Stale NFS file handle

[Posey, Jake E]

Is there a way to clear stale nfs mounts without rebooting the nfs
client?

 

I have a file system that is mounted on 2 systems.  On system a the file
system is fine, but on system b the file system is stale.  It looks like
the mount point lost it's inodes

 

?---------  ? ?    ?       ?            ? sw

 

I tried umounting the file system but now luck.

 

[root at lcas100 export_intel_boeing]# umount
/export_intel_boeing/sw/fsl/gscm/intel

umount: /export_intel_boeing/sw/fsl/gscm/intel: Stale NFS file handle

umount: /export_intel_boeing/sw/fsl/gscm/intel: Stale NFS file handle

[root at lcas100 export_intel_boeing]#

 

I even tried using the -f option to force a umount but got the same
results.  I also tried re-exporting the file system on the nfs server,
same results.

 

Is there another way to unmount the file system without rebooting the
nfs client?

 

Note: the file system is in a SAN environment on a EMC NS600.

 

Thanks for your assistance.
