Wow. Great find. I have been mucking with debian lenny init scripts, configuration files, and anything else I could think of trying to get this to work properly for well over a month now. The only difference is I am using an active/passive setup. I've simulated about 1000 manual tests, and all worked fine. Not to beat a dead cat but.... Does the removal of the IP free up (or break) the file system locks that cause the file system unmount to hang? Have we encountered a bug in the Debian implementation of NFS? (because exportfs -u doesn't work as advertised) Thanks again.
