Oracle DR: Complete Phase 5 - NFS mount point configuration

Phase 5 implementation completed: - NFS server installed on Proxmox (nfs-kernel-server) - NFS export configured: /mnt/pve/oracle-backups → VM 109 - Windows NFS Client enabled in VM 109 - F:\ drive auto-mount at startup via scheduled task - PowerShell script: D:\Oracle\Scripts\mount-nfs.bat - Directory permissions set to 777 for Windows compatibility - Mount persists across VM reboots Files updated: - DR_UPGRADE_TO_CUMULATIVE_PLAN.md: Status → Phases 1-3-5 COMPLETED - Added detailed Phase 5 documentation with step-by-step setup - Updated validation checklist (8 items completed) Next: Phases 4, 6, 7 (scheduled tasks, restore script, testing) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

-### PHASE 5: Update DR Restore Script (30 minutes)
+### PHASE 5: Configure NFS Mount Point on VM 109 (30 minutes) ✅ COMPLETED

-**Objective:** Update restore script to read backups from mount point (E:\) and handle cumulative backups
+**Objective:** Mount Proxmox backup storage as F:\ drive in Windows VM using NFS

-#### 5.1 Modifică scriptul de restore existent pentru cumulative backups
+**Status:** ✅ COMPLETED on 2025-10-10
+
+#### 5.1 Install and configure NFS server on Proxmox
+```bash
+# SSH to Proxmox host
+ssh root@10.0.20.202
+
+# Install NFS server
+apt install -y nfs-kernel-server
+
+# Configure NFS export
+echo '/mnt/pve/oracle-backups 10.0.20.37(rw,sync,no_subtree_check,no_root_squash)' >> /etc/exports
+
+# Apply export configuration
+exportfs -ra
+
+# Set permissions for Windows compatibility
+chmod -R 777 /mnt/pve/oracle-backups
+
+# Verify export
+showmount -e localhost
+# Expected output: /mnt/pve/oracle-backups 10.0.20.37
+```
+
+#### 5.2 Enable NFS Client in Windows VM 109
+```powershell
+# SSH to VM 109
+ssh -p 22122 romfast@10.0.20.37
+
+# Enable NFS Client feature
+Enable-WindowsOptionalFeature -Online -FeatureName ServicesForNFS-ClientOnly -All -NoRestart
+Enable-WindowsOptionalFeature -Online -FeatureName ClientForNFS-Infrastructure -All -NoRestart
+Enable-WindowsOptionalFeature -Online -FeatureName NFS-Administration -All -NoRestart
+
+# Verify installation
+Get-WindowsOptionalFeature -Online | Where-Object {$_.FeatureName -like "*NFS*"}
+```
+
+#### 5.3 Create PowerShell mount script with auto-retry
+```powershell
+# Create Scripts directory
+mkdir C:\Scripts
+
+# Create mount script
+notepad C:\Scripts\mount-nfs.ps1
+```
+
+**Content of `C:\Scripts\mount-nfs.ps1`:**
+```powershell
+Start-Sleep -Seconds 10
+
+# Wait for NFS Client service
+$timeout = 60
+$elapsed = 0
+while ($elapsed -lt $timeout) {
+    $nfsService = Get-Service | Where-Object {$_.Name -like "*NFS*" -and $_.Status -eq "Running"}
+    if ($nfsService) { break }
+    Start-Sleep -Seconds 5
+    $elapsed += 5
+}
+
+# Unmount F: if exists
+try { & umount F: 2>$null } catch {}
+
+# Mount NFS share
+Start-Sleep -Seconds 5
+& mount -o rw,nolock,mtype=hard,timeout=60 10.0.20.202:/mnt/pve/oracle-backups F:
+
+# Log result
+"$(Get-Date) - Mount completed" | Out-File C:\Scripts\mount-nfs.log -Append
+```
+
+#### 5.4 Create scheduled task for auto-mount at startup
+```cmd
+# Create scheduled task (run in CMD as Administrator)
+schtasks /create /tn "Mount NFS F" /tr "powershell.exe -ExecutionPolicy Bypass -File C:\Scripts\mount-nfs.ps1" /sc onstart /ru SYSTEM /rl HIGHEST /delay 0000:30 /f
+
+# Verify task creation
+schtasks /query /tn "Mount NFS F"
+
+# Test manual mount
+mount -o rw,nolock,mtype=hard,timeout=60 10.0.20.202:/mnt/pve/oracle-backups F:
+
+# Verify mount
+dir F:\ROA\autobackup
+```
+
+#### 5.5 Verification checklist
+- [x] NFS server running on Proxmox (port 2049)
+- [x] Export visible: `showmount -e 10.0.20.202`
+- [x] Windows NFS Client services enabled
+- [x] F:\ drive mounts successfully with manual command
+- [x] Scheduled task runs at startup
+- [x] F:\ persists after VM reboot
+- [x] Can create/read/write files on F:\ROA\autobackup
+
+**⚠️ IMPORTANT NOTES:**
+- NFS uses IP-based authentication (no username/password)
+- Only VM 109 (10.0.20.37) can access the share
+- `no_root_squash` allows Windows to write as root
+- Permissions 777 on Proxmox ensure Windows compatibility
+- Mount point is **F:\** (not E:\, which is already in use)

-3. Proxmox host: pveelite (10.0.20.202)
-4. Goal: Implement CUMULATIVE incremental backups (13:00 + 18:00) for better RPO (4-5 hours vs 24 hours)
-5. Key change: Backups stored on Proxmox host, mounted in VM 109 when needed

-**Start implementation with:**
+**What's DONE:**
+- ✅ Proxmox host storage (`/mnt/pve/oracle-backups/ROA/autobackup`)
+- ✅ NFS server on Proxmox with export for VM 109

+- ✅ F:\ drive auto-mounts at startup via scheduled task
+- ✅ Transfer scripts modified to send to Proxmox host
+- ✅ RMAN script already has CUMULATIVE keyword

 ```bash
-# Phase 1 - Proxmox host storage setup (15 min)
-ssh root@10.0.20.202
-mkdir -p /mnt/pve/oracle-backups/ROA/autobackup
-# ... follow Phase 1 steps
+# Phase 4 - Update scheduled tasks on PRIMARY (45 min)
+# 1. Setup SSH key from PRIMARY to Proxmox
+# 2. Test transfer scripts
+# 3. Create/modify scheduled tasks for 13:00 and 18:00
+
+# Phase 6 - Update DR restore script (30 min)
+# Modify restore script to use F:\ instead of local path
+
+# Phase 7 - End-to-end test (30 min)
+# Full test: backup → transfer → mount → restore
