# Quota Surge Issue Resolution
|
||
|
||
## Issue
|
||
|
||
**Error**: Insufficient vCPU quota (0 available, need 2)
|
||
- **Root Cause**: AKS surge nodes consume quota during node pool creation
|
||
- **Standard_B2s**: Needs 2 vCPUs for node + 1 vCPU for surge = 3 vCPUs total during creation
|
||
- **Available**: 4 vCPUs (should be enough, but surge consumes extra)
|
||
|
||
## Solution Applied
|
||
|
||
### Use maxUnavailable Instead of maxSurge
|
||
```hcl
|
||
upgrade_settings {
|
||
max_surge = "0" # No surge nodes, prevents quota consumption
|
||
}
|
||
```
|
||
|
||
### Benefits
|
||
- **No surge nodes**: Eliminates extra quota consumption
|
||
- **Deployment uses existing nodes**: No additional quota needed during creation
|
||
- **Fits quota**: 2 vCPUs needed (within 4 available)
|
||
|
||
## Configuration
|
||
|
||
### Validator Node Pool
|
||
- **Count**: 1 node
|
||
- **VM Size**: Standard_B2s (2 vCPUs, 4GB RAM)
|
||
- **Surge**: 0 (max_surge = 0)
|
||
- **Total vCPUs**: 2 (no surge overhead)
|
||
|
||
### Resource Allocation
|
||
- **System**: 3 × Standard_D2s_v3 = 6 vCPUs
|
||
- **Validators**: 1 × Standard_B2s = 2 vCPUs
|
||
- **Total**: 8 vCPUs (within 10 limit) ✅
|
||
|
||
## Alternative Solutions
|
||
|
||
### Option 1: Wait for Quota to Clear
|
||
- If temporary quota hold, wait and retry
|
||
- Check for ongoing deployments consuming quota
|
||
|
||
### Option 2: Request Quota Increase
|
||
- Request 2 more vCPUs (total 12)
|
||
- Allows surge nodes and more flexibility
|
||
|
||
### Option 3: Deploy as Pods (No New Nodes)
|
||
- Deploy Besu validators as pods on existing system nodes
|
||
- No additional quota needed
|
||
- Use node selectors to prefer system nodes
