CentOS FCSK Not Workng

I have moved my cloud instance into recvoery mode so i can run the check disk.  When i issue the FCSK i am given the following error:

sh-3.2# fsck /dev/sda2
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: No such file or directory while trying to open /dev/sda2

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device>

sh-3.2# fsck /dev/sda1
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
fsck.ext2: No such file or directory while trying to open /dev/sda1

The superblock could not be read or does not describe a correct ext2
filesystem.  If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
    e2fsck -b 8193 <device

Hi,

This is not about the system being a cloud server or not. Fscke is failing becasue your partitions are mounted .. You ahve 2 swap partitions which do not require checking so all you have is /dev/xvda1 and /dev/xvdb1..

Please post the output from your mount command so that I can give you the exact commands for remounting..

Cheers,
K.
