Dear list,
I hope this is the right place to ask. If not excuse me and please point me to the right one. I changed my mainboard with processor with 64 bit capability. I used the old hard disks where I installed a Debian 32bit Linux kernel on before, which works. My goal is to “reinstall” Debian with a 64bit Linux kernel. But unfortunately I am getting a problem on the way. Idea: Just reinstall Debian amd64 and tell the Debian-Installer to keep the old /home and /var partition. Problem: I am using a RAID 1 setup with an encrypted partition with LVM volumes on it and I do not get the Debian-Installer to recognize it. Now I will elaborate a bit. You can find a little more information at [1]. # Setup All the following steps were done with the Debian-Installer some time ago. • two hard disks (SATA) /dev/sda and /dev/sdb • Create two partitions sd[ab]0 and sd[ab]1 for boot and data. Each of them were put into a RAID 1 array. • Encrypt md1 with LUKS. • Setup up LVM with logical volumes for /home, /var, /usr, …. • Back then I had to use the work around in [2], but this seems unrelated. # Steps to reinstall Debian with amd64 Linux kernel 1. prepare and boot from USB stick with debian-testing-amd64-businesscard.iso 2. do steps until detect hard disks and than partition hard disk 3. raid devices and LVM volumes are not shown 4. open a shell and do some steps according to [3] # anna-install crypto-modules cryptsetup-udeb # depmod -a # modprobe dm-mod # modprobe aes I think after this step the Raid devices are shown in the partitioning menu of the Debian-Installer. # cryptsetup luksOpen /dev/md1 md1_crypt This succeeds. From here on I do not know what to do. I try # lvdisplay File descriptor 3 left open File descriptor 4 left open File descriptor 5 left open File descriptor 6 left open I did not find anything useful searching the Internet. On [4] it says to use lsof, but this is not available in the Debian-Installer. # mount rootfs on / type rootfs (rw) none on /proc type proc (rw) none on /sys type sysfs (rw) tmpfs on /dev type tmpfs (rw,mode=755) none on /dev/pts type devpts (rw,mode=600) /dev/sdb1 on /hd-media type vfat (ro,fmask=0022,dmask=0022,allow_utime=177777,codepage=cp437,iocharset=utf8) Can you give me a hint and can I provide more information?
