Manually umounting the nfs drive (after the computer which hosts the nfs drive is switched off) just leads to a hang, whether the "lazy" switch is applied or not. In fact I cannot even type the umount command entirely: the system hangs immediately after typing the first 3 characters (including the leading /) of the mount point. Anyway it seems (from /etc/init.d/umountnfs.sh) that the -l switch, as well as the -f switch, is already applied by default. Running Sid; kernel is a stock Debian one: 2.6.25-2-686 #1 SMP Wed May 14 16:42:03 UTC 2008 i686 GNU/Linux It seems that nfs on the remote computer fails to send a command (before shutting itself down) to the computers to which it exports, telling them to umount. This may be a bug, or, much more likely, a failure on my part to understand the nfs export system. Anyway, I never had this trouble while samba was used for sharing, rather than nfs.
