I would have done this long time ago. But I still feel unable to provide enough useful information. I also can not believe, that I'm the one, who has experienced this first. There must be some existing bug report somewhere. But I was unable to find it. Any hints anybody? Although: I'm pretty sure, this might be a problem caused within the kernel itself. This is because even a umount -f hangs uninteruptable for at least long enough for me to become impatient (I didn't say "forever"). May be it is a design problem of the stateless NFS protocol in general? > Information from: > http://nfs.sourceforge.net/nfs-howto/ar01s04.html#mounting_remote_dirs > > Mounting options: > hard > > The program accessing a file on a NFS mounted file system will hang > when the server crashes.

We recommend using hard,intr on all NFS mounted file systems. I've already tried options "hard,intr" and even "soft,intr" on a wide range of Linux systems. But if a mounted NFS server has become unreachable, even trying to reboot the NFS Linux clients takes "forever", so if you need to get these client system back online in acceptable time, pressing the hard reset switch was often the only choice I had. This was with SuSE Linux, Red Hat, Debian and Ubuntu systems in several different versions. > If you do fill a new bug report, please let me know. > Thanks in advance, ditto. I would also appreciate any pointer to locations to learn more about this...
