You would have to port them over yourself to build FreeBSD with them. Ext3fs is probably a good possibility for a journaling file system for FreeBSD, since it supposedly reuses a lot of the organization of ext2fs with some features added on (I don't know how well these journaling file systems perform compared to each other and nthings like ffs and I have seen conflicting results/claims). It should be easier to implement ext3fs in FreeBSD since ext2fs is already in FreeBSD. The only logging/journaling file system available for *BSD that I am aware of is LFS, which I don't think is either stable or fast. I don't know how big a filesystem FFS+softdeps will support, but soft updates is not completly stable although I think it can be used with reasonable assurance it won't explode (I have). FFS on FreeBSD can support +300GB file systems I think, but whether soft updates will work correctly (or at least as correctly as it does in smaller file systems) at these sizes is unknown to me. ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
