I'm trying to umount a NFS file system, and it returns "not mounted", but it shows in bfd and when I try to mount it again I get the error message "... is already mounted on...".
I already tried stopping and starting nfs.client, but got the same results. Any ideas?
Solved! Go to Solution.

Re: Unable to umount NFS file system
a)automounter , some of your processes is trying to access this directory constantly?
b)run from NFS server 'showmount' check that
client is not listed there.If it does - it's mounted (or pretends to look mounted :)
c)if not, try removing /etc/mnttab , run mount -v and bdf.
And by the way is everything ok with NFS server? (run 'rpcinfo

Re: Unable to umount NFS file system
Well, fuser shows no one, I'll try installing lsof.
The NFS server shows this file system mounted on this client. There are other file systems from the same NFS server mounted on this client, and they are all ok.
rpcinfo
Any more ideas?

SolutionOne trick that works, but you must be FAST!, is to rm /etc/mnttab or delete the entry for the mountpoint from /etc/mnttab
This will allow you a 10 second window or so to umount it... but comment out of /etc/fstab first...

Re: Unable to umount NFS file system
I was fast and then able to mount the file system. Problem is that now it is mounted twice (if I issue another umount it works, but only for the last mounted, the original still can not be umounted).
So, the problem is not solved, but I can at least use the file system until the server can be rebooted.
Rgds, Patricia.
