Linux – refused mount request from 192.168.56.100 for /ovm/thepool1/poolfs (/): not exported

Am trying to setup NFS mount point between servers:-
db-rac and vm-manager. /ovm/mypool1/poolfs is a virtual disk mounted as shown below.

/dev/sdc 12G 159M 12G 2% /ovm/mypool1/poolfs

Following are my configurations:-

vm-manager(192.168.56.100):-

1) cat /etc/exports

/ovm/mypool1/poofs *(rw,no_root_squash)

2) [root@mymanager ~]# chkconfig nfs on

[root@mymanager ~]# service nfs start

[root@mymanager ~]# exportfs –a

3) [root@vm-manager ~]# df -h

db-rac(192.168.56.101):-

While running the command
[root@db-rac ~]#mount 192.168.56.100:/ovm/mypool1/poolfs /mnt -v

Am getting the error

mount: no type was given – I'll assume nfs because of the colon
mount: trying 192.168.56.100 prog 100003 vers 3 prot tcp port 2049
mount: trying 192.168.56.100 prog 100005 vers 3 prot udp port 867
mount: 192.168.56.100:/ovm/mypool1/poolfs failed, reason given by server: Permission denied

And checking the /var/log/messages

vm-manager mountd[2811]: refused mount request from 192.168.56.100 for /ovm/mypool1/poolfs (/): not exported

Appreciate for any help provided.
