and mount-a gives you the following error.
mount.nfs: access denied by server while mounting /blah_blah_blah/blah_blah
Chances are, your machine has been upgraded and now uses the NFS version 4 as default nfs version
instead of 3
To fix this issue you need to explicitly tell nfs to mount your share using the older nfs version 3
simply add nfsvers=3 to your nfs mount stanza in your /etc/fstab file
192.168.1.10:/shared/files /mnt/files nfs soft,intr,nfsvers=3 0 0
save the file and type
Your nfs mounts will now work.
