Hi, even if it's not the inodes, it might be any kind of metadata (ownership, time, access rights, etc). I could for example imagine that the LVM snapshot is readonly, which would make rdiff-backup consider that there is a change, as Leland already stated.
Mounting a filesystem read-only does _not_ change the permissions that are seen for the individual files. The open() for writing is blocked by the read-only filesystem before ever getting to the point of checking the file permissions. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
