So have I, while using Ktorrent on one occasion and rsync to update a portage tree on the other. Both caused fairly massive filesystem corruption, i.e. 200+ files or directories being described as recoverable errors, yet they produced error messages when fsck.reiser4 was run with --fix. Then 200+ objects turned up in lost+found. I do hope this problem can be fixed because in all other features reiser4 is an _excellent_ file system. If there is anything I, as an experienced user, but not much of a programmer any more, can do please ask. Sorry, but I have not made any records of error messages. I have a spare disk on the end of a USB wire with which I am happy to experiment. -- Christopher Sawtell.
