-#File Snapshot
-This feature gives the ability to take snapshot of files.
-
-##Descritpion
-This feature adds file snapshotting support to glusterfs. Snapshots can be created , deleted and reverted.
-
-To take a snapshot of a file, file should be in QCOW2 format as the code for the block layer snapshot has been taken from Qemu and put into gluster as a translator.
-
-With this feature, glusterfs will have better integration with Openstack Cinder, and in general ability to take snapshots of files (typically VM images).
-
-New extended attribute (xattr) will be added to identify files which are 'snapshot managed' vs raw files.
-
-##Volume Options
-Following volume option needs to be set on the volume for taking file snapshot.
-
-    # features.file-snapshot on
-##CLI parameters
-Following cli parameters needs to be passed with setfattr command to create, delete and revert file snapshot.
-
-    # trusted.glusterfs.block-format
-    # trusted.glusterfs.block-snapshot-create
-    # trusted.glusterfs.block-snapshot-goto
-##Fully loaded Example
-Download glusterfs3.5 rpms from download.gluster.org
-Install these rpms.
-
-start glusterd by using the command
-
-    # service glusterd start
-Now create a volume by using the command
-
-    # gluster volume create <vol_name> <brick_path>
-Run the command below to make sure that volume is created.
-
-    # gluster volume info
-Now turn on the snapshot feature on the volume by using the command
-
-    # gluster volume set <vol_name> features.file-snapshot on
-Verify that the option is set by using the command
-
-    # gluster volume info
-User should be able to see another option in the volume info
-
-    # features.file-snapshot: on
-Now mount the volume using fuse mount
-
-    # mount -t glusterfs <vol_name> <mount point>
-cd into the mount point
-    # cd <mount_point>
-    # touch <file_name>
-Size of the file can be set and format of the file can be changed to QCOW2 by running the command below. File size can be in KB/MB/GB
-
-    # setfattr -n trusted.glusterfs.block-format -v qcow2:<file_size> <file_name>
-Now create another file and send data to that file by running the command
-
-    # echo 'ABCDEFGHIJ' > <data_file1>
-copy the data to the one file to another by running the command
-
-    # dd if=data-file1 of=big-file conv=notrunc
-Now take the `snapshot of the file` by running the command
-
-    # setfattr -n trusted.glusterfs.block-snapshot-create -v <image1> <file_name>
-Add some more contents to the file and take another file snaphot by doing the following steps
-
-    # echo '1234567890' > <data_file2>
-    # dd if=<data_file2> of=<file_name> conv=notrunc
-    # setfattr -n trusted.glusterfs.block-snapshot-create -v <image2> <file_name>
-Now `revert` both the file snapshots and write data to some files so that data can be compared.
-
-    # setfattr -n trusted.glusterfs.block-snapshot-goto -v <image1> <file_name>
-    # dd if=<file_name> of=<out-file1> bs=11 count=1
-    # setfattr -n trusted.glusterfs.block-snapshot-goto -v <image2> <file_name>
-    # dd if=<file_name> of=<out-file2> bs=11 count=1
-Now read the contents of the files and compare as below:
-
-    # cat <data_file1>, <out_file1>  and compare contents.
-    # cat <data_file2>, <out_file2>  and compare contents.
-##one line description for the variables used
-file_name = File which will be creating in the mount point intially.
-
-data_file1 = File which contains data 'ABCDEFGHIJ'
-
-image1 = First file snapshot which has 'ABCDEFGHIJ' + some null values.
-
-data_file2 = File which contains data '1234567890'
-
-image2 = second file snapshot which has '1234567890' + some null values.
-
-out_file1 = After reverting image1 this contains 'ABCDEFGHIJ'
-
-out_file2 = After reverting image2 this contians '1234567890'
