> Initial SCM roles as following:
> bash-4.2$ ozone admin scm roles
> [scm1:9865:FOLLOWER, scm2:9865:FOLLOWER, scm3:9865:LEADER]
> Running freon random key generator as following:
> ozone freon randomkeys --numOfVolumes=10 --numOfBuckets 50 --numOfKeys 50
> --replicationType=RATIS --factor=THREE
> While freon randomkeys was running, put all SCM nodes under blockade and stop
> leader SCM node:
> blockade status:
> NODE CONTAINER ID STATUS IP NETWORK PARTITION
