It might not qualify as "major production", but I believe there is

Log-structured file system in use today Posted Aug 21, 2006 17:01 UTC (Mon) by arjan (subscriber, #36785) [Link] there is an issue with jffs2 though.. it doesn't really scale with size. Nowadays 8 Gb of flash is not uncommon, but jffs2 just is impractical to use there. In addition, jffs2 does waste quite some space that it needs for the garbage collector to do it's work...
(and technically, jffs2 is log structured with a few twists, it's not strictly log structured, but chunked into log pieces)

Seems interesting. I like the idea of a 'lossless' file system and being able to mount snapshots of a file system at different times in it's history.

As is the original Sprite LFS, actually.
Log-structured file system in use today Posted Aug 21, 2006 20:44 UTC (Mon) by wookey (subscriber, #5501) [Link] I was about to make that point as well. There are an awful lot of production systems using JFFS2 (and a much smaller number using YAFFS(2), also log-structured). OK, it's a rubbish _disk_ filesystem but in small-system world disks are the exception rather than the rule. So I don't think 'major production' is going too far.
