This has already been discussed in this thread. The threading model doesn't affect the outcome of files being fragmented or unfragmented on disk. The OS is smart enough to know "these blocks writen by process A are all sequential, and those blocks all written by process B are also sequential, but separate." _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
