yeah_mike Posted July 4 Share Posted July 4 I saw something on the unraid subreddit but wanted to get people's opinion here as the most upvoted comments on Reddit are often completely wrong information posted by people who don't know what they're talking about. https://www.reddit.com/r/unRAID/s/RPOzUMbCQC The reply posted by user diad6sucks here https://www.reddit.com/r/unRAID/s/rnz6vulbiA seems to indicate that in a dual parity setup you shouldn't use the array while it's being rebuilt, otherwise you risk losing data. That's wrong, isn't it? I thought the whole point of parity is that the array can remain up during the 24-36h it takes to rebuild a failed disk. Quote Link to comment

itimpi Posted July 4 Share Posted July 4 The only reason for not writing to the array during a parity operation is that both the write and parity activity badly affect each others performance while they are running in parallel. No adverse effect on data integrity. Quote Link to comment
