NFS do not load at boot

[firak]

HI I use SLES 10 SP 2 and 32 SLED 11 in a LAN.

We use LDAP login and NFS filesystem.

Problem: NFS do not load at boot.

We have on SLES studentserver (10.44.154.41):

studentserver:~ # cat /etc/exports
/home   *(fsid=0,rw,sync,root_squash)

and

studentserver:~ # chkconfig -l | grep nfs
nfs                       0:off  1:off  2:off  3:on   4:off  5:on   6:off
nfsboot                   0:off  1:off  2:off  3:on   4:off  5:on   6:off
nfsserver                 0:off  1:off  2:off  3:on   4:off  5:on   6:off
studentserver:~ #

When the clients boots they do not find the studentserver (10.44.154.41). I check the filesystem on m08:

m08:~/Desktop # df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda6             31454268   4065900  27388368  13% /
udev                    506464       192    506272   1% /dev
/dev/sda1              1035692     14684    968396   2% /boot
/dev/sda7             43542792     32840  43509952   1% /local
m08:~/Desktop #

This is the filesystem on the client local HD.


Then I mount fstab:

m08:~/Desktop # mount -a
mount.nfs: mount system call failed
m08:~/Desktop # mount -a
mount.nfs: mount system call failed
m08:~/Desktop #

I ping the server:

m08:~/Desktop #  ping -c2 10.44.154.41

m12:~/Desktop #

Then I check the last 2 lines in fstab:

m08:~/Desktop #  tail -n2 /etc/fstab
devpts  /dev/pts        devpts  mode=0620,gid=5 0 0 
10.44.154.41:/home      /home   nfs     wsize=16384,rsize=16384,hard,intr 0 0 
m24:~/Desktop #

Then I mount fstab again:

m08:~/Desktop # mount -a
m08:~/Desktop #

Checking filesystem:

m08:~/Desktop #  df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda6             31454268   4065916  27388352  13% /
udev                    506464       192    506272   1% /dev
/dev/sda1              1035692     14684    968396   2% /boot
/dev/sda7             43542792     32840  43509952   1% /local
10.44.154.41:/home   488360960  26878608 461482352   6% /home
m08:~/Desktop #

From now on everything is fine until the clients shuts off, with the crontab command.


In Cool solutions I found:
"Suse NFS Client unable to get locks, especially after umount / remount"

m01:~/Desktop # chkconfig -l | grep nfs
nfs                       0:off  1:off  2:off  3:on   4:off  5:on   6:off
nfsserver                 0:off  1:off  2:off  3:off  4:off  5:off  6:off
m01:~/Desktop #

This is happening to 28 - 30 clients every day. It no system in which client logs in NFS at boot.

I definitely need some help here.
