Configuring Ceph with Blkin

ssh into VM1 where Ceph is Deployed

ssh centos@128.31.25.229 -A

cd ceph/build

Startup Ceph with desired configurations

OSD=3 MON=3 RGW=1 ../src/vstart.sh -n

Stop Ceph so that the tracepoints can be enabled.:

/home/centos/ceph/src/stop.sh

Start up an Lttng session and enable tracepoints

lttng create blkin-test

lttng enable-event --userspace zipkin:timestamp

lttng enable-event --userspace zipkin:keyval

lttng start

Startup Ceph again

OSD=3 MON=3 RGW=1 ../src/vstart.sh -n

Go to a parallel terminal to run this

ssh centos@128.31.25.229 -A

~/ceph/build/bin/ceph-mgr -i x -c ~/ceph/build/ceph.conf

Now put something in using rados, check that it made it, get it back, and remove it

./bin/rados mkpool test-blkin

./bin/rados put test-object-1 ../src/vstart.sh --pool=test-blkin

./bin/ceph osd map test-blkin test-object-1

./bin/rados get test-object-1 ./vstart-copy.sh --pool=test-blkin

md5sum vstart*

./bin/rados rm test-object-1 --pool=test-blkin

Now stop Lttng session and see what was collected

lttng stop

lttng view
