Snapraid needs a "-h" switch in the GUI

Hello fellow OMV users, good to be on board!

In regards to snapraid, there should be a -H switch, IMO, on by default.
If it's there, I didn't see it.

Basically -h is "pre-hash" it takes a short time (MUCH shorter than a post calculation verify) and is just a smart idea.
It calculates a hash, twice, before writing it to the parity data. Since most users here don't use ECC ram, as OMV is great on 'old hardware', this is a (near) sure fire way to ensure you don't store "bad parity data".

Naturally, I can jump in and triger it via command shell, but a simple tick box for "double check hash before calculating" or something, which adds a -h to the Sync command should be a thing.

Yes? no?

Do you want it added to the script, the sync button, both, or something else?

Hmm good question. I don't think it matters greatly. I'd personally say script, but the Sync button might be better suited.
You could call it "Safe Sync" or keep it program correct, and have it "Pre-Hash + Sync" as a menu option.
Or maybe even have it under configuartion?
"Always pre-hash data" as a checkbox?

Personally, even though I do use ECC ram, I'll always be using -h, so I'd love to say "add it to the script", but in reality, people might get confused as to why their Sync is suddenly taking longer.

I'm sure there are users out there who want it to finish "quicker" rather than being super paranoid about it finishing "correctly" (though I dont see the point....).

The checkbox is more work than you think. I will try to get to this sometime soon.

While I still support the check box, Is it less work in the mean time to have an extra drop down menu item? "Prehash+Sync".

As I said, we can do it in the command line for now, but I'm assuming a drop down is less work than a check box. (assuming because a check box would alter multiple scripts, where a dropdown is just a quick new script?)

You sir, deserve a cookie!
