This may be an additional problem or the only problem. Metadata 0.90 is at the end of the device. Metadata 1.20 is 4k from the start of the device. The other versions are in still other places. (I have no idea what messed up process created these thorougly insane changes.) So, yes, 4k offset is right in the first key-stripe. If so, then your data is pemanently gone unless you have a header-backup. In this case it is also possible that the array actually assembled right and the problem is _only_ the new raid metadata block. Arno -- Arno Wagner, Dr. sc. techn., Dipl.
