  • Warning: rsync is broken

    From alain williams@3:633/10 to All on Friday, June 19, 2026 12:40:01
    I am running Debian 13.

    rsync was broken a few weeks ago (in May).

    The symptom is error messages 'Invalid argument (22)' when trying to read files. (The 22 is the errno value).

    See: https://github.com/RsyncProject/rsync/issues/897

    Note the workaround commented by ovalhub:

    I was able to find a workaround for this bug with a rsyncd.conf change.
    As explained above and in #922, the issue is triggered when a module has path = /.
    With use chroot = yes, you can set path = //.// for the same / result.
    I was then able to rsync / as desired.

    I use rsync for backups, this normally runs silently overnight. I did not see the huge number of error messages as rsync also hung and the script did not end and thus send me email.

    I think that this has now been fixed but has not appeared in Debian, yet. I implemented the workaround y/day.

    Regards

    You can solve this class of problems with the coreutils program
    "timeout". It will run a given program and kill it if it is
    still running after a configurable period of time.
