While doing a scrub I was getting access errors on my 1-parity drive. Short smart test was failing and I was showing sectors in Current_Pending and Offline_Uncorrectable. Following https://www.smartmontools.org/wiki/BadBlockHowto I brought those to zero but it required writing zeros to blocks in the parity file. So now I'm fixing it with snapraid -d parity fix, but the ETA is 8 hours. Is it possible to tell snapraid to fix only the blocks or sectors I wrote over or do I need to let it fix the whole...

My issue with paying for unraid has to do with the limitations that are placed on the software based on price. This is personal use, so I don't need extensive support, but I'm not a fan of restricting the software itself based on price. Yeah, charge extra for the easy gui interface, professional email or phone support, or on site service, but don't restrict the capabilities of the software. But anyway, I don't use Unraid, I prefer and I have donated to Snapraid. As I said I was just curious about...

Fair enough, but there's obviously the OS is aware of when writes to a filesystem happen, and to which file was affected. A background service could be made that would monitor those then once the file isn't accessed anymore it could update the parity on that file. Maybe not real-time, but once modifications to a file have stopped for a couple seconds. I'm not sure how hard it would be to implement on Windows due to it's proprietary nature, but with Linux, MacOS, or BSD it's probably easier I have...

I'm curious. Currently Snapraid requires that a sync be manually run to set parity. Outside of developer's time and/or skill is there any technical reason why a version of Snapraid couldn't be developed that did parity calculations on the fly? Perhaps as a background daemon or service? I realize that would eliminate the undelete feature, but perhaps the parity could be made as a two stage version with primary parity set the current way, then the on the fly parity based on the primary parity. Anyway,...

So I made a blunder with a mergerfs mount that I thought was unmounted and the mountpoint not empty. long story short, I deleted all my snapraid.content files (along with a bunch of other files) as I did not have the content files on the parity drives. So I've been trying to find a way to recover my deleted files, but without the content files, that's tough. So here's the good news, I have 15 data drives and they all had the content file on them. I also have unmounted the drives and have done nothing...
