I am working on adding driver for HW acc= elerated XOR engine. I am able to get XOR engine working and created AD= MA interface . I am able to create RAID-5 using mdadm. After creating f= ilesystem, I tried to mount the /dev/md0 . It failied to mount saying t= hat "ext3_check_descriptors: Block bitmap for group 384 not in group" .= For sure there is some thing wrong at driver level.=20 =A0 I used "dd" command to read/write to /dev/md0. It seems read/writes= are not a problem. When I do small file sizes of 10K , everything fine= =2E When I write a file of size of 1MB or above seems to have issue. Lo= oks like partial write fine too. =A0 I am looking for the ways to debug the problem. Also looking for su= ggestions from the people who developed HW accelerated drivers and the = issue thy run into. Are the some tools to identify the corruptions.
