Hmm ... that's not what is mooted here: http://www.phoronix.com/scan.php?page=news_item&px=NzY4OQ > My understanding is it never actually got finished; and with all those > plugins it is just not possible to write a *real* fsck. I would not touch > it myself with your bargepole. It seems that it is still under development, but perhaps not as fast as it were when Hans Reiser was at it full time. I have been using reiser4 for almost a year. It *is* fast! http://www.phoronix.com/scan.php?page=article&item=reiser4_benchmarks&num=1 However, Alan's point about a <aheam!> questionable fsck.reiser4 seems correct if my experience is anything to go by: I've had a number of fs corruptions (could be dodgy hardware?) and some of them have not recovered gracefully. :-( Some data (files) were lost a couple of times. I don't know if I should blame the disk, the fs or the fsck.reiser4 command, but it is clear to me that reiser4 is not as reliable as reiserfs was for me for over 6 years. YMMV. -- Regards, Mick
