Hello, I had a RAID 5 made from 3 hard disks. One of the hard disk started to have bad blocks (to fail), several weeks ago. I didn't had time to change it, until today. But from mistake, instead changing Primary Master (hda - that was failing), I've replaced the hdc (second disk in the array). After starting the system, the array tried to get online, it found the new hard disk and marked it as spare disk. I think it started to resync the information to the spare, but the failing disk had error and the array didn't got online, giving I/O error. I've seen on the screen the errors and I realized that I changed the wrong disk, so I placed the old good disk in place and placed the new disk in the bad one's place (like I had to do first time). But, the array seen the old good disk (with correct data) as spare disk, also. So, I can't bring the array online with one good remained disk and one spare. The "spare" disk, that was the good one, has the correct data information on it, only that it's seen as spare one. There is a way to make the md to see it as active disk? Modifying the super block or other way? On this array I have a lot of LVs and they contains 4 virtual machines with a lot of information on it. Can you help me with some advice?
