You replied to Tom H's message "insserv + apache2 + bind9 = pain" but are not talking about that topic but are instead asking a new question. Please when starting a new topic of discussion just start a new topic and do not jump into the middle of another discussion. This is to your advantage as much as it is to ours since anyone who is ignoring the discussion thread will not see your message. http://lists.debian.org/debian-user/2010/12/thrd4.html#01609 > I would like to transfer these 3 partitions to a new server(also 2 > disks(sda,sdb), also raid1(md0,md1,md2)). > > I used dd to copy the data to the new md devices, but the server > does not boot. > > How can i make bootable my new disks, md device? Please start a new thread with this question. But without saying why your system is not booting it is impossible to know if it is because the bootloader (possibly grub) needs to be installed on the new disks (installed on both new disks) or if because your partitions tables are incorrect for the new disks or if it is another problem. Since your old system was 4.0 you need to say if the new system is also 4.0 or something newer? You would need to use a compatible match. Otherwise the old 4.0 system might not be able to boot a newer system. For example 5.0 has a newer LVM system. Since you are moving from one raid system to a new raid system if I were doing the upgrade I would split the raid. Manually fail and remove one disk from the raid on the old system. Put that disk on the shelf as a backup of the old system. Then install the new disk in the system and add it into the raid system and let the raid sync between the disks. Ensure that grub has been installed onto the new disk. This needs to be done manually since it is not done automatically, at least not in Debian 4.0. Then remove the new disk from the old system and install it in the new system. Boot the new system with the cloned disk. Booting the old image on the new system will probably work but it is possible that there may be some driver issues that will need to be worked through manually. I find those fairly easy to deal with and easier than alternatives and so generally deal with any issues at that point. Then add in the second new disk to the raid on the new system and let the raid sync. You will have a new clone of your old system up and running. Then since you are running Debian 4.0 you should read the release notes and upgrade through each major release to the current stable. Right now that is only Debian 5.0 but soon 6.0 will be released. Do not upgraded from 4 to 6 directly but only through each major release in between. A different alternative but guaranteed working solution would be to use the standard debian-installer and to install a working system on the new drives in the disk partition layout that you desire. Use it to set up raid, lvm, grub, and so forth. Just install the minimum possible system packages to get the system booting. Then copy the data from your old system onto your new system. Bob
