lsof is very useful to the system administrator trying to umount an otherwise busy filesystem.
But if you are still getting device busy error messages from umount, even if lsof doesn't find any remaining processes on this device, think about the nfsserver: On Linux there is the kernel based NFS server and lsof is unable to see, that this process is still blocking the device in question. Solution is simple:<nobr> <wbr></nobr>/etc/init.d/nfsserver stop and voila<nobr> <wbr></nobr>... umount does now work.

lsof is nice, but can't see devs open by knfsd
