n'
echo $DISKS
for DISK in $DISKS; do
DEV=`awk '{print $1}' <<< $DISK`
OSD=`awk '{print $7}' <<< $DISK`
DEV=`echo $DEV | sed -e 's/\/dev\///g'`
ID=`ls -l /dev/disk/by-id | grep $DEV | awk '{print $9}' | egrep -v
"wwn"`
echo $OSD $ID
done
IFS=$old_IFS
