I've just set up Swarm. It's amazing.

My domain names now serve swarm pages.

The purpose of my server is to be a gateway that serves pages and do nothing else.

So how can I prevent my server from eating up disk space? (i.e. run Swarm in a mode that it doesn't write anything)

So how can I prevent my server from eating up disk space?

There is a JSON configuration file in your bzz directory. You can set the two relevant storage capacity options to a custom value.

You find this in the relevant section of the swarm guide

Note: Zero memory cache size (CacheCapacity) is not going to work. Set that to at least a decent value of a few hundred.

(i.e. run Swarm in a mode that it doesn't write anything)

It's not a good idea to not write anything. You can set DbCapacity to an acceptable value c (then the disk space used by Swarm is estimated at roughly c * 4Kb with some added O(logn) overhead). Using c = 5000 will take up roughly 25Mb on disk.

  • Dude, that's really really helpful. Thanks. In the time it took to check back here, I hacked it by creating a pseudo-partition. sudo mkdir /bzz #mount point for the img sudo chown eamorr:eamorr /bzz sudo dd if=/dev/zero of=/bzz.img bs=1 count=0 seek=1G ls -altr /bzz.img sudo mkfs /bzz.img sudo mount -o loop /bzz.img /bzz #Add to fstab: /bzz.img /bzz ext4 loop 0 0
