What I need, however, would be the possibility, just to replace a disks without reboot. I will umount it first and then suspend/shutdown it som= ehow, so it should disappear from /sys/block. Thus I can safely unplug it and= attach a new disk. If my hardware is unable to recognize the new disk instanta= neously this is not a problem. I may easily activate some scanning process to f= ind and activate the new disk. To accomplish this, IMHO there is no need to= solve all the hotplug problems first. This would be a BIG enhancement for me (and may be others) to keep my d= isk servers up and running. May be some of these steps are already implemen= ted, but then I'm missing some HOWTO. Else I like to hear if his kind of col= d-plug is aimed some day, or if nobody really needs this besides be :-) Dieter. --=20 Dieter St=FCken, con terra GmbH, M=FCnster stueken@conterra.de http://www.conterra.de/ (0)251-7474-501
