Perhaps this is related? http://hub.opensolaris.org/bin/view/Community+Group+zfs/11 Zpool version 11, introduced "improved scrub performance" > Hello, I'm trying to figure out why I'm getting about 10MB/s scrubs, on > a pool where I can easily get 100MB/s. It's 4x 1TB SATA2 (nv_sata), > raidz. Athlon64 with 8GB RAM. With sata disks, I expect approx 500Mbit/sec per disk for sustainable sequential operations. So I would agree you should easily be able to do 100MB/s = 800Mbit/sec. You should actually be able to do something around 2x that. I don't know why your scrub is slow. Perhaps if you sit and watch it longer, you'll see sometimes it's high and sometimes it's low? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
