Hi,
I'm new to the list, and I promise I've search everywhere, high and
low. and I cannot find anyone having this problem, and I cannot figure out
how to fix it! =(
I've been given room on a windows share to stage my linux backups
[approx 200gb] near-line before they go to tape. I've mounted the share
using smbfs version 3.0.7
I can barely read python, so I've been unable to dig deeper than
this.. rdiff-backup is waaaay to convenient for the task of backing up unix
over smbfs to ntfs, I really have a difficult time believing nobody else is
doing this, what braindead thing am I doing wrong/missing?
In short, NFS [which isn't an option in my environment] works
peachy, but with SMBFS; python2.3 processes hang onto the rdiff-backup.tmp.0
directory, and b0rk city!
The rdiff-backup process fails with the following error:

I ran rdiff-backup thru idle [the python stepper of love] and figured out
that the "device or resource busy" message was indeed coming from the
operating system level.
To make a long story short, it's trying to erase:
rdiff-backup.tmp.0/
except, -before- i exit the stepper, and -after- rdiff-backup has dumped the
traceback, lsof is reporting:
--- START OF LISTING

my GUESS is this is why it's b0rking on trying to erase that directory. What
I don't get is; why, when I do the same thing on an NFS mount, do the
python2.3 processes not hang onto the directory and when I use SMBFS it
fails this way?
thanks in advance.
