Open Stack

hello all!


I am installing and configuring swift using the commands given in the 
book "software defined storage with openstack swift" by Joe Arnold.

I am working on Ubuntu 12.04
I had downloaded swift, install it, configure files, prepare the drives, mount and reboot
Then, I again give 'mount' command and following results are recieved.

arun at arun-Aspire-5742:~$ mount
/dev/sda4 on / type ext4 (rw,errors=remount-ro)
proc on /proc type proc (rw,noexec,nosuid,nodev)
sysfs on /sys type sysfs (rw,noexec,nosuid,nodev)
none on /sys/fs/fuse/connections type fusectl (rw)
none on /sys/kernel/debug type debugfs (rw)
none on /sys/kernel/security type securityfs (rw)
udev on /dev type devtmpfs (rw,mode=0755)
devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620)
tmpfs on /run type
 tmpfs (rw,noexec,nosuid,size=10%,mode=0755)
none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880)
none on /run/shm type tmpfs (rw,nosuid,nodev)
gvfs-fuse-daemon on /home/arun/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=arun)


Then, I proceed further for creating the builder files

I was doubtful that these results are not correct and there is some problem in creating builder files.

I install the python package dnspython using  'apt-get install' command
Then, I try to create builder file
But, again, I get the  same error

please help me in this regard
