umount: 1831-015 16 error while unmounting server:/dir

[bandez]

Hi ,

I got the following error message during I tried to umount an fs via nfs.
The source ip address was changed, I think that was the reason I got this message.
I cannot execute ls -la in the / because it hangs.
Also the umount, umount -f and df .
What can I do ? Reboot is not possible, neither ipcrm!
Thanks in advance!!

Have you tried changing the ip-address to what it was before the problem?
Perhaps changing your hostfile to let the old hostname point to the new ip-address helps, or by changing /etc/filesystems by hand (carefull).

Hi rick26 ,

Thanx your answer.

No, I not tried to change the ip address to the old because it not possible (customer request needed).
It is not in the /etc/filesystem.
It has no effect if I change the hosts file.

Any idea??
