new to Linux here. Can anyone explain me how to increase the size of /tmp?

I was able to increse the size of /dev/mapper/vg00-usr, var and home , but how can I do if the /tmp folder is shown as "none". See my pic. Any help is appreciated!

    That looks like the output of the df command. What does mount output? (I'm looking for /tmp's filesystem type.) – thb Apr 2 '12 at 3:24

CentOS use tmpfs for /tmp. Check your /etc/fstab for a line like this :

tmpfs /tmp tmpfs size=4g 0 0

and change the size accordingly.

I was looking for this info for debian and found this thread after some more digging I just found the solution, just to note how it works here. To use disk instead of ram for tmpsfs edit /etc/default/rcS and set this:

RAMTMP=no

To increase the size of tmp there's another file (/etc/default/tmpfs) you can use

TMP_SIZE=2G

Part of this information have been extracted from here
