Yesterday my system looked like this: 1. /dev/md0 372.61Gb (sda1+missing) 2. /dev/hdb 74.53Gb 3. /dev/sdb 298.09Gb Now with the paycheck, I bought a third SATA disk (400Gb). I new from the start that disk wouldn't fit in my desktopbox, so I also bought a 500W PSU (I had a huge server case without PSU from previously). I was a little impatient, so I added the new disk (physically just dangling outside the box :) to the LVM (as md1+missing). The idea was to re-create sdb as mdX+missing, so I tried pvmove sdb. But instantly received a lot of errors. Now I can't remove it from the VG! I figured this had/might have something to do with the (very) small PSU in the workstation (250W I think it is). My new server is a i386, and I already had a disk with Linux installed for Intel, so that disk was also moved (from another server I don't need any more - it was a Pentium 1 - to slow! :). In with the system disk, in with the LVM disk and started. The system had to be upgraded (from Ubuntu 6.xx to 7.04 - Feisty). Took a couple of hours, and when that was done, I started to get the MD's working. No go... One of the disks didn't even have a partition table!? None of the disks had a MD [info/rootblock/whatever-it-was-called]. I wasn't really scared, I knew I haven't tried to modify the disks. Put everything back into the PPC, and yes, everything works as expected (exept the read errors from sdc/md1). So, long winded explanation of what i've done, any idea about: 1. How do I remove md1/sdc before I get data on it (i have the LVM unmounted for the time being). 2. How do I move a VG/PV/LV from PPC to x86?
