usr/tmpdsk is huge

[Boris Horvat]

usr/tmpDSK is over 4GB but tmp folder is on 1%

that's fine. It's like an image. As large as you make it takes that much of space regardless how much of that is really being used.

can i delete it?

i found this solution... is it working?

• stop all services which uses /tmp
  service httpd stop
  service mysql stop
  service chkservd stop
• remove the tmp directory
  umount -1 / tmp
  umount -1 /var/tmp
  rm -fv /usr/tmpDSK
• recreate and secure /tmp
  edit /scripts/securetmp and change the $tmpdsksize to your chosen number of bytes (we use 20480000 = 2Gb)
  /scripts/securetmp answering yes to both questions
• restart the server
  reboot

 

[andrew.n]

You can but you will earn like 2GB extra space...is it worth it? and if you have a busy server 2GB might not be enough.
