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.
