UsefulScriptRepo

A collection of useful scripts for cyber security, sysadmin, and other tasks

checkMounts.py

Will detect broken or stale mounts (NFS and SMB supported) and remount the network shares, notifying via email, and ensuring log message is created.

Setup instructions (copy/pasteable)

# 1. Clone the repo (or pull updates if already cloned)
git clone https://github.com/sweets9/SweetsUsefulScripts.git /root/SweetsUsefulScripts
cd /root/SweetsUsefulScripts
git pull

# 2. Copy the script to your system path (e.g. /root/bin as custom script, only be run by root)
mkdir /root/bin 2>1 
cp checkMounts.py /root/bin/checkMounts.py
chmod +x /root/bin/checkMounts.py

# 3. Install Python dependencies 
pip install python-dotenv || apt install python3-dotenv # if required

# 4. Add to crontab for regular checks every 5 minutes
/root/bin/checkMounts.py --install

# 5. Create sentinel file to check if share is really up or not
# Note: Only run if all shares are correctly mounted and functioning otherwise will create the sentinel file in a dead path
awk '$3 ~ /nfs|cifs/ {print $2}' /etc/fstab | while read m; do mountpoint -q "$m" && touch "$m/.checkMount"; done

# 6. (Optional) Create a .env file for custom notifications
echo "SEND_NOTIFICATIONS=true
EMAIL_SERVER=mail
EMAIL_PORT=25
EMAIL_FROM=noreply@example.com
EMAIL_TO=admin@example.com " >> /root/bin/.env

# Quick Update One-Liner
cd /root/SweetsUsefulScripts && git pull && cp checkMounts.py /root/bin/checkMounts.py && chmod +x /root/bin/checkMounts.py
