System volume 'root' usage is 81%
Hi guys,
I've got a root volume issue and have found the culprit (I think).
# df -h Filesystem Size Used Avail Use% Mounted on tmpfs 10M 4.0K 10M 1% /dev /dev/md0 4.0G 3.3G 393M 90% / tmpfs 2.0G 4.0K 2.0G 1% /dev/shm tmpfs 2.0G 3.8M 2.0G 1% /run tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup tmpfs 2.0G 0 2.0G 0% /media /dev/md127 7.3T 6.1T 1.3T 83% /data /dev/md127 7.3T 6.1T 1.3T 83% /home /dev/md127 7.3T 6.1T 1.3T 83% /apps /dev/md127 7.3T 6.1T 1.3T 83% /var/ftp/media
# du -csh /var/* --exclude ftp 0 /var/agentx 77M /var/backups 53M /var/cache 1.6G /var/cores 50M /var/lib 0 /var/local 4.0K /var/lock 45M /var/log 0 /var/mail 8.0K /var/netatalk 0 /var/opt 3.5M /var/readynasd 4.0K /var/run 8.0K /var/spool 0 /var/tmp 4.0K /var/www 1.9G total
So it seems that /var/cores is the problem.
/var/cores# ls -All -h total 1.6G -rw------- 1 root root 1.6G Apr 16 19:40 core-java -rw------- 1 root root 2.9M Apr 25 2015 core-mc -rw------- 1 root root 186M Nov 22 2014 core-readynasd
Not sure why but since yesterday there is a 1.6GB core-java in the cores folder.
Can I delete / move it?
Thanks
Andy
When a service crashes it can leave a core dump. Analysing the core dump can be useful for determining the cause of the problem. So you may prefer to move those to your data volume rather than delete them.
You can delete/move a core dump. The core dump for readynasd from 2014 is very old and unless you are still having issues with the management service you should be able to delete that.

Back down to 45%.
