Under most circumstances, verify won't hurt performance. It won't hurt reads of any kind, and it won't hurt writes when you're writing unique data, or if you're writing duplicate data which is "warm" in the read cache. It will basically hurt write performance if you are writing duplicate data, which was not read recently. This might be the case, for example, if this machine is the target for some remote machine to backup onto. The problem doesn't exist if you're copying local data, because you first read the data (now it's warm in cache) before writing it. So the verify operation is essentially zero time in that case. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
