It just have way to many bad blocks to be useful so I took it out of service (but, unfortunately not from the machine - I'll remember to do that next time :)...

I saw that in the same instant it was sent, but to late to cancel... I've had quite a lot of time thinking about this, and I am now QUITE sure that I created the array with 'missing' on the place where this disk should have been.... I can VAGLEY remember that that disk kept failing the array when I built the machine/array initially. But I'm not sure it was THAT disk, or some other (I have a bunch of these disks that "don't quite work")... Thanx for all the help everyone. But seeing the thread 'mdadm -D /dev/md3: 1 0 0 0 sync ???' on this list, leads me to believe I'm not THAT far out in wanting some better information on what disk is what... -- Khaddafi Marxist Legion of Doom 767 747 domestic disruption Peking subway nitrate Uzi Kennedy explosion Rule Psix NORAD Honduras [See http://www.aclu.org/echelonwatch/index.html for more about this]
