I did a Debian installation just a couple months ago.

If you're simply trying to combine the DASD into one volume group, simply make them all PVs in the common VG. But I recommend slicing off /boot from the logical volumes. Even where booting through the volume manglement is supposed to work, you're making things more complicated. When something goes wrong, it's harder to figure out and harder to fix. > I believe if I use (software) RAID 0, I can't extend it. So, I'm think > LVM on everything except / and /boot.

My own experience has been with LVM where 'pvcreate' those disks you want to be in the group then 'vgcreate' and 'vgextend' to create the volume group. Later do 'lvcreate' from the one common volume group. Easy! I agree with Mark and Philipp that 60MB is a little small for /boot. I have a habit of sym-linkery to throw /lib/modules under /boot so that kernel modules go on the media with the actual kernel, so my /boot gets larger still. Maybe go for a simple installation just to get the basic op sys laid down, then create your VG afterward. Manually moving things like /usr over to LVM land is ... well ... manual effort, but once it has been done you can then 'apt-get' for whatever other things you need and it all gets installed reliably. -- R; <>< ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
