 |
|
Interestingly it used to work for the root user but not anymore. It works for the user. For example, I have the following user with this crontab script which works:
| Code: |
$ crontab -l
0 */4 * * * export DISPLAY=:0; /home/mamadou/.config/i3/reddit-wallpaper.sh > /dev/null 2>&1
|
And, for the user root, I have the following:
| Code: |
crontab -l -u root
# zfs-auto-snapshot
*/15 * * * * root /usr/sbin/zfs-auto-snapshot zroot
|
Now, not only it won't work but also when I restart the dcron service I see the following in the logs:
| Code: |
May 21 01:34:11 mamadou-legion crond[6826]: /usr/sbin/crond 4.5 dillon's cron daemon, started with loglevel notice
May 21 01:34:11 mamadou-legion crond[6826]: failed parsing crontab for user root: PATH="/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"
|
Any idea where that is coming from? BTW, I did not run crontab /etc/crontab as instructed by the handbook, and have the following inside my /etc/crontab:
| Code: |
$ cat /etc/crontab
# for dcron
# dcron:
# This is NOT the system crontab! dcron does not support a system crontab.
# to get /etc/cron.{hourly|daily|weekly|montly} working with dcron run
# crontab /etc/crontab
# as root.
# NOTE: This will REPLACE root's current crontab!!
# check scripts in cron.hourly, cron.daily, cron.weekly and cron.monthly
59 * * * * rm -f /var/spool/cron/lastrun/cron.hourly
9 3 * * * rm -f /var/spool/cron/lastrun/cron.daily
19 4 * * 6 rm -f /var/spool/cron/lastrun/cron.weekly
29 5 1 * * rm -f /var/spool/cron/lastrun/cron.monthly

EDIT: I have to mention I have this issue with two separate installations. |

This
| Quote: |
*/15 * * * * root /usr/sbin/zfs-auto-snapshot zroot
|
might be ok for /etc/crontab.For the specific crontab of root it should be
| Code: |
*/15 * * * * /usr/sbin/zfs-auto-snapshot zroot
|

Thank you very much for the suggestion. I tried it:
| Code: |
$ crontab -l -u root
# zfs-auto-snapshot
*/15 * * * * /usr/sbin/zfs-auto-snapshot zroot
|
Though, still get the same error when I restart the dcron service:
| Code: |
May 21 14:05:27 mamadou-legion crond[26028]: /usr/sbin/crond 4.5 dillon's cron daemon, started with loglevel notice
May 21 14:05:27 mamadou-legion crond[26028]: failed parsing crontab for user root: PATH="/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin"

Maybe it doesnt like the comment.
Plz remove
| Code: |
# zfs-auto-snapshot
|
Also try
| Code: |
ls -l /var/spool/cron/crontabs
|
Also maybe there are hidden characters in the file.Try deleting the file and running again
crontab -e
as root.

I don't know if OP solved this issue and how, but I am seeing the same thing, user jobs are still working fine, but for some reason root jobs are not (failed parsing crontab for user root...)
It worked for ages without any issues, having trouble figuring this one out, there were no config changes or anything like that, or related updates as far as I can tell. |
