Hello, Thank you for the answer. Now I am sure that data corruption is related to dm-crypt. I have a few questions: Could you please let me know if bug fix in kernel 2.6.19 to dm-crypt over RAID5 is also related to RAID0? Generally from which kernel version it is safe to use dm-crypt over RAID? Thanks again very much Bruce - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
