$ echo store.vdiskhub.com 9111 [email protected] mypassword > /sys/fs/vdisk/mysession/connect

#generate AES-256 key in hex form
$ echo mydiskpassword | sha256sum | awk '{ print $1 }'

#open existing 'mydisk' disk
$ echo mydisk mykey > /sys/fs/vdisk/mysession/open_disk

#or create new 'mydisk' with size 256MB
$ echo mydisk 256 mykey > /sys/fs/vdisk/mysession/create_disk

#get block device number
$ cat /sys/fs/vdisk/mysession/mydisk/number

#format disk as EXT4 file system
$ mkfs.ext4 /dev/vdisk{number}

#mount disk
$ mkdir /mnt/mydisk && mount /dev/vdisk{number} /mnt/mydisk

#work with data
$ cd /mnt/mydisk && ...

#unmount disk
$ umount /dev/vdisk{number} #unmount disk

#close disk and delete session
$ echo mysession > /sys/fs/vdisk/delete_session

#unload kernel module
$ rmmod vdisk
