[StarCluster] List of EBS volumes on Master node

There is a discrepancy between the volumes listed from the Master node and
the volumes listed on the AWS EC2 Management Console. The EBS volumes
listed in the Management Console is correct.

Using the command fdisk -l from sshmaster on my cluster lists 4 450Gb
volumes that I did not create; as follows:

Disk /dev/xvdb1: 450.9 GB, 450934865920 bytes
255 heads, 63 sectors/track, 54823 cylinders, total 880732160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/xvdb1 doesn't contain a valid partition table

Disk /dev/xvdc1: 450.9 GB, 450934865920 bytes
255 heads, 63 sectors/track, 54823 cylinders, total 880732160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/xvdc1 doesn't contain a valid partition table

Disk /dev/xvdd1: 450.9 GB, 450934865920 bytes
255 heads, 63 sectors/track, 54823 cylinders, total 880732160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/xvdd1 doesn't contain a valid partition table

Disk /dev/xvde1: 450.9 GB, 450934865920 bytes
255 heads, 63 sectors/track, 54823 cylinders, total 880732160 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

Disk /dev/xvde1 doesn't contain a valid partition table

Any comments or suggestions greatly appreciated!
