Or am I missing something? If I understand it correctly ZFS always writes new block - no updates. It also means it should be able to write sequentially most of the time even if application is issuing random writes/updates. Of course it would be interesting to see what is going to happen after some time (months, years) and when the pool is mostly full - then perhaps it would be hard to write sequentially. Perhaps some kind of backgorung re-ordering would be helpful here (simple file rewrite should do the job - however probably something more clever will be needed). -- Best regards, Robert mailto:[EMAIL PROTECTED] http://milek.blogspot.com _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
