Before you say, DON'T DO IT THAT WAY, let me assure you that I have my reasons and I'm aware of the risks. This is mostly related to my question about changing UUIDs of physical volumes and volume groups. Anyways, I thought that perhaps I could try to use hexedit to modify the UUID within the image file. However, after I did this I ran into all the lvm commands complaining about checksum errors in the metadata. So my question is, where is the checksum stored and how is it calculated. I noticed that there is an "LVM header near the beginning of the disk followed by a long string: LABELONE........?... ...LVM2 001M0U7CEZK8M7l2Z4KnOtI1uSVjAu0cCFd Is that last part the checksum? What kind is it? -- Mark S.
