Technically it’s against the TOS, however as mentioned by someone from STORJlabs it’s ok to use less than 500GB if you have multiple nodes (although they were talking about multiple nodes with 450GB to use multiple 500GB HDDs…), so this is what you need in your config.yaml:
storage2.monitor.minimum-disk-space: 10.00 GB
I use it to “warm up” another identity so I have 2 nodes per disk so I always have a warmed up backup if one HDD dies.
Great! My old 500GB hard drive would also work well for this. Many Thanks 
I learned with such low space you can’t even get vetted fully even after 3 months, means you probably wont get vetted if you dont have enough space for the new data to come from those satellites.
yeah probably. They are both vetted on saltlake and europe-west but the rest seems to take longer. might even be up to 6 month. So I will probably have to increase to at least 250GB. But a few more months might be fine.
