Dear all

I have a SCO server with a mapping to a NFS share on a linux server. The Linux server went down and the mapping on the SCO server failed. Now when I run the df -k command on the SCO server, the NFS mapping is showing the following error:

df: cannot statfs maverick:/home/samba/sophos_install_files/scoopenserver/sav-in
stall : No such file or directory (error 2)

How do I kill the failed NFS mapping in order to create a fresh mapping?

Thanks

You should try to unmount the nfs mount and re-mount it if the linux server is back up.

When I run the umount command to unmount the corrupt nfs mapping, I get the following error message:

umount: could not unmount /usr/local/sav_install_files: No such file or director
y (error 2)

What is even more bizarre is that if I run the ls command in /usr/local (where the directory is located), it lists the sav_install_files directory, but if I run ls -l, it doesn't list it. If I try to delete the directory "sav_install_files", it says the directory doesn't exist.

I'm sure a reboot will fix the problem, but we have an important database running on it, so a reboot is not an option.

Of course it would - that is your mount point and should still be there.
Again, this would happen since your nfs is messed up.
You don't want to delete the directory.

Do a process status of the system - grep for nfs - I don't know what SCO runs, but there should be one or two processes - try killing those and restarting them (be aware if you have other nfs mounts they won't work so this may or may not be an option). Otherwise, I can't find any info for SCO on nfs stuff except this on SCOs Tech site

/usr/local/sav_install_files is a directory I've created manually, and I use it as mount point for the NFS mount to the linux box.

When I run ps -ef on the SCO box, it doesn't show any NFS processes running. I have a backup SCO box as well (with a working NFS mount to the linux box) and the backup box doesn't show any NFS processes either.

On a multi-threaded kernel, there may be no nfs processes. nfs can be built totally into the kernel. I'm not an SCO expert. Some versions of unix have a force unmount option. Others have a remount command. If you have neither, you are out of options.

Maybe you can make a directory /usr/local/temp and mount the directory there for now.
