Well, I'm not sure this is the best place to ask for help with hardware issues, but it does sound like a problem with at least one of your hard drives. Older raptors ran pretty hot and needed good cooling. WD's newer drives run cool. Hopefully, your raid is a mirror or a raid 5. The raid controllers built into motherboards aren't always the best way to go - how long has yours been running? Also hope you've created backup images... -----Original Message----- From: centos-virt-bounces at centos.org [mailto:centos-virt-bounces at centos.org] On Behalf Of Ben M.

Error is: "duplicate or bad block in use" Before rebooting xm dmsg had printk suppressed messages. The box is remote, 2 hour drive. Some advice on what hardware to bring with me and how to approach this via fsck would be welcome. Its an nvidia dmraid boot on WD Velocirapters. And Happy New Year to all. - Ben M. _______________________________________________ CentOS-virt mailing list CentOS-virt at centos.org http://lists.centos.org/mailman/listinfo/centos-virt __________ Information from ESET NOD32 Antivirus, version of virus signature database 4743 (20100104) __________ The message was checked by ESET NOD32 Antivirus. http://www.eset.com
