Planning to add more cases, gradually. For example, I think inode object with RAID5 can be replicated across drives. If thats correct, can scrub fix those corruption too? cases like this may be more important than other to-do items like raid5 with features like snapshot/quota etc I think it should be possible to add test-results for few cases but list has repeated-cases with different sizes,drives etc for these cases we need some kind of automated scripts. Hope to extend the cases first and then start updating results with manual or automated tests. Cheers. Lakshmipathi.G
