I'll dd the whole disk tonight. I was thinking it was bad spots, given how some files I can copy (admittedly they are small ones) better then others.... but in saying that, seeing the throughput at 349k/sec often is rather odd on different files. And then the files that manage to copy ok, the throughput is still stop/start all the way...the speed comes in bursts, then stops, then starts. So thinking bad sectors is the reason why I ran the Samsung diags on the drive (non-destructive) and it scanned the entire surface with no problems..
A naive question for the gurus - how about using format/analyze in non-destructive mode to look at suspect disks? It seems to me that it would be a bit harder on the disk than plain dd... Even if the disk wasn't fully dedicated to Solaris, it would exercise the bit that ZFS is using. We routinely run format/ana on all new disks before putting them in service and I was wondering if that was a waste of time.
