What is PoolHD?
PoolHD is an open-source web application designed for monitoring and managing storage pools and disks. It works by connecting to the underlying storage mechanisms like ZFS, Btrfs, Linux MD-RAID to provide insights into disk health, usage statistics, performance data and more.
Some key features of PoolHD include:
- Web-based dashboard showing health overview of all pools and disks.
- Historical graphs and statistics on capacity usage, read/write ops, latency, IOPS, etc.
- Notifications for disks at risk of failing.
- Supports most major storage pool types - ZFS, Btrfs, MD-RAID.
- Lists disk details like SMART attributes to gauge disk health.
- Per pool usage statistics broken down by dataset or filesystem.
- Open source software written in Golang and Vue.js. Easy to self-host and customize.
In summary, PoolHD aims to provide an easy way to manage storage by exposing low-level details through a clean and modern web interface. It can help monitor disk health, catch issues early, visualize pool usage and performance over time - ultimately making ZFS, Btrfs and MD-RAID storage very easy to manage.
