You probably guessed that no matter what I did, I never, ever saw the problem when your trace was installed. I'd guess at some obscure timing-related problem. I can still trigger it consistently with a vanilla 2.6.17_SMP though, but again only when bitmaps are turned on. Neil Brown wrote: O

Hello, I'm trying to rebuild a raid1 array by adding the replacement disk (sda) to the old one (sdf). I zero'd the new disk (sda) and created the partition table corresponding to the existing one. I adapted my raidtab to the new drive node (changed due to other disk replacement) and now I'm
