1. PUT an object with some data :
curl -i -d "swiftonfile" http://localhost:8080/v1/AUTH_test/c1/file1 -X PUT

2. curl -i http://localhost:8080/v1/AUTH_test/c1/file1 -X GET

3. Observe the process by attaching to strace:
strace -ff -p 10245 -e open,close,dup

Process 19074 attached with 21 threads
[pid 19074] open("/mnt/gluster-object/test/c1/file1", O_RDONLY|O_CLOEXEC) = 10
[pid 19074] close(10)                   = 0
[pid 19074] close(6)                    = 0


4. # echo "aaaaaaaaaaa" > /mnt/gluster-object/test/c1/file1

[pid 19074] open("/mnt/gluster-object/test/c1/file1", O_RDONLY|O_CLOEXEC) = 10
[pid 19074] dup(10)                     = 12
[pid 19074] close(12)                   = 0
[pid 19074] close(10)                   = 0
