Comment 21 for bug 792763

Ubuntu 12.10, Linux tweedle 3.5.0-23-generic #35-Ubuntu SMP Thu Jan 24 13:05:29 UTC 2013 i686 i686 i686 GNU/Linux

 smbd --version Version 3.6.6

After reading down these posts, I think your real problem is with SMB. After a Ubuntu upgrade last spring I've had random, persistent and transient SMB errors that get logged but that do not seem to have any serious effect. NOTE that I haven't been paying a lot of attention to this because the SMB problem seems to immediately resolve itself (the SMB process re-spawns?) and life goes on.

This *may* be the most recent of those, can't recall the exact date and time:

OK.

I too have suddenly begun seeing the Duplicity errors yesterday and today.

I too have a Duplicity archive file as a zero-length file on my backup device (Netgear NAS which works perfectly in all other regards).

I too cannot directly delete that zero-length file "Device or resource busy".

I too cannot *usually* unmount the Netgear NAS backup share in Nautilus -- but today I can, and when I do a 'ps ax grep 'dup'' I do NOT see the following Python script running now that the backup has failed:

32178 ? DNsl 7:43 /usr/bin/python /usr/bin/duplicity --include=/home/jsage/.cache/deja-dup/metadata --include=/home/html/www.finchhaven.com --exclude=/home/jsage/Downloads --exclude=/home/jsage/.local/share/Trash --exclude=/home/jsage/.xsession-errors --exclude=/home/jsage/.thumbnails --exclude=/home/jsage/.gvfs --exclude=/home/jsage/.adobe/Flash_Player/AssetCache --exclude=/home/jsage/.cache/deja-dup --exclude=/home/jsage/.cache --include=/home/jsage --exclude=/sys --exclude=/proc --exclude=/tmp --exclude=** --gio --volsize=25 / smb://finchnet-nas.local/backup/Tweedle --no-encryption --verbosity=9 --gpg-options=--no-use-agent --archive-dir=/home/jsage/.cache/deja-dup --log-fd=19

In the past I have not been able to unmount the Netgear backup share because some (unknown at that time) Python script had it "busy".
