Hey, before I go ahead and break things, I want to test my RAID setup and see what happens when one of the drives in a RAID1 setup gets disconnected. It's tough to do that when the computer off then on, it works no problem that way but I wanna know if it will do anything spectacular while the computer is on.

fireworks and such.

Thanks.
 
Should be fine. If you're using a BIOS fakeraid you may have to restart the machine to begin the rebuild process. I don't know if newer fakeraid products have a Windows tool but on my old system I had to rebuild from the BIOS. SATA is made to be hot-plugged.
 
Yup, SATA is hot-swap,
But I dunno if you'd want to unplug the power from the drive when the system is powered on.

The cables and connectors are physically setup for hot-swap (ground pins extend further than power/signal pins), so, you should be good to go. However, you should not expect the array to come back online if you decide to reconnect the drive.
 
Thanks. Just want to see what happens when RAID fails while in production. Is there anyway to have Linux recognize when a drive dies and notify someone via email or pager (Trixbox)?

Thanks all.
