Are you mounting the device within dom0 after creating the domU? I'm not sure there's anything Xend can do about that. Regards, James Harper wrote: My disks line is: disk = [ 'phy:vg00/mail,0301,w', 'phy:vg00/mail-swap,0302,w' ] The unpriv domain is up and running again, although I don't know what damage has been done. /etc/passwd was missing though which is not a good sign. I found it in /lost+found, but who knows what else is missing!

Would that cause a filesystem crash, or at least errors? Dom0 wasn't doing anything to the filesystem, and the unpriv domain had been up for a few weeks before this occurred.Mounting an ext3 file system writeable in two domains is almostcertainto destroy it. The tools try and prevent this. Was it a 'file:' vbd? There'scurrentlyno safety checks for those, but there should be for physical partition and LVM volumes. IanAnyway, I've done this a few times before by mistake - made a few changes to the unpriv domain's filesystem from dom0 and forgot to unmount it before starting the domain. Is there any easy way to get 'xm create' to check before starting that none of the block devices itisabout to export are in use? Such a thing would probably save me countless headaches in the future! (or maybe it's been done already? I'm running 2.0.1) Thanks James ------------------------------------------------------- The SF.Net email is sponsored by: Beat the post-holiday blues Get a FREE limited edition SourceForge.net t-shirt from ThinkGeek.
