Hi Ivan and all=2C Yes=2C this was meant to be 2x vdevs which are striped=2C each vdev being a= 3 way mirror.=20 Yes=2C /dev/ad6.eli was a problem drive so I plugged /dev/da99.eli into the= LSI controller and=2C as you said=2C ran zpool replace vault /dev/ad6.eli = /dev/da99.eli. Then that drive failed too (coincidence?) but now I can't ge= t rid of the replacing drives. I've tried all manner of combinations of commands to remove them=2C even tr= ied finding another drive=2C changing device.hints to rename that as da99 (= which then comes up as FAULTED but the same problem as above happens).=20 Stephen - I had a look at dd'ing the drive to get enough zfs metadata out t= o trick zpool into accepting the drive and trying to resilver=2C but the pr= oblem is that the drive is too far gone - when I plug it in=2C it just comp= letely hangs the LSI controller=2C followed by screenfuls of geli errors an= d timeout errors. When I plug it into the motherboard controller=2C it does= n't even detect it properly. I can't even get to a point of being able to r= un seatools against it=2C so that drive is going to get replaced. One thing I've noticed is that the zfs implementation doesn't appear to lik= e using the degraded vdev=3B I thought it tended to favour blank drives to = even everything out but it seems to be using the full vdev where it can - i= s that purely because of the degraded vdev? If so is there anything I can d= o to restore it? I don't have enough drives to back up the pool and remake = it=2C and that's not a permanent fix anyway.
