Well, finally the reshaping of the RAID on the home server is ready. Took about 34 hours. But now the damaged RAID-10 has been converted to a fresh and well-active RAID-5. The server cabinet is screwed shut and (carefully!) put in place in the cupboard. As a server, it is less powerful than before, it has less memory and one less hard drive. But in hindsight, the old server was a bit overkill, and this one will do just fine.

I just need to put a few gigabytes of files in their proper place. When trying to extract data from a broken RAID I also gave a stupid command. Fortunately, ReiserFS is quite capable of undeleting files. But the dots still have to be put on the i!
