#!/bin/sh

# This script will find the locally active osd-s and display their information with the help of Megacli tools.
# Assumes that you run it on a host which has at least 1 osd that matches hdd or ssd disk device class in ceph osd df tree output.
#
# An example for usage:
# for NUM in 14 2 3 4 6 ; do printf "server$NUM\n" >> /tmp/osd_infos; ssh root@server"$NUM".place6.ungleich.ch "/opt/ungleich-tools/map-osd-to-disktype" >> /tmp/osd_infos ; printf "\n \n" >> /tmp/osd_infos; done
# 
# llnu's most hacky/advanced script at the time of writing (2020-05-27)


# Future functionality (arguments, and filtering):
#OSDTYPE=ssd
