Prompted by a recent /. article on atime vs realtime ranting by some Linux kernel hackers (Linus included) I went back and looked at the mount_ufs(1M) man page because I was sure that OpenSolaris had more than just atime,noatime. Yep sure enough UFS has drfatime.
So that got me wondering does ZFS need drfatime or is it just not a problem because ZFS works in a different way. If ZFS did have dratime how would it impact the "always consistent on disk" requirement. One though was that the ZIL would need to be used to ensure that the writes got to disk eventually, but then that would mean we were still writing just to the ZIL instead of the dataset itself. If this is already covered somewhere please point me to the docs since I couldn't see it mentioned in anything I've read. -- Darren J Moffat _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
