I found no way, that could do it without hurting the disks too much (I was afraid, that a power failure could destroy the necessary knowledge about the size of the new-config-area; and I didnt know how to do the beginning: it seemed like the first few blocks need a special treatment, because there the new-config-area and the old-config-area overlap)... But Veronica is developing a tool, that can do it in offline mode... With service interruption... But growfs induces a service interruption anyway and it is buggy, if u do not zero the new area... Veronica filed a bug report about this... Nowadays it is common practice to have 2 ot more hosts, that can substitute each other (hot-standby or how they call it today), so that it doesnt matter, if a box is damaged or in maintenance mode or... isnt it?
