Just to clarify, I should note that in all my tests, on all my systems, I= have=20 not at any time made use of Linux Volume Management or software RAID of a= ny=20 kind. I have made use of hardware RAID in some instances, simple SCSI or= IDE=20 drives in others (and of course "poor man's RAID" in many instances, whic= h=20 basically entails a nightly, or weekly, dd of one disk to an identical=20 mirror). For this reason all of the data points (reiser's consistently unreliable=20 behavior over long periods of time, ext2 and XFS's excellent behavior, an= d=20 JFS apparently good behavior) I've provided have NOT involved interaction= =20 with LVM. Indeed, I do not even compile support for LVM into the kernel = as a=20 rule. I hesitate to spam a bunch of links here, but a simple google search on=20 Reiserfs and data corruption in both the web and news.google.com search=20 engines provide amply justification for Gentoo warning the unwary away fr= om=20 using reiser. That having been said, if people want to add some footnote= s to=20 some of those threads, and people's personal, anectdotal experiences, I d= on't=20 think that would be a bad thing at all. Removing the warning as some advocate would be, IMHO. Jean.
