I think it will be to others. It's a bit above my pay grade unfortunately. Doing a quick Google of RAID ext3_check_descriptors turns up others having similar issues to yours (I think) with a few posts that look like solutions, or possible solutions. IMPORTANT: My first inclination was to suggest an fsck but one post I found made it sound like that hurt his RAID so read carefully before doing anything that might cause more hard. - Mark -- 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
