Hi
I try to run a bench test on a RBD image and I get from time to time the
following in ceph status
cluster 046b0180-dc3f-4846-924f-41d9729d48c8
health HEALTH_WARN
2 requests are blocked > 32 sec

election epoch 18, quorum 0,1,2 aspen,ash,alder

client io 6083 B/s rd, 18884 kB/s wr, 75 op/s
what does "requests are blocked" mean ? and performance drops to almost 0 ?
I am running infernalis version on Centos 7 kernel 3.10.0-327.3.1.el7.x86_64
Thanks
