Meetbot is currently the largest single user of Toolforge NFS space with these two log files:
taavi@tools-sgebastion-08:/data/project/meetbot $ ls -lah meetbot.out -rw-rw---- 1 tools.meetbot tools.meetbot 250G Jun 20 13:08 meetbot.out taavi@tools-sgebastion-08:/data/project/meetbot $ ls -lah logs/messages.log -rw-r--r-- 1 tools.meetbot tools.meetbot 250G Jun 20 13:08 logs/messages.log
Most of that is complaining about disconnects from Freenode and that it can't write to /data/project/meetbot/wm-labs-meetbot.conf (somehow has mode 0400). I'm not sure if those can safely be deleted over the network or if it should be done on the NFS servers instead. I've stopped the bot to stop the growth of these log files.
