# Indri Maintenance Log
|
|
|
|
Indri is a Mac Mini M1 (2020) serving as the primary [[1767747119-YCPO|BlumeOps]] server.
|
|
|
|
## Host Details
|
|
|
|
- Model: Mac mini M1, 2020 (Macmini9,1)
|
|
- Storage: 2TB internal SSD
|
|
- macOS: 15.7.3 (Sequoia)
|
|
- Role: Primary server for homelab services
|
|
|
|
## Passwordless Sudo
|
|
|
|
Configured passwordless sudo for `erichblume` user to allow ansible `become: true` tasks to run without password prompts:
|
|
|
|
```bash
|
|
# Config at /etc/sudoers.d/erichblume
|
|
erichblume ALL=(ALL) NOPASSWD: ALL
|
|
```
|
|
|
|
This is acceptable given the security model - tailnet access is the trust boundary.
|
|
|
|
## Sleep Prevention
|
|
|
|
Indri must stay awake to serve network requests. Currently using **Amphetamine** (App Store) to prevent sleep.
|
|
|
|
**Configuration:**
|
|
- Start Session At Launch: enabled
|
|
- Default Duration: indefinite
|
|
- Allow Closed-Display Sleep: enabled (no display attached)
|
|
|
|
**Known Issue:** Amphetamine can crash after extended uptime (~12 days observed), leaving the system unprotected. If this becomes a recurring problem, consider switching to system-level sleep prevention:
|
|
|
|
```bash
|
|
# Option 1: Disable sleep via pmset (requires sudo)
|
|
sudo pmset -c sleep 0 displaysleep 0
|
|
|
|
# Option 2: Use caffeinate daemon via LaunchAgent
|
|
# Create ~/Library/LaunchAgents/com.local.caffeinate.plist
|
|
caffeinate -s # -s = prevent sleep on AC power
|
|
```
|
|
|
|
These could be managed via ansible for reliability.

## Log
|
|
|
|
### Mon Jan 20 2026
|
|
|
|
**Amphetamine crash caused overnight sleep**
|
|
|
|
- Amphetamine 5.3.2 crashed at 19:08 on Jan 19 (segfault in `objc_release` during timer callback)
|
|
- System went to sleep at 19:20, stayed asleep overnight
|
|
- Discovered when services were unreachable; manually restarted Amphetamine at ~07:30
|
|
- Crash report: `~/Library/Logs/DiagnosticReports/Amphetamine-2026-01-19-190921.ips`
|
|
- Root cause: Memory management bug in Amphetamine during long-running session (~12 days uptime)
|
|
- Action: Monitoring for now; if recurs, will implement `pmset`/`caffeinate` via ansible
