cifs destination exception: listxattr failed

[jbd]

Hi,

I'm using Attic 0.13 from Debian Jessie and I've got a problem with my CIFS repository. It was working a few days ago, and of course, I'm absolutely unable to provide you what changed (did a bunch of apt-get upgrade)

My backup script looks like that :

REPOSITORY=/mnt/cifs
ATTIC_PASSPHRASE="XXXX"

export ATTIC_PASSPHRASE

# excluded directories
attic create --stats                            \
    $REPOSITORY::`date +%Y-%m-%d`               \
    /data                                       \
    --exclude /data/home/*/.cache               \
    --exclude /data/volatile                    \
    --exclude '*.pyc'                           \
    --exclude '*.o'                             \

And I've got this traceback :

Traceback (most recent call last):
  File "/usr/bin/attic", line 3, in <module>
    main()
  File "/usr/lib/python3/dist-packages/attic/archiver.py", line 715, in main

    item.update(self.stat_attrs(st, path))
  File "/usr/lib/python3/dist-packages/attic/archive.py", line 351, in stat_attrs
    xattrs = xattr.get_all(path, follow_symlinks=False)
  File "/usr/lib/python3/dist-packages/attic/xattr.py", line 25, in get_all
    for name in listxattr(path, follow_symlinks=follow_symlinks))
  File "/usr/lib/python3/dist-packages/attic/xattr.py", line 68, in listxattr
    raise Exception('listxattr failed')

I've instrumented the code to show the error code, which "22" (Invalid argument). Any idea what could cause it ?

Do I understand correctly: CIFS is only the target fs where your repository is? But everything below /data is a Linux filesystem that should support extended attributes? Because it looks like it is stumbling over sth at the source, not at the target.

Since your report was a while ago: can you reproduce with attic 0.14?

OK. I thought it might be helpful to know that this issue can still be found in more current code. Posted on #1462

I believe I've run into the same issue as the OP from 2 years ago and I'm using a recent version of attic. I run attic through a systemd task and lately it has been failing. Here's the error output from systemd:

$USER@$HOST:~$ systemctl status attic

My OS is Arch Linux. Attic reports itself in the help as version 0.16. Does this look like a match for this issue and if so, what other info should I provide to help?
