Alright, fair enough- I rebooted the server and checked the BIOS. IDE controller #1 was set to "IDE", not AHCI. Flipped it over to AHCI, and the machine wouldn't boot. The progress bar comes up and fills twice (blue and orange), then the screen goes blank and I'm back at the POST screen. I put it back to "IDE", and the machine booted OK. I'm seeing pretty good performance from our disk backup software, but if I stop it, the scrub (which picked up where it left off) is still running at a crawl. I'm happy to switch to AHCI, so suggestions on getting the system to boot with that are welcome (does a device name need to be changed somewhere? I don't see anything obvious in /rpool/boot/grub/menu.lst, for example.) In the meantime, I'm regularly seeing iostat figures bounce between 10 and 200MB on the data pool with our backup software running, so....not sure why the scrub isn't capable of running at the same rate. If I shut down the backup software, I see figures like this: ---------- ----- ----- ----- ----- ----- ----- data 5.55T 1.70T 69 0 163K 0 rpool 18.9G 10.6G 0 0 0 0 ---------- ----- ----- ----- ----- ----- ----- Brett _______________________________________________ OpenIndiana-discuss mailing list OpenIndiana-discuss@openindiana.org http://openindiana.org/mailman/listinfo/openindiana-discuss
