Ceph » CephFS

This is hard to reproduce and for now need to perform some steps manually and run a qa test case using vstart_runnner

Steps to reproduce:

1) ./bin/cephfs-mirror --id mirror --cluster ceph -f --debug_cephfs-mirror=20
2) ./bin/ceph fs volume create a ; ./bin/ceph fs volume create b ; ./bin/ceph fs volume create c ; ./bin/ceph fs volume create d ; ./bin/ceph fs volume create e
3) ./bin/ceph mgr module enable mirroring 
4) ./bin/ceph fs snapshot mirror enable a ; ./bin/ceph fs snapshot mirror enable b; ./bin/ceph fs snapshot mirror enable c; ./bin/ceph fs snapshot mirror enable d; ./bin/ceph fs snapshot mirror enable e 
5) ./bin/ceph fs snapshot mirror peer_add a client.mirror_remote@ceph b; ./bin/ceph fs snapshot mirror peer_add c client.mirror_remote@ceph d
3) source ../../venv/bin/activate ; python ../qa/tasks/vstart_runner.py tasks.cephfs.test_mirroring.TestMirroring

wait for a few minutes and those line lines are in the logs after nothing is being executed:
