OSM database on SSD

rw — Tue, 27 Apr 2010 14:01:19 -0400

I'm experimenting with importing the OSM database to a solid state disk. I hear they can be pretty fast. I expect it will take time to get the configuration right.

Default settings, mounted with noatime

First try it with all settings as default as possible. Mount the ssd with noatime to reduce writes to the ssd. read more »

fdisk whole disk as one partition
mke2fs -t ext3 /dev/sdd1

sudo mkdir /raid/newgis sudo chown postgres:postgres /raid/newgis

As the postgres user
sudo -u postgres -i

Create a user for this database. Perhaps replace username with your username? Sure. read more »

The OpenStreetMap database gets bigger every day. The dataset is freely licensed and available in what we call a planet file. This means that if you want the OpenStreetMap dataset, you can have it. This also means that you are dealing with the entire dataset, for the whole planet, even if your interest is limited to a smaller area. If your interest is geographically limited, pushing around 6G¹ more data than you need to push around seems wasteful. read more »
