Ah, okay. The slides I read said that in ZFS there is "no journal -- not needed" (slide #9):
http://www.opensolaris.org/os/community/zfs/docs/zfs_last.pdf I guess the slides are out of date in light of the "ZFS Intent Log" journal? Anyways, it all makes sense now. Without a journal, you'd need to perform the operation on slide #11 for every fsync(), which would be a major performance problem. With a journal, you don't need to do this. Great work, guys... - a -- PGP/GPG: 5C9F F366 C9CF 2145 E770 B1B8 EFB1 462D A146 C380 _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
