Hey @Willem520, would you mind to share the values you have at `<alphaurl:8080>/state`? Just to confirm if its a bug in Ratel or not.

Cheers.

Thanks for the info @Willem520

Yep, that feels like a bug.  
It is not in Ratel tho.

Maybe this is the “available space” instead? @paulftw @Paras. @ibrahim

This looks like a bug. @Willem520 can you check how big are the `.sst` files in your `p` directory (this is the directory used while starting alpha `dgraph alpha -p $dir`). What’s the biggest SST file you have in your `p` directory?

There’s something wrong with the tablet size calculation. @Willem520 can you please create an issue on [Issues · dgraph-io/dgraph · GitHub](https://github.com/dgraph-io/dgraph/issues) with all the information you have? I’ll investigate this issue.
