Linode every partition is corrupted but it works.

Hi all…

If I run "fdisk -l" command it shows this output:

Disk /dev/xvda: 12.7 GB, 12675186688 bytes
255 heads, 63 sectors/track, 1541 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

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

Disk /dev/xvdb: 268 MB, 268435456 bytes
255 heads, 63 sectors/track, 32 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

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

Disk /dev/xvdc: 8535 MB, 8535408640 bytes
255 heads, 63 sectors/track, 1037 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000

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

this command says that every partition present on my linode is corrupted.

How this is possible? The vps seems to work without any problem so what is corrupted? How can I solve this problem?

/dev/xvda is used for OS

/dev/xvdb is used for swap

/dev/xvdc is used for www dir

Thanks.
