Hi, I've got a 7.2-RELEASE box that has it's root file system mounted read/only via NFS. It hangs when trying to shutdown, at the "Writing entropy file:" point. Having chased this down - it hangs *any* time you try to rm' a file off of the filesystem. e.g. If I do: " recovery# cd / recovery# touch test touch: test: Read-only file system recovery# rm COPYRIGHT nfs server 10.0.0.1:/usr2/boot/os/7.2-i386: not responding nfs server 10.0.0.1:/usr2/boot/os/7.2-i386: not responding nfs server 10.0.0.1:/usr2/boot/os/7.2-i386: not responding " That last error is just repeated for infinity at about 5-10 second intervals. Any suggestions? The NFS server exports line being used is: " /usr2/boot/os -alldirs -maproot=root -ro -network 10.0.0.1 -mask 255.255.255.0 " The reason for the shutdown hang is that '/etc/rc.d/random' rm's the '/entropy' file if it exists as the system shuts down, and that rm never returns (the error output is redirected so you never see the errors) :( -Karl
