I didn't see any hard drive i/o errors but of the 'sd' device itself. I rebooted and went into the card's bios, and in there it crashed with a parity error. Bought a used card off ebay, drove there and back to replace it, and it resync'd the array (raid-1 that is..) and we're up and running. So, do you have another raid card? -eric wood -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
