Thanks for all the replies. When we added the two disks we changed the disk
numbering of two drives (sd4->sd6, sd5->sd7) which are neither striped nor
concatenated under DiskSuite ... but which hold three replicas on it!

This way metainit couldn't find all replicas and ejects this error message.
After deleting these replicas and creating new ones on the changed drive sd6
all goes fine. Special thanks to the guy who send me this SunSolve solution.
(I am sorry but I have delete his emailadress ..)

See the question attached.
