I'm trying t umount an nfs mounted share but am told the resource is
busy. umount -f fails too.
So first I turned off all the xterms I had running which should have
killed any shell operating there.
Still says resouce is busy.
So trying to see what is doing it with `lsof'
However, when I run `lsof' (no arguments), it fails to produce any
output.
Just been setting there for 5-6 minutes, now. When I know from past
use it should have produced quite a pile of output.
I tried a lsof option that is supposed to show specifically nfs
related
( lsof -b /nfs/mount/point)
So trying it on the one reporting `busy'
lsof -b /projects
Which gave a gout of output with this kind of stuff in it:
lsof: avoiding readlink(/projects): -b was specified.
lsof: avoiding readlink(/): -b was specified.
lsof: avoiding stat(/): -b was specified.
lsof: WARNING: can't stat() rootfs file system /
Output information may be incomplete.
lsof: avoiding readlink(/): -b was specified.
lsof: avoiding stat(/): -b was specified.
lsof: WARNING: can't stat() reiserfs file system /
Output information may be incomplete.
[...]
Anyone know what might be going on here?
