Enable AutoPruning in Pharos Node

This guide describes how to enable automatic data pruning on your Pharos node to manage disk space.

---

For v0.11+ Deployment (New Structure)

If you deployed your node using the v0.11 deployment guide (Binary or Docker with the new structure), follow these steps.

Step 1: Verify Node Status

Check if the node is running:

curl -X POST -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' \
  http://localhost:18100

Step 2: Enable Pruning

For Binary Deployment:

cd /data/$WORKSPACE/bin
./pharos_cli prune --c ../pharos.conf --enable_auto_prune

For Docker Deployment:

docker exec -it pharos-node /bin/bash
cd /data/bin
./pharos_cli prune --c ../pharos.conf --enable_auto_prune

Step 3: Query Pruning Settings (Optional)

For Binary Deployment:

cd /data/$WORKSPACE/bin
./pharos_cli prune --c ../pharos.conf --get

For Docker Deployment:

docker exec -it pharos-node /bin/bash
cd /data/bin
./pharos_cli prune --c ../pharos.conf --get

Expected output:

PruneInfo:
enable_auto_prune: 1
auto_prune_reserved_window: 100000
prune_reserved_version: xxxxxx
flushed_version: xxxxxx
real_prune_reserved_version: xxxxxxx

If enable_auto_prune is 1, auto pruning is enabled.

---

For Legacy Deployment (Pre-v0.11)

If you deployed your node using the old Python ops tool, follow these steps.

Step 1: Verify Node Status

curl 127.0.0.1:18100/ \
  -X POST \
  -H "Content-Type: application/json" \
  --data '{"method":"eth_blockNumber","params":[],"id":1,"jsonrpc":"2.0"}'

Step 2: Enable Pruning

Enter the container and enable auto-pruning:

docker exec -it pharos-testnet /bin/bash
cd /data/pharos-node/domain/client/bin/
./pharos_cli prune --enable_auto_prune

Step 3: Query Pruning Settings (Optional)

docker exec -it pharos-testnet /bin/bash
cd /data/pharos-node/domain/client/bin/
./pharos_cli prune --get

Expected output:

PruneInfo:
enable_auto_prune: 1
auto_prune_reserved_window: 100000
prune_reserved_version: xxxxxx
flushed_version: xxxxxx
real_prune_reserved_version: xxxxxxx

If enable_auto_prune is 1, auto pruning is enabled.
