Hi list, I've got a mirror volume with two S-ATA disks, one of which started getting bad sectors recently, and I want to replace it. I'm having trouble removing it from the volume, however. When googling around on the subject, I've read everywhere that I shouldn't have to do anymore than remove it, and LVM should discover that and reconvert the mirror back into a linear volume. To be a bit more careful, though, I ran "echo 1 >/sys/block/sdh/device/delete" to have it removed properly in software first. Much to my surprise, shall we say, that just made the LV die a horrible death; it started returning EIO for every access to it, and I had to reboot the server to get it working again. Again, this is the proper procedure according to what I've been reading on the net; did I do it wrong, somehow, or are my sources completely off? (And if this doesn't work, then what would actually happen if the disk were to fail physically?) As I rebooted the server, I tried disconnecting the disk in advance, but that made LVM unable to bring the VG back online at all. How am I supposed to take this disk out of the volume? If I should use `lvconvert -m 0 $LV', then how do I specify which disk is to be removed? I'm using a stock Debian stable (Lenny) installation, meaning Linux 2.6.24 and LVM2 2.02.39.
