Change /tmp file system from ext3 to ext4
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvde1 48G 7.3G 38G 17% /
/securetmp 962M 18M 896M 2% /tmp
Check /securetmp file type to make sure whether its ext3 or not.
# file /securetmp
/securetmp: Linux rev 1.0 ext3 filesystem data (needs journal recovery) (large files)
Then unmount /tmp
# umount /tmp
Next format /securetmp to use ext4 file system
# mkfs.ext4 /securetmp
You can verify it by running file command.
# file /securetmp
/securetmp: Linux rev 1.0 ext4 filesystem data (extents) (large files) (huge files)
Edit ext3 to ext4 for /securetmp in /etc/fstab:
# /securetmp /tmp ext3 loop,noexec,nosuid,rw 0 0 ====> /securetmp /tmp ext4 loop,noexec,nosuid,rw 0 0
Run mount -a to get fstab updated
# mount -a
Thats it. We're done.
