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?
