[ZendTo] my server became full

Tue Apr 2 16:18:15 BST 2024

I don’t appear to have such a log file, or any cron log file.

The cron log (/var/log/cron.log), would at least acknowledge that it ran and when.

e.g. Apr  2 12:05:01 (server) CROND[92540]: (root) CMD (find -H /var/zendto/incoming -type f -mmin +1440 -delete >/dev/null 2>&1)

Cheers

This was my first thought, but I don't *think* it logs anywhere... Looking at the entries in the cron they output to /dev/null and not to a log file.

> I haven't looked at the preferences file in ages; maybe there's an option in there that needs to be set to enable the cleanup?

Not that I can see

First, I'd check the log files to see if cron actually ran the job; if not maybe there's some info about why not.

I haven't looked at the preferences file in ages; maybe there's an option in there that needs to be set to enable the cleanup?

Hello all,

Two posts in two [working] days, sorry about this....

My zendto was down this morning, due to being full.  Turns out the /var/zendto/incoming was very large and had files in from January

root at zeus:/home/nads# du -h /var/zendto/incoming
28G     /var/zendto/incoming

I found an older mail list thread from June 2021 about a cron job which should exist to tidy up that directory.  I've checked and my crontab does appear to have the required entry

# Cron jobs for ZendTo to remove expired drop-offs and update usage graphs
5 0 * * * root /usr/bin/php /opt/zendto/sbin/cleanup.php /opt/zendto/config/preferences.php >/dev/null 2>&1
25 * * * * root /usr/bin/php /opt/zendto/sbin/cleanup.php /opt/zendto/config/preferences.php --no-warnings >/dev/null 2>&1
15 0 * * * root /usr/bin/php /opt/zendto/sbin/emailSummary.php /opt/zendto/config/preferences.php >/dev/null 2>&1
5 */4 * * * root find -H /var/zendto/incoming -type f -mmin +1440 -delete >/dev/null 2>&1
1 1 * * * root /usr/bin/php /opt/zendto/sbin/rrdInit.php /opt/zendto/config/preferences.php 2>&1 | /bin/grep -iv 'illegal attempt to update using time'
3 3 * * * root /usr/bin/php /opt/zendto/sbin/rrdUpdate.php /opt/zendto/config/preferences.php 2>&1 | sed '$ d' | /bin/grep -v '^[0-9]*x[0-9]*$'

Looks like the entry to tidy up /incoming is not running, but I also have blank graphs, which suggests the rrd ones might not be working either... which also make me worry about the other entries...

Is there any way I can troubleshoot these cron jobs?

Installed version is the latest I think, server was only built (in January) using the installer

Listing... Done
zendto/lynx,trusty,xenial,bionic,now 6.13-3 all [installed]

To get my space back I have run (ran?) the command from the crontab find -H /var/zendto/incoming -type f -mmin +1440 -delete >/dev/null 2>&1

root at zeus:/home/nads# du -h /var/zendto/incoming
12K     /var/zendto/incoming

And now I have plenty of space back.
