vxfs is probably a completely separate fs that won't destabilize other
filesystems, or at least I hope so. ReiserFS is stable code now, we aren't
going to change that by adding features unless they go into the ac series for
six weeks or so first. ReiserFS is the SuSE recommended FS, and we can't go
destabilizing it. I am told by sistina.com (maintainers of LVM) that in their
surveys of the users of LVM, 90% use ReiserFS, and the users of LVM tend very
much to be persons with mission critical servers. We sent Linus a patch to mark
us as stable not experimental. When we say stable, it means something. Right
now it means zero (yes, zero) new bug reports that are not user error or old
versions or fsck, since 2.4.4 came out.
fsck is improving dramatically in stability every week. I used it myself last
week, and got my data back minus the root directory after trashing the front of
my partition accidentally. (Which gave me a chance to review its end user
usability, which is also improving.) We aren't yet ready to pass the zero a
random block and see it recover always excepting what was zero'd test, but we
will be before long. One of the things we realized recently is that if the user
knows what got trashed, and he can tell this to the FS, it can be very useful
for bitmap blocks. Sorry, I wander here.
