If power failure happens you will lose anything in cache. So you could lose the entire file on power failure if the system is not busy (ie ZFS does delay writes, unless you do a fsync before closing the file). I would still like to see a file system option "sync on close" or even "wait for txg on close"
Some of the best methods are to create a temp file e.g. ".download.filename" and rename when the download (or what ever) is sucessfull to "filename" Or create a extra empty file to say it has been completed e.g. filename.dn. I prefer the rename trick. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
