- Change SQLite journal mode from DELETE to WAL for better concurrency - Add chattr +C to /var/lib/aitbc in setup.sh to disable Btrfs Copy-on-Write - Add fallback logging when chattr is unavailable or fails - Prevent SQLite corruption on Btrfs filesystems by ensuring overwrite-in-place behavior

SSH Access Patterns for AITBC Nodes
Purpose
Document SSH access patterns for all AITBC nodes in the infrastructure.
Node Access Patterns
aitbc (localhost)
Direct access - no SSH required.
# Run commands directly on localhost
echo "command"
systemctl restart service-name
aitbc1
Direct SSH access.
ssh aitbc1
# Or execute single command
ssh aitbc1 "command"
gitea-runner (also hosts aitbc2)
Direct SSH access. aitbc2 blockchain node runs on the same host.
ssh gitea-runner
# Or execute single command
ssh gitea-runner "command"
Common Operations
Check service status on aitbc1
ssh aitbc1 "systemctl status aitbc-blockchain-node --no-pager"
Restart service on gitea-runner (aitbc2)
ssh gitea-runner "systemctl restart aitbc-blockchain-node"
Copy file to aitbc1
scp /path/to/file aitbc1:/path/to/destination
Execute script on gitea-runner
ssh gitea-runner "bash /path/to/script.sh"
Multi-Node Operations
Run command on all remote nodes
for node in aitbc1 gitea-runner; do
ssh "$node" "systemctl status aitbc-blockchain-node --no-pager"
done
Check block heights across all nodes
for node in aitbc1 gitea-runner; do
echo "=== $node ==="
ssh "$node" "curl -s http://localhost:8006/rpc/bestBlock | jq '.height'"
done
