Update with docker-compose rsync: delete_file problem

FabCocco · June 21, 2019, 1:29pm

Hi

i’m running nextcloud with docker compose, but when i stop, pull and restart it to update the packages i fall in a endless loop of:

 Initializing nextcloud 16.0.1.1 ...
nextcloud       | rsync: delete_file: rmdir(logs) failed: Device or resource busy (16)
nextcloud       | rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1196) [sender=3.1.2]

I don’t know where to start searching a mistake.

Thank you very much!

I am leaving some notes here, in case someone else experiences a similar situation and is being sent here by a search engine. To find out what was going on in a similar case, I ran

docker-compose run --rm app /bin/bash

and typed the rsync command from

github.com

nextcloud/docker/blob/73ff5c860d155d46ed65b6ae9caa9ee6e64478de/15.0/fpm/entrypoint.sh#L61


echo "Initializing nextcloud $image_version ..."
if [ "$installed_version" != "0.0.0.0" ]; then
    echo "Upgrading nextcloud from $installed_version ..."
    run_as 'php /var/www/html/occ app:list' | sed -n "/Enabled:/,/Disabled:/p" > /tmp/list_before
fi
if [ "$(id -u)" = 0 ]; then
    rsync_options="-rlDog --chown www-data:root"
else
    rsync_options="-rlD"
fi
rsync $rsync_options --delete --exclude-from=/upgrade.exclude /usr/src/nextcloud/ /var/www/html/


for dir in config data custom_apps themes; do
    if [ ! -d "/var/www/html/$dir" ] || directory_empty "/var/www/html/$dir"; then
        rsync $rsync_options --include "/$dir/" --exclude '/*' /usr/src/nextcloud/ /var/www/html/
    fi
done
rsync $rsync_options --include '/version.php' --exclude '/*' /usr/src/nextcloud/ /var/www/html/
echo "Initializing finished"


#install

or similar manually, by invoking

rsync -rlD --delete --exclude-from=/upgrade.exclude /usr/src/nextcloud/ /var/www/html/

on the shell and at least reproducing the same error.

Trying to find out which resource was using it

installing lsof with apt update && apt install -y lsof didn’t yield the expected result. The file was also not accessed anywhere in the host system. What happened?

It turned out there was still a host volume mounted in that directory, so it could not be removed. Taking it out in the docker-compose.yml file helped resolving the update blocker.

May it be that you mounted the logs directory via a Docker volume, too?
