Tezos Rolling Mode Guide (How To)

Running Tezos in this mode will only store the blocks after latest snapshot, no longer requiring hundreds of gigabytes of drive storage space.

The software modification is provided by Nomadic Labs, details: https://blog.nomadic-labs.com/introducing-snapshots-and-history-modes-for-the-tezos-node.html

Upgrade only:

rm -rf tezos
wget https://gitlab.com/nomadic-labs/tezos/-/archive/mainnet-snapshots/tezos-mainnet-snapshots.zip
unzip tezos-mainnet-snapshots.zip
cd tezos-mainnet-snapshots
git checkout mainnet
make build-deps
make

If it fails:

opam update
opam pin list -s | xargs opam pin remove
make build-deps
make

Run node, no changes for other parts:

./tezos-node run --rpc-addr 127.0.0.1:8732 `bash get_peers.sh` --history-mode rolling

Full procedure:

sudo apt install bubblewrap
sudo apt install zip
wget https://gitlab.com/nomadic-labs/tezos/-/archive/mainnet-snapshots/tezos-mainnet-snapshots.zip
unzip tezos-mainnet-snapshots.zip
cd tezos-mainnet-snapshots
git checkout mainnet
sudo apt install curl
sh <(curl -sL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh)
wget https://github.com/ocaml/ocaml/archive/4.06.1.zip
unzip 4.06.1.zip
cd ocaml-4.06.1
./configure -bindir /usr/bin -libdir /usr/lib/ocaml -mandir /usr/man/manl
make world
umask 022
sudo make install
cd
opam init

Create an identity, start RPC server, add address, activate:

./tezos-node identity generate 26


echo "curl -s 'http://api.tzscan.io/v2/network?state=running&p=0&number=50' | grep -Po '::ffff:([0-9.:]+)' | sed ':a;N;$!ba;s/\n/ /g' | sed 's/::ffff:/--peer=/g'" > get_peers.sh 

./tezos-node run --rpc-addr 127.0.0.1:8732 `bash get_peers.sh` --history-mode rolling
./tezos-client add address fundraiser <tz1...> 
./tezos-client activate fundraiser account fundraiser with <activation_key>

To import your fundraiser private key: ./tezos-client import fundraiser secret key fundraiser

Start baking (background service &), path to your node location:

./tezos-baker run with local node "/home/**user**/.tezos-node"
./tezos-endorser run "fundraiser"
./tezos-accuser run

I cannot do git checkout mainnet in the folder where I unzip the tezos-mainnet-snapshots.zip file. I get an error "fatal: not a git repository (or any parent up to mount point /home)".
any ideas?

Hey, I'm running the node by described above with rolling mode but sync started at the beginning and already use 50GB. I checked timestamp:
$ ./tezos-client get timestamp
2018–12–05T16:55:20Z
What I’m doing wrong?

Same here, seems like experimental-rolling is not working as expected yet. My node went through the complete chain from the begining.

Hi, be careful, last time I tried I could not produce blocks or endorse. This is a bit misleading. Also it stores many gigabytes anyway.
