Hi. I hope this is an appropriate forum to which to post this. We are running a AMD-64 box with Suse 9.1 and recently has a hard-reboot (plug was pulled). Upon restart, we got fdisk errors on our Volumes. Upon some prodding, we find that we are missing some physical volumes and that LVM doesn't seem to know about a few partitions. Unfortunately, we back one volume up to another and they were both hit with this problem. TIA for any hints on how to proceed - the data is a real pain to regenerate. # vgscan Couldn't find device with uuid 'Gu9G0X-wzof-x43j-VVw8-XTZ0-DSai-zCriVl'.
