Installing from software RAID0?

[Chris Adams]

I tried to install from local hard drives that are configured with
software RAID0, and it didn't work. Should I bother to bugzilla this,
or is this just too far into "don't do that" land?

I doubt that the stripped installer kernel includes RAID support, so this
looks like a “don't do that” deal to me.

/me looks lovingly at the box with the Adaptec SCSI raid card, that's
currently looking for a new home

The installer kernel definately includes RAID support, since you can
install to RAID (and have been able to for years).

Due to space limitations, you can only do hard drive installs from
things that are simple (ie raw hard drives, ext[23] or vfat
filesystems).

I guess you mean space limitations in the first stage installer (since
the second stage does know RAID and can scan them for existing
installations)?

It has been mentioned as a possiblity that floppy boot may go away
because the kernel won't fit (due to ACPI). With a CD boot, the first
stage could be larger (and presumably smarter); any chance of support
for more complex hard drive installs then?

Correct.

Maybe. It's not high on my list of things to consider, though, as hard
drive installs are very uncommon from all the data that I have.

But how am I supposed to upgrade my mirror? :-)

I didn't think about the fact that the second stage hasn't (and
obviously can't have) started at this point. That does make it harder
for little gain.

The NOC is a half mile from the office, and I had to go back down the
street to burn CDs - it was a good thing I'd already copied FC1 to my
workstation, as the mirror OS drive was dead (for anyone trying to use
mirror.hiwaay.net, it'll go down again for a bit shortly - I've got a
different set of drives to use for the OS, so I need to re-install, and
it has a slooow CD-ROM drive).

Perhaps this is in part caused by the inability to do it. I, for one,
would do most of my installs from hard disk if it supported RAID and
LVM.
