3. python /small-files/smallfile/smallfile_cli.py --operation create --threads 8 --file-size 64 --files 1000 --top /gluster-mount --pause 10000 --host-set "`echo $CLIENT | tr ' ' ','`"


python /small-files/smallfile/smallfile_cli.py --operation read --threads 8 --file-size 64 --files 1000 --top /gluster-mount --pause 10000 --host-set "`echo $CLIENT | tr ' ' ','`"


python /small-files/smallfile/smallfile_cli.py --operation append --threads 8 --file-size 64 --files 1000 --top /gluster-mount --pause 10000 --host-set "`echo $CLIENT | tr ' ' ','`"


python /small-files/smallfile/smallfile_cli.py --operation rename --threads 8 --file-size 64 --files 1000 --top /gluster-mount --pause 10000 --host-set "`echo $CLIENT | tr ' ' ','`"


python /small-files/smallfile/smallfile_cli.py --operation delete-renamed --threads 8 --file-size 64 --files 1000 --top /gluster-mount --pause 10000 --host-set "`echo $CLIENT | tr ' ' ','`"
