/tmp used 100% where is files?
24,280
Solution 1
You should use lsof /tmp
to see currently opened file.
If you delete a file, while a software still have a lock on it, you won't see it anymore, but it will still have hd space assigned to it.
Solution 2
That's a very small /tmp partition.
Show the output of lsof /tmp
to see which processes have open files there. Stopping the relevant process should free the space.

On Centos 6.3 server I noticed that /tmp has no longer free space to store files.
[root@]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg0-lv_root 99G 11G 84G 12% / tmpfs 16G 0 16G 0% /dev/shm /dev/sda1 194M 65M 120M 35% /boot /dev/mapper/vg0-lv_tmp 97M 92M 704K 100% /tmp /dev/mapper/vg1-lv0 50G 180M 47G 1% /mnt/ssd2
But there is nothing in /tmp at all
[root@]# ls -Sahl /tmp |more total 10K dr-xr-xr-x. 25 root root 4.0K Mar 16 04:29 .. drwxrwxrwt. 3 root root 3.0K Mar 16 03:32 . drwx------. 2 root root 1.0K Mar 16 04:28 mc-root
My question is: How could it be? By what /tmp mount space used? And how could I clean it?

Ken Tang about 11 yearsI've found apc.ini this line: ; The mktemp-style file_mask to pass to the mmap module. apc.mmap_file_mask=/tmp/apc.XXXXXX i think change this line to /var/tmp/apc.XXXXXX???

CloudWeavers about 11 yearsWhen you check the LSOF result, the 'DEL' give you an idea of which file now only exist in memory. Restarting your software stack (ie: nginx, php, etc.) should clear the HD space issues. And you are right, 100MB is not enough
