Thank you, I have had this Unraid server since 2011 and never knew there was a repair tool. Where is it located in the webgui? Also is this not in the Unraid manual? I have read the manual several times and haven't seen this info in there? If its not maybe we could get it added? I feel like this could help other people with the same issue.
I am not blaming Unraid, its a great OS that I have used for some time now. I am not that upset about the data loss either. I have everything I really care about backed up in two other places. Its mostly just annoying. On the hardware issue, yes I actually do weekly parity checks and there are never sync errors. I don't think its a RAM issue, I mean I guess its possible but it seems like a small possibility. I will do a memtest just to be sure. What I am leaning towards is just old drives. I know it seems silly, but they were all 4+ year old Seagate 2TB drives probably from the same batch. I still have one left so I guess I will see...
