Error on mounting OST. Can you please help on this.

[root@10-64-13-39 xxx-user]# mount -t lustre /dev/xvdx /mnt/ost0
mount.lustre: mount /dev/xvdk at /mnt/ost0 failed: No such file or directory
Is the MGS specification correct?
Is the filesystem name correct?
If upgrading, is the copied client log valid? (see upgrade docs)
