There are four directories:
. linux-3.5/: our modified linux kernel
. icefs/: icefs source code
. e2fs/: our modified e2fsprogs
. online_fsck/: our online fsck tool based on ioctl   


Install our linux kernel
. cd linux-3.5/
. make
. make modules
. make modules_install
. make install
. reboot 


Compile icefs and insert the icefs kernel module
. cd icefs/
. make
. insmod iext3.ko


Compile e2fsprogs for mkfs and fsck
. cd ie2fs/build/
. ../configure
. make


Compile online fsck tool
. cd online_fsck/
. gcc fsck_daemon.c -o fsck_daemon 


Create cubes in user space
. modify cube.c for different requirement 


To get a simple run:
. use e2fsprogs to create an icefs on a device
. mount icefs
. create cubes with cube.c 
. run your workload inside cubes
