The script serves as a simple way to verify the ZED (ZFS Event Daemon) email notification system by simulating a scrub operation.

test-zed-notifications.sh

#!/bin/bash
# This script creates a sparse ZFS filesystem with a random pool name, scrubs it, and removes it to test ZED email notifications.

# Generate a random pool name
pool_name="test_$(date +%s | sha256sum | base64 | head -c 10)"

# Generate a random filename for the sparse file
sparse_file_path="/tmp/sparse_file_$(date +%s | sha256sum | base64 | head -c 10)"

# Create a sparse file with a size of 512MB
dd if=/dev/zero of="$sparse_file_path" bs=1 count=0 seek=512M

# Create a ZFS pool with the generated pool name using the generated sparse file as the storage device
zpool create "$pool_name" "$sparse_file_path"

# Initiate a ZFS scrub on the created pool.
# After the scrub is completed, ZED (ZFS Event Daemon) will send an email notification.
zpool scrub "$pool_name"
sleep 2

# Export (unmount) the created ZFS pool, making it no longer available
zpool export "$pool_name"

# Remove the generated sparse file to clean up
rm "$sparse_file_path"
