Hi Xiao, That particular array is super1.2. The block trace was captured on the disk underlying the partition device on which the md array member resides, not on the partition device itself. The partition starts 2048 sectors into the disk (1MB). So the 2048 sectors offset to the beginning of the partition, plus the 8 sector superblock offset for super1.2 ends up at 2056. Sorry for the confusion there. Regards, --Chris
Thanks for the explanation. I still have some questions in other emails about
your patch. Could you have a look when you are free. Regards Xiao
