  1. Be careful with the parity corruption fix in KB4568831


    I think I'm my own worst enemy, wanting to get my system back to its normal state after seeing KB4568831 has this fix:


    Addresses an issue with in-memory parity bitmaps that can cause data integrity issues on Parity Storage Spaces.

    I haven't seen any corruption on my parity since there was a troubleshooter released several weeks ago. The downside of this troubleshooter is that my parity drive is no longer accessible on boot, for the first minute or so. This does cause me a few issues with apps on startup if I login too soon and they see the drive missing.

    So, with the parity fix in KB4568831, I set my parity drive back to automatically attach on startup, and I disabled the startup task that ran "C:\Windows\System32\SpacesTroubleshooter.exe".

    I used the drive for a bit like this, and I did end up seeing corruption again. Unfortunately I'm also having issues getting the troubleshooter running properly on startup again.

    I'm not sure if the new parity fix is broken, or if I'm just in a broken state due to having used the troubleshooter and then trying to go back to normal. Presumably the intention wasn't that affected parity drives always remain unavailable on boot, once the bug is fixed.

    I also haven't done a super thorough investigation yet to be 100% sure on the corruption I'm seeing, so maybe I'm mistaken and chasing ghosts here. I just wanted to post this early in case anyone else tries what I did.
