What is the number returned from this command?

Code: Select all

find /root/Mail | wc -l

[ahoff]

root@b3:~# find /root/Mail | wc -l
596048
root@b3:~#

This is a known annoyance. To make things more complex you cannot delete 500000 with a simple 'rm -f /root/Mail'

The rpblem is you have a process that keeps on emailing you because something went wrong. You need to find out what that process is or else you'll see the same issue again next month

If you type

Code: Select all

mail

you go to roots mailbox and you can read which process is misbehaving.

To remove all e mails, imo the simplest solution is

Code: Select all

cd /root
mv Mail Mail-ori
mkdir Mail
rm -rf /root/Mail-ori

You wont throw awat any important emails

[ahoff]

root@b3:~# mail
temporary mail message file: Enheten är full


mv Mail Mail-ori
root@b3:~# ls
bubba-horde bubba-notify Mail-orig
root@b3:~# rm -rf /root/Mail-ori

root@b3:~# mkdir Mail
mkdir: kan inte skapa katalog "Mail": Enheten är full

I seam to be in som kind of catch-22

[ahoff]

I remove them litle by litle...

root@b3:~/Mail-orig/new# rm -f 134189544*
root@b3:~/Mail-orig/new# rm -f 13471554*
root@b3:~/Mail-orig/new# rm -f 134715*
root@b3:~/Mail-orig/new# rm -f 13471*
root@b3:~/Mail-orig/new# rm -f 1347*
root@b3:~/Mail-orig/new# rm -f 134*

Thank you

It did not work because you made a typo between orig and ori. But good that you cleaned up. Now find out what is causing this misery

I don't know if the Excito guys fixed this, but running `mail` command says there's no mail on my B3. This is because the MAIL environment setting is wrong (it's pointing at /var/mail/root). To run mail you should enter the following command:

Code: Select all

MAIL=/root/MAIL/  mail

Obviously with 500.000+ emails you won't like what you'll see and it will be very hard to figure out what is important. With that many emails you can be assured however that the offending process will keep on sending these messages and it will be safe enough to delete all the old messages without reading them.

If you want an easier way to read/sort/organize the emails I recommend that you add an alias for root to admin. You can then use your preferred email application to log on to admin's mailbox (I use Thunderbird myself but many others will also allow you to configure multiple mailboxes). An added bonus is that the Storage partition where admin's home folder is located is less vulnerable to the issue.

I had 3 cronjobs runing that coused the whole thing. It's been taken care of by adding >/dev/null 2>&1 in crontab like this:

Code: Select all

# m h  dom mon dow   command
*/2.5 * * * *           /home/ahoff/bin/get_temp.sh >/dev/null 2>&1
*/2.5 * * * *           export LANG=sv_SE.utf8 && /home/ahoff/bin/graph_temp.pl >/dev/null 2>&1
*/2.5 * * * *           /home/ahoff/bin/graph_el.sh >/dev/null 2>&1

Now no more mail .

Tanks for the tip.

I wouldn't threaten with tanks for such good piece of advice!
