Hi Josh,

the backport has already happened in PR 1667. You can try the pre-release packages from these subscription repositories:
https://download.bareos.com/bareos/testing/CD/bareos-22

Version 22.1.4~pre39 (and every newer version) should contain the fix. You can safely install the packages from there. An upgrade to the upcoming version 22.1.4 will be seamless.

Best Regards,
Andreas

I've only tested with one client, but 24.0.0~pre187.8e12c147a did work with no VSS errors. I'll be watching for this to be backported to 22 (subscription).

    We managed to reproduce the issue.  As you already noted, the
    cause was the "connection from client to director" option.

    This was fixed by https://github.com/bareos/bareos/pull/1665
    <https://github.com/bareos/bareos/pull/1665>

    The current next release ( https://download.bareos.org/next/
<https://download.bareos.org/next/> ) already contains the fix. Let me know if you tried that version and the issue still persists!

    Sincerly

    Interesting. We have a mix of client-initiated and not, and at a
    glance it looks like the only jobs that ever have warnings
    ("ERR=The process cannot access the file because it is being used
    by another process.") are the ones from clients with "Connection
    From Client To Director = yes". Seems like maybe there's a
    different code path used when that's enabled, and it hits a bug.
    Unfortunately we can't switch away from client-initiated for
    these, we've just been living with the warnings.

        I switched the client connectivity to the "normal" mode
        (director to client) and the job completed OK and I had no
        problems accessing the registry file.

            Hi Sebastian.

            Thx for looking into it. This is the job log. Not much
            interesting stuff in there.

            The same thing (the jobid being zero in the trace log)
            was in the previous trace I attached excerpt from few
            days ago. But that one was from a different machine.
            That was a clean win10 installation just for testing the
            FD, this one is my production setup. Anyway, one thing
            that can be relatively uncommon (but I don't see why it
            should affect anything about the job itself) is that I
            use passive clients (Connection From Client to
            Director=yes, Heartbeat Interval=60).

            Hi Spadajspadaj,

            something is wrong with your debug output but im not
            sure why.  Debug messages are normally formatted as

            daemon-name (level): file:line-jobid
            For some reason your jobid is 0 (which often means it
            could not be determined) here.
            This should normally not happen and might be why the
            vss name translation does not work for you.

            I tried reproducing the problem you described with your
            fileset, but it just works for me.
            Would it be possible for you to also submit the joblog
            for that particular job ?
            You can retrieve it using "list joblog jobid=17062".

            Sincerely
            Sebastian Sura
