It still exists in autofs4 because, like Dennis said, it's really a mount/nfs issue, not autofs. If you run a mount -t nfs you'll note that the IP of the server is stored in the mount into. It's ugly, but one fix I've found to clear these up is to temporarily setup an aliased ethernet entry with the IP of the server and netmask 255.255.255.255 (so you don't lose contact with a whole network), umount the mount, then shut down that aliased ethernet entry, and let automounter remount the path on the hosts' new ip. This is on each client btw. i.e. if the host was 10.0.0.10 and is now 10.0.1.10, mount will show something like: myhost:/some/path on /some/path type nfs (rw,noquota,addr=10.0.0.10) do something like: ifconfig eth0:1 inet 10.0.0.10 netmask 255.255.255.255 up umount /some/path ifconfig eth0:1 down ls /some/path so that automount remounts it on new host ip... and you should be ok. I'm working on an audit script to do just this on our /net path, because /net is used by a lot of our engineers to access other desktop's local disk/scratch space, and when users' move... the machines move and often get re-IPd. I've noted that when a box moves, and then things like df hang, the automount daemon on /net will hang when checking for paths to expire and will never expire any anymore. It will however still respond to and mount new /net requests. So eventually a host can hit the max number of allowable mounts. -- Mike Marion-Unix SysAdmin/Staff Engineer-http://www.qualcomm.com [Joe just pulled Antonio away from a beautiful woman he was talking to, to move a cabinet a tiny bit] Antonio: "We barely moved it!"
