GeoNode and /tmp

I noticed that when you use the web browser to load layers into GeoNode, the data gets stored and uncompressed in /tmp.   This is a problem, since the ODroid C2 has 16GB eMMC.   Fortunately, the C2 can run both eMMC and SD Card storage simultaneous.

I added a 32 GB SD Card to the ODroid C2 that was hosting GeoNode.  Here are the steps to do this:

su root

Use fdisk to list the devices:

fdisk -l

Create new partition with the device id that belongs to the SD Card:

fdisk /dev/mmcblk1

Create new primary partition, use default settings

Format the new partition:

mkfs.ext4 /dev/mmcblk1p1

Automount the new partition by editing  /etc/fstab

Add line:

/dev/mmcblk1p1 /tmp ext4 defaults 0 0

Allow read/write access

chmod 777 /tmp

Reboot and you should see GeoNode start using the new /tmp directory.  You can check by running this command:

df -h

This will also need to be done to accommodate the geonode data directories.  This will be done in a further blog post.
