Sort of, though its not raid0. It will balance the writes across the members of its storage pools. So in your 3 disk zpool, the writes will initially be spread across all 3 members. When the zpool gets very full, writes may go to one device more than others due to space requirements. > Question2: - Since most of my file /exp/dust1 (~74% = 1 - 400MB/1500MB) > reside on /tank/mnt-pt/file4, will zfs employ stripes while creating this > file? Yes and no. Some of the data will be written to other members of the zpool, but the majority of the file will be written to the newly added disk. I think that some space will be reserved for the ZIL on all members, so there would be a little less than 400 MB written to the existing members and the rest written to the new device. I did a quick search for references and could find any, so take this with a grain of salt. -B -- Brandon High [EMAIL PROTECTED] "The good is the enemy of the best." - Nietzsche _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
