NFS mounts in fstab not mounting at boot

Here Guys,

as always, thanks for the assistance. I have some nfs entries in my fstab as follows :

nfsserver:/pfs/data/SAS/sas/vrdc/logs /sas/vrdc/logs nfs noatime,nodiratime,_netdev 0 0

When the server reboots, these mounts do not get mounted. However, a

mount -a , works fine.

I am using nfs version 4.

Thanks for your help with this.
