Feature request: build-in support for snapRAID

[tomillr]

Coming from OpenMediaVault, the main thing I'm missing is support for snapRAID, as an user friendly solution for storage parity, backups and protection against bit rod.

See the official comparison charts for all the possible benefits snapRAID would bring to CasaOS users:

OpenMediaVault has a nice plugin, that allows snapRAID be controlled over the GUI instead of the terminal. Maybe the plugin could acts as a base for integrating snapRAID into CasaOS?

Here's a quick overview of the main features of snapRAID:

SnapRAID is a backup program designed for disk arrays, storing parity information for data recovery in the event of up to six disk failures.

• You can utilize disks already filled with files without the need to reformat them, accessing them as usual.
• All your data is hashed to ensure data integrity and prevent silent corruption.
• When the number of failed disks exceeds the parity count, data loss is confined to the affected disks; data on other disks remains accessible.
• If you accidentally delete files on a disk, recovery is possible.
• Disks can have different sizes.
• You can add disks at any time.
• SnapRAID doesn't lock in your data; you can stop using it anytime without reformatting or moving data.
• To access a file, only a single disk needs to spin, saving power and reducing noise.

Just noticed that CasaOS already uses mergerFS in the background:

The combination of mergerFS and snapRAID is used by many users of OpenMediaVault to replicate some of the core functionality of Unraid. With mergerFS already being used in CasaOS, adding snapRAID would be the perfect complement.

The secret sauce behind the popularity of NAS OS giants like Synology and Unraid? Their flexible mixed drive RAID. Easy expansion and drive swaps are huge wins for homelabs and small businesses.

With Synology's brand-specific drive policy and Unraid's rising licensing costs, the stage is set for a new contender. CasaOS, are you ready to seize the moment? Implementing robust mixed drive RAID could be the killer feature that makes you the go-to open-source NAS solution. Let's make storage upgrades and replacements a breeze! CasaOS when is the next upgrade coming.
