Filesystem Forced fsck all disks.

The script does:

• Detects all ext4 filesystems (including LVM volumes)
• Forces a one-time filesystem check at next boot using tune2fs -c 1
• Ensures /etc/fstab stays exactly like it was, without changing anything
• Reboots the system with fsck forced

✅ Final Script — force_fsck_all.sh

#!/bin/bash

echo "🔍 Detecting all ext4 filesystems..."
FILESYSTEMS=$(lsblk -pn -o FSTYPE,NAME | awk '$1 == "ext4" { print $2 }')

echo
echo "🛠️  Forcing fsck on next boot for these filesystems:"
echo "$FILESYSTEMS"
echo

for FS in $FILESYSTEMS; do
    echo "→ Setting fsck trigger for $FS"
    tune2fs -c 1 "$FS"
done

echo
echo "✅ Done. /etc/fstab was not modified."

echo
read -p "⚠️  Reboot now to run fsck on next boot? (y/N): " confirm
if [[ "$confirm" =~ ^[Yy]$ ]]; then
    echo "🔁 Rebooting with forced fsck..."
    shutdown -rF now
else
    echo "❌ Reboot skipped. Run 'shutdown -rF now' manually when ready."
fi

🚀 How to Use

1. Create the script:

nano force_fsck_all.sh

Paste the script above. Save (Ctrl+O, Enter) and exit (Ctrl+X).

1. Make it executable:

chmod +x force_fsck_all.sh

1. Run it as root:

./force_fsck_all.sh

🔒 Why /etc/fstab is not modified

This version:

• Does not touch or modify /etc/fstab at all
• Assumes that your current /etc/fstab is correctly set (which it is)

That way, nothing will break, and the root fs stays set to 1, exactly as Proxmox originally configured it.
