I found out that the spare disk replaces the old disk transparantly, after it syncs. However, I also found out that one of my harddrives had bad sectors! ( :( :( ). And it wasn't the spare disk either. So I had to not sync (because trying to read the bad sectors would cause that device to fail, bringing the whole array down). Instead I just mounted ro, and copied the most important bits out (well the ones that would fit on my sytem drive), then ran a badblock program that I got from the manufacturer's site to "remove" the badblocks (that is, hide them). And finally rebuilt the array from scratch. The only lucky thing was that I still had the old array available, just not onsite. So after procuring it and copying it back onto the new array (along with the saved bits) I've lost only about 10% of my data. -Gryn (Adam Luter) - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
