That will also cause mysql, apache and other services to fail and stop working eventually. That’s why today we are going to show you how to re-create / rebuild corrupt /tmp partition with this quick fix.

How can I re-create or Rebuild corrupt /tmp partition?

On cPanel you can re-create and rebuild corrupt /tmp partition by following this simple steps.

1. Stop all services that are using /tmp

service httpd stop
service mysql stop
service exim stop

2. Umount /tmp partition

umount -l /var/tmp

3. Remove corrupted partition

rm -fv /usr/tmpDSK

4. Re-create the /tmp partition

/scripts/securetmp

5. Verify it is mounted properly

df -ah

You should see something like:

[root@remote.server.com:~]df -ah | grep tmp
/usr/tmpDSK     4.0G  189M  3.6G   5% /tmp
/tmp            4.0G  189M  3.6G   5% /var/tmp

6. Set write permissions

chmod 1777 /tmp -v

7. Test if you can create new files on the partition

touch /tmp/test
ls -alh /tmp/test
