Perhaps. Or perhaps they're simply playing the "look, we're not a monopoly after all" card.

their biggest competitor still is pirated windows by magnitudes, I know.

So I've given up on the raid over lvm because I don't have enough parts to make it go. But it's still a neat idea.
I've decided instead to try the software raid on my boot drive.
I found a drive the same size as my boot drive and if I understand this right, I make a partition the same size as the boot partition (I don't have /var /usr /boot separated out) and tell mdadm to make a raid array and then tell grub to boot //dev/mda1 or whatever its called.
Apparently setting it up from scratch isn't too hard, but adding raid to an existing setup can be not simple.
You make the array with a space for another device then add it, then sync to it and hope you don't do it in the wrong direction or the blank drive synces over your real drive.
Anybody ever play with this, have any tips?

Generally the way you migrate to RAID is to start with a partially-configured set (declare one drive as broken) and then migrate it, then bring the other drive into the set using raidhotadd.

Try this:

wow that's scary, I have to blow away my old drive's partition table? yeesh.

I didn't say it was safe; I said it was possible. :)

(I did do it once, a long time ago. But I had full tape backups too.)

I just had an odd thought.
Since you can mount a file as a mountpoint, couldn't you do raid from one drive to a file on another drive (assuming there was enough space for the file?)
Wouldn't that be interesting.

well as the saga unfolds....
I found out that the drive I was goign to raid to was .8gig short of the drive I was raiding from.
so I had to shorten the filesystem and partition and move my swap around, but it worked.
As in the machine still boots.
It's low level and geeky, but it's such old technology that it just works.
I'm impressed.

cool. I just copied the partition table over, and it just worked. frikkin cool.

always leave some extra hundret MB's at the end of disks you're raiding...

the replacements you're bying might be a little smaller.

Windoze users don't have that luxury ... their "dynamic disk" layout expects to find metadata at the *end* of the volume.

So I'm up to the part where I fix my grub config
I don't get it and the man pages aren't helping.
There's a command called "root device [hdbias]"
Has something to do with booting debian or something like that.
but I don't get the naming scheme for 'device'
it's like hd(0,0) or hd(0,1)
but it doesn't explain what those numbers mean.
Any ideas?

for that reason I stayed with lilo, as i know how to operate it, and get it through the more complicated cases, in which it is more what one knows from the rest of the linux handling.

LVM and Grub sucks. Grub in general sucks. Damn, that thing just has to fire up the kernel. I've got boxes that won't boot for months. I don't want to make a bootloader diploma before I can handle cerntain stuff.

Grub is indeed over-complicated. I suspect that it's because their primary design tenet is "Linux is the kernel and GNU is the operating system" rather than "just boot the damn thing and don't confuse the user."

I must admit that I too have, on occasion, simply switched back to LILO when I couldn't figure out what grub was doing wrong.

it starts with grub having its verry own syntax for the devices (which is borrowed from the HURD I think, which was its origin afaik) and ends up with the complicated manual doing it all verry theoreticaly and not on linux / *bsd relevant samples.

That's all true. But grub is really powerful and also more flexible than lilo.

So grub: +1 ;-)

One of the many things I'd do if I had unlimited free time would be to create a fork of grub called "Stitch" (which is what grub should have been called in the first place) that differs from the mainline in two ways:

1. It would refer to Linux as an operating system

2. It would have documentation
