I have a strange problem for which I wasn'table to find any help so far. I am running a website on a Ubuntu 14.10 Root Server. The website uses Smarty (www.smarty.net) for caching. The website is pretty big so after three days the cache directory grows bigger than 50GB which would be normal. The problem can be described as follows:
- After three days uptime the system is down due to the Cache system being unable to write any more cache files
Disk usage shows NO full partition whatsoever:
df -Th Filesystem Type Size Used Avail Use% Mounted on /dev/mapper/vg0-root ext4 99G 2.7G 91G 3% / none tmpfs 4.0K 0 4.0K 0% /sys/fs/cgroup udev devtmpfs 32G 4.0K 32G 1% /dev tmpfs tmpfs 6.3G 860K 6.3G 1% /run none tmpfs 5.0M 0 5.0M 0% /run/lock none tmpfs 32G 0 32G 0% /run/shm none tmpfs 100M 0 100M 0% /run/user /dev/mapper/vg0-tmp reiserfs 50G 33M 50G 1% /tmp /dev/md0 ext3 992M 40M 901M 5% /boot /dev/mapper/vg0-home ext4 50G 21G 26G 46% /home /dev/mapper/vg0-var ext4 220G 85G 124G 41% /var
The website is stored in /var which is only full 41%
- If I delete any files in /var (I am not deleting Cache files so file permissions are not the problem) the system is up and running again
There must be some quota reached as deleting arbitrary files is solving the problem. My question is if anybody knows about default directory quotas in Ubuntu and how I could determine if there is any quota reached. Of course the final solution would be to remove that quota and allow using the remaining 60% space in that partition.
Any help would be highly appreciated. Thanks Martin
