fedora core 6 cannot nfs mount sub directory


I am having problem NFS mounting a subdirectory of an exported directory.

We have an Auspex NFS server which exports directories as follows:

/exp/apex
/exp/Administrator
/exp/public


I mount the directories as follows on AIX, Solaris, HP-UX, Gentoo Linux, Red Hat 7.3,
Fedore Core 2, Red Hat 8.0., Fedora Core 6 32-bit (2.6.18-1.2798.fc6).

mount auspex:/exp/apex /apex
mount auspex:/exp/public /usr/spool/public
mount auspex:/exp/Administrator/gblcode/cob /home/gblcode/cob
mount auspex:/exp/Administrator/gblcode/dbcob /home/gblcode/dbcob
mount auspex:/exp/Administrator/modsman /home/modsman/modsman


On fedora core 6 (2.6.22.7-57.fc6), When system boots it mounts /apex and /usr/spool/public, but it only mounts the first directory from /exp/Administrator.

I re-arranged the order and it will always mount /apex and /usr/spool/public, but it mounts only the first directory from /exp/Administrator.

When I try to manually mount the directory, I get error that the directory is busy or already mounted.

When it force mount it (mount -f) it mounts the directory, but when I try to access it (ls command) sometimes it displays directory listing and sometimes it does not.

Anyone know what the problem could be? How do I fix it?

I think this system is a 64-bit other systems are 32-bit. How do I find out if the kernel is a 32-bit or 64-bit kernel?

Thanks.

I fixed the problem. 2.6.22 kernel apparently broke NFS.
Install latest nfs-utils and add nosharecache to mount option.

For more info take a look at following URLs:
