Checking where space usage is:

So, I'm not sure what can be done to craerte more space here...

- Add Hours to Ticket changed from 0 to 0.25
- Total Hours changed from 0.5 to 0.75
I have stopped the Munin alerts for now by upping the alert level to 94% rather than 92% by editing /etc/munin/plugin-conf.d/munin-node:
[df*] env.warning 94 env.critical 98
Restart munin-node:
/etc/init.d/munin-node restart [ ok ] Restarting munin-node (via systemctl): munin-node.service.
I have also deleted some of the backups of the Changelog:
cd /root/.Changelog rm -f Changelog.2015* rm -f Changelog.2016-01* rm -f Changelog.2016-02* rm -f Changelog.2016-03* rm -f Changelog.2016-04* rm -f Changelog.2016-05* rm -f Changelog.2016-06* rm -f Changelog.2016-07*
And cleaned up the apt archive:
apt-get clean
And that has brought some time, the next thing to try is deleting old backups to see if that frees up space by reducing the amount of metadata stored:
df -h Filesystem Size Used Avail Use% Mounted on udev 489M 0 489M 0% /dev tmpfs 100M 5.4M 95M 6% /run /dev/mapper/CRIN3--vg-root 15G 13G 1.6G 89% / tmpfs 499M 0 499M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 499M 0 499M 0% /sys/fs/cgroup /dev/sda1 236M 195M 29M 88% /boot tmpfs 100M 0 100M 0% /run/user/1000

This came up again:
crin.org :: crin3.crin.org :: Disk usage in percent
WARNINGs: / is 97.81 (outside range [:94]).
OKs: /run is 10.34, /run/lock is 0.00, /boot is 87.07, /sys/fs/cgroup is 0.00, /dev/shm is 0.00.
But it has dropped back down now:
df -h Filesystem Size Used Avail Use% Mounted on udev 489M 0 489M 0% /dev tmpfs 100M 11M 90M 11% /run /dev/mapper/CRIN3--vg-root 15G 12G 2.4G 84% / tmpfs 499M 0 499M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 499M 0 499M 0% /sys/fs/cgroup /dev/sda1 236M 195M 29M 88% /boot crin1:/ 121G 27G 88G 24% /media/sshfs/crin1 tmpfs 100M 0 100M 0% /run/user/1000
I guess it is caused by tmp files or something, at some point we will probably have to make this server bigger.
Note: See
TracTickets for help on using
tickets.
It looks like it is because something has gone wrong with a backup job, two are running but only one s3ql filesystem is connected:
So:
This seems to be un unkillable process, rebooting the server and I'll check how it looks later.
