NFS filesystems not mounting at boot - can mount manually

["Thomas B. Walter" <tbw geo hunter cuny edu>]

Good Afternoon,

I have a lab of Dells running RHEL4u4. All but one NFS file systems are 
not mounting automatically at boot. If I manually issue command "mount -a" the 
offending file systems mount with no problems.

Contents of /etc/fstab:
everest:/scratch        /scratch nfs   soft,bg     0  0
yoda:/data/yoda/a         /data/yoda/a         nfs     soft,bg
yoda:/data/yoda/b         /data/yoda/b         nfs     soft,bg


Result of df -k command:
[root cslab2 log]# df -k
Filesystem           1K-blocks      Used Available Use% Mounted on

Both yoda and everest have entries in /etc/hosts.

I see System Error: No route to host(retrying) but I don't know why one 
NFS file system mounts and not the others.

TIA for any help.

Tom
