Yes, it did, but I get the "D" state for processes accessing the mount,
too. The logs show messages of the type "chunk xyz has only invalid copies
(1) - please repair it manually", so I guess the metadata is still not
correct (IP addresses and names of the chunk servers haven't changed).

The biggest problem is that we cannot figure out what the RAID controller
exactly did to the file system of the master server, and we haven't found
any traces of a more recent metadata file. The metalogger system had no
problem, but can it be that the metalogger was/is out of sync due to the
silent file system corruption on the master system?

Best,
René.
