I have a optimize script that I run after the reboot of a ceph node. It
sets among other things /sys/block/sdg/queue/read_ahead_kb and
/sys/block/sdg/queue/nr_requests of block devices being used for osd's.
Normally I am using the mount command to discover these but with the
tmpfs and ceph-volume this does not work.
Is anyone able to share a simple onliner getting from osd's the used
block devices? Eg from both types at the same time. Or do I really need
to traverse this block -> /dev/mapper/... ?
