docs: upgrade instructions for v7.4.0 - #382
Conversation
WalkthroughAdded a validator runbook for the coordinated Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The upgrade guide currently permits an unsafe repeat backup and does not reliably prevent the service from downloading and running an unexpected binary, which could lead to incorrect recovery or unintended runtime behavior. These instructions should be corrected before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 inconclusive)

| Turn off state sync for the restart. You already have halt-height state; a trust hash from a live RPC will be wrong until the network is producing again. | ||

On restart the node can drop halt-height state and sync from a dead/wrong trust_hash. Validators that already have halt-height state should apply the first block locally.
| 2. Restore data from the pre-upgrade backup you took in §3.2. Replace `data` only. Leave `config/priv_validator_key.json` and `config/node_key.json` alone. | ||
|
|
||
| ```bash | ||
| rm -rf "$DAEMON_HOME/data" | ||
| cp -a "$DAEMON_HOME/cosmovisor/backup/data-pre-v7.4.0" "$DAEMON_HOME/data" | ||
| ``` | ||
|
|
||
| If Cosmovisor wrote its own backup under `$DAEMON_HOME/cosmovisor/backup` during a failed switch, use the snapshot whose height is the halt height, not a copy taken after the failed block. | ||
|
|
||
| 3. Remove the upgrade marker so Cosmovisor / `x/upgrade` do not think the upgrade already ran. | ||
|
|
||
| ```bash | ||
| rm -f "$DAEMON_HOME/data/upgrade-info.json" | ||
| ``` | ||
|
|
||
| 4. Point `current` at `v7.4.0` again and re-check the binary. | ||
|
|
||
| ```bash | ||
| ln -sfn "$DAEMON_HOME/cosmovisor/upgrades/v7.4.0" "$DAEMON_HOME/cosmovisor/current" | ||
| "$DAEMON_HOME/cosmovisor/current/bin/kiichaind" version | ||
| sha256sum "$DAEMON_HOME/cosmovisor/current/bin/kiichaind" | ||
| ``` | ||
|
|
||
| 5. Confirm local height is the halt height, state sync is off, then start with the set again. | ||
|
|
||
| If you have no halt-height backup, do not run `unsafe-reset-all` on a validator. Ask the team for a snapshot taken at the halt height and restore that, then start `v7.4.0`. | ||
|
|
||
| A wrong **state-sync** `trust_hash` (join-script style) is a different failure: the node never had halt-height state. Fix it by disabling state sync and restoring a halt-height snapshot, not by editing `trust_hash` against a half-upgraded RPC. |

Would not a kiichaind rollback solve the problem? I'm not sure, just asking if its true

kiichaind rollback if halt+1 actually committed. Typical wrong AppHash never commits, so rollback would delete the last good block. It also doesn’t fix Cosmovisor current or upgrade-info.json.

Cosmos SDK Cosmovisor DAEMON_ALLOW_DOWNLOAD_BINARIES systemd environment official documentation
💡 Result:
In the Cosmos SDK, the DAEMON_ALLOW_DOWNLOAD_BINARIES environment variable controls whether Cosmovisor is permitted to automatically download upgrade binaries when a chain upgrade is triggered [1][2][3]. Official Guidance and Usage: - Functionality: If set to true, Cosmovisor will attempt to download the necessary binary automatically if a local binary is not found when an upgrade plan is triggered [1][2]. If set to false (the default), Cosmovisor will not attempt to download binaries, requiring administrators to manually place the upgrade binaries in the appropriate directory [1][4][5]. - Security Recommendation: Official documentation notes that this feature is primarily intended for full nodes rather than validators for security reasons [1][2][3]. - Systemd Configuration: When running Cosmovisor as a systemd service, this variable is typically defined within the [Service] block of the unit file using the Environment directive [6][5][7]. Example Systemd Configuration: [Service]... Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=true"... For further details, refer to the official Cosmos SDK documentation on Cosmovisor [1][8][4].

Set DAEMON_ALLOW_DOWNLOAD_BINARIES=false in the kiichain systemd unit.
The shell export does not affect sudo systemctl start kiichain. The linked join script sets this variable to true, so Cosmovisor can download and run a binary when the local upgrade binary is missing. Add a systemd drop-in, then reload and inspect the effective environment.

Make the halt-height backup safe to repeat.
If home-pre-v7.4.0 already exists, cp -a copies $DAEMON_HOME inside that directory. A second run therefore creates home-pre-v7.4.0/.kiichain, while Line [265] restores from home-pre-v7.4.0/data. Recovery then uses the older backup or fails instead of using the newly confirmed halt-height copy.
Stop when the destination exists and require explicit verification, or copy to a temporary path and rename it atomically.
Proposed guard
backup="$HOME/kiichain-backup/home-pre-v7.4.0"
if [ -e "$backup" ]; then
echo "Backup already exists. Verify its halt height before proceeding."
