Increase /tmp

[RAH]

Hello,

What is the easiest way to increase the size of /tmp on a CentOS 5 server? I have done this before but forget how.

Thanks.

If /tmp is a partition, you can use the PartedMagic LiveCD to easily increase the size of the partition.

Note that you'll need unallocated space adjacent to it in order to increase the partition size, so you can use the livecd to shrink one of the other partitions if need be in order to get the unallocated space.

How do I know if /tmp is a partition? Also I can't use a livecd, it's a remote server.

you can check if /tmp is a partition by running mount without parameters.

mount

this will show you the partition mounted as /tmp.

for a remote server i dont think of any trivial way to shrink a partition(if you are not using LVM). what i would do is to make a PXE server locally , put the Live CD in the PXE server. then i point the remote server back to the local one and boot with the Live CD (over PXE) and i shrink the partition.
NOTE - to do this you need a console login and root permission on the remote server and of course the remote server is in your dhcp range. this is not trivial as i said above AND I WOULD NOT DO IT ON A PRODUCTION SYSTEM(you've been warned).
