Step-by-Step Solution
Solution:
Step 1: Understand alarm thresholds effect
Higher vm_memory_high_watermark.absolute allows more memory usage before alarm (triggers later); lower disk_free_limit.absolute triggers only when free space is critically low (triggers later).Step 2: Prevent premature blocking
Set vm_memory_high_watermark.absolute high (allow more memory use) and disk_free_limit.absolute low (block only when disk really low).Final Answer:
Set vm_memory_high_watermark.absolute high and disk_free_limit.absolute low -> Option BQuick Check:
Memory high, disk low prevents premature blocking [OK]
Quick Trick: Balance thresholds: memory high, disk low to avoid early blocks [OK]
Common Mistakes:
MISTAKES- Disabling alarms completely
- Setting both thresholds too low
