- Full dmraid support. (still disabled by default)
As the changelog says, last night's rawhide build has support for dmraid
during installation. If anybody wants to test this, I'd be really
appreciative ;)
A couple of ground rules/caveats:
1) Right now on a default install /boot doesn't get mounted after
install. In general,
"mount -a" doesn't work just yet, and "fsck -a" probably has
similar
issues. Changing
fstab to point at the device instead of a label will probably fix it
(I haven't tried
that yet ;)
2) It's expecting a partition table on the raid, not a raid on a
partition. AFAIK this
is how all BIOSes actually lay out the metadata, so that should be
normal
3) RAID 0, 1, and (in some cases with some BIOSes) RAID 1+0 only. No
RAID 5 or RAID 6
yet, even if your BIOS does it.
4) You'll probably get a nasty failure if you're doing RAID 1 and your
drives aren't
synced already. (Heinz, we probably should discuss this some)
5) If you move disks that have RAID metadata onto a controller/BIOS that
doesn't support
it, the installer is still going to think they're perfectly good, and
it'll install
grub on them, etc. Don't do that. It won't work.
6) If you've added support already and you do an upgrade, it almost
certainly won't
work. I've got no intention of making this work, either. Sorry.
7) Bug reports should go to
bugzilla.redhat.com . File them against
anaconda; if they
need to be assigned somewhere else, we'll reassign it.
So, without further fanfare:
To enable this, add "dmraid" to the installer boot command line.
