swift data servers are installed with less than 1GB device on data servers

[Dafna Ron]

I installed my setup with these swift configuration:

CONFIG_SWIFT_PROXY_HOSTS=10.35.***.**

# The password to use for the Swift to authenticate with Keystone
CONFIG_SWIFT_KS_PW=*****************

# A comma separated list of IP addresses on which to install the
# Swift Storage services, each entry should take the format
# <ipaddress>[/dev], for example 127.0.0.1/vdb will install /dev/vdb
# on 127.0.0.1 as a swift storage device(packstack does not create the
# filesystem, you must do this first), if /dev is omitted Packstack
# will create a loopback device for a test setup
CONFIG_SWIFT_STORAGE_HOSTS=10.35.***.***,10.35.***.***,10.35.***.***,10.35.***.***,10.35.***.***

# Number of swift storage zones, this number MUST be no bigger than
# the number of storage devices configured
CONFIG_SWIFT_STORAGE_ZONES=2

# Number of swift storage replicas, this number MUST be no bigger
# than the number of storage zones configured
CONFIG_SWIFT_STORAGE_REPLICAS=2

# FileSystem type for storage nodes
CONFIG_SWIFT_STORAGE_FSTYPE=ext4

it seems that the data servers are installed with a 1 GB size device:

[root@vm-161-189 swift]# df -h
Filesystem Size Used Avail Use% Mounted on

/srv/loopback-device/device1 960M 34M 876M 4% /srv/node/device1

If we install with a specific size we need to ask the user what it should be.

currently, installing from packstack leaves a system which is unusable
