How to tell which systems are mounting NFS exports

Andrew Kaplan — Mon, 07 Dec 2009 15:48:27 GMT

Hi there --

I want to unmount an NFS export but I am unable to do so because the mount is busy. What command(s) can I use to determine what client systems are currently mounting the export in question? Thanks.

You can use "showmount -e" command to check...

also you can use "fuse -cu " command to check if it is used by any local process...

hi

the command would be

showmount -a

this would show the clients that have mounted the servers exported fileystems.

Hi there --

Thank-you for your reply. The showmount command does help. What I am looking for is what systems currently have the export in question mounted. Also, if necessary, is there a way to force the mount in question to be unmounted? Thanks.

suppose your server has exported /home/test

you can use
fuser -cu /home/test -- to know what processes are accessing that file system.

then after that

fuser -kcu /home/test

to kill all the processes that are using thast filesystem.
Cuation: that fuser -kcu would terminate all the proceses as well as the user processes that are accessing that fileysten at that time.

# showmount -a SERVER

man 1m showmount:
"-a Print all remote mounts in the format"

Hi,
Just an addition I miss all the time is to unshare a NFS share before umounting it.

Hi,

look at the content of /etc/rmtab and see who all currently have nfs export mounted on them.

Unmount the export from all clients , this is to ensure none of the client goes to nfs stale condition if you unmount nfs export.

Once done do

stop nfs server on nfs master

unmount -- if still doesn't work do fuser -ku on mount point -- umount
