Thanks for the hints, however, I can't try it anymore. The latest freeze has left my data partition with a corrupt metadata tree and -- rebuild-tree gave the filesystem it's rest. After some research on Reiser4 and the surprising twist in Hans Reiser's personal fate (he was arrested with murder charges last October), I'm having my doubts as far as further development/ bugfixing is concerned and therefore decided to switch back to ext3 before playing back the backup. http://en.wikipedia.org/wiki/Hans_reiser Cheers, -sven
