--- Begin Message ---Package: mount Version: 2.20.1-5.3 Severity: normal Dear Maintainer, * What led up to the situation? Mount nfs - suspend/disable networking -> NFS Mount is broken, Server unreachable. Kernel renames mountpoint to "/mnt/point (deleted)" (see fs/dcache.c in linux kernel) which is a bug in itself. * What exactly did you do (or not do) that was effective (or ineffective)? Nothing - i found no way of unmounting the now broken NFS. This is the result in /proc/mounts: flo@p2:~$ cat /proc/mounts | grep nfs4 pobox:/scratch/local /scratch/pobox\040(deleted) nfs4 rw,nosuid,nodev,noexec,relatime,vers=4,rsize=262144,wsize=262144,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.177.145,minorversion=0,local_lock=none,addr=192.168.177.1 0 0 Trying to unmount /scratch/pobox returns: is not mounted (according to mtab) because /etc/mtab is a link to /proc/mounts which now contains garbage. Trying to unmount "/scratch/pobox\040(deleted)" returns the same. There is no way to unmount the nfs share.

It's not like we can change this behaviour now. I agree, but util-linux can't do anything at all and cannot change what the kernel does. Chris
