All,
I can't get setup-storage to create a partition at the end of a disk
with a specific size. It has to be a range or it doesn't work. The
config below works on a machine with a 250Gb disk. It creates a 70Gb
root partition on /dev/sda1 and a 145 Gb partition on /dev/sda6.
disk_config disk1 bootable:1 align-at:4k
primary / 60G-90G ext3 rw,relatime
logical swap 4G-8G swap rw
logical /export 120G-160G ext3 rw,relatime
But the following config does not work, erroring out during partitioning
with the message that /dev/sda1 is too small.
disk_config disk1 bootable:1 align-at:4k
primary / 60G-90G ext3 rw,relatime
logical swap 4G-8G swap rw
logical /export 140G ext3 rw,relatime
In other words, by itself, given a range, it will create a 145Gb
partition as /dev/sda6. But if I ask it to create a smaller, 140Gb
partition at the end of the disk, it crashes.
I'm trying to use FAI to create a bunch of machines with space for a
distributed network file system (glusterfs). All the "bricks" have to be
the same size. So /dev/sda6 has to be the same size on all machines,
preferably as large as possible. If the disk is 300Gb instead of 250Gb,
I still want a 140Gb partition at the end. And the reason I want it at
the end is that I have to be able to explain the partitioning scheme to
people who are not real knowledgable of linux. For example, I had some
difficulty explaining to someone that they can't do a dual-boot install
unless they see an NTFS partition at the beginning of the disk. It
doesn't matter what is in there but FAI can't preserve a partition that
doesn't exist.
Well, that example doesn't really apply directly in this case because
these are linux-only machines. The point is that I'd really like
thepartitioning to more or less match that of a machine where you did a
regular debian install. I'd like to be able to say "The first primary
partition will be the operating system and the second will contain some
swap space and then space for user files, either /home or /export."
