johnsanc Posted May 30, 2020 Share Posted May 30, 2020 I feel like this is newbie question for someone who has used Unraid for so long... but here it goes: In a dual parity setup, I noticed that when you are syncing parity for Parity #2, there are also reads for Parity #1. What is happening? Is there actually a parity check occurring for Parity #1 while Parity #2 is syncing? The Unraid UI doesn't indicate that anything is happening to Parity #1. It just says a Parity Sync is occurring in general. Quote Link to comment

johnsanc Posted May 30, 2020 Author Share Posted May 30, 2020 (edited) Cool thanks for confirming. I was planning on doing a correcting parity check just to make sure everything was synced up properly across both parity disks, but if its doing it automatically during the sync I'll just skip that. This is kind of an edge case, but it would be nice if the Unraid UI were a bit more clear about what is occurring. Generally "syncs" and "checks" are viewed as completely separate processes.
