I actually have two questions related to this topic. Let me give a brief
rundown of my system setup, though.
The system is running Red Hat Linux 7.2. I am using Software-RAID for the
root partition (/dev/hda3 and /dev/hdd1 as /dev/md0 RAID-1), and a standard

Intel Server RAID Controller U3-1LA (SRCU31LA)
but I did not find a clear answer,
please, could somebody tell me if I can use linux (Redhat 9 for example)
with this hw RAID card for raid 1 without problems
. Worked OK for me.
Promise PDC20378 SATA RAID 0 - Promise HAS a driver for linux, including

freelance variations of my own) failed to load the controller under a
Redhat 9 install, but the install on 7.3 worked fine.

There'd be no point in having lvm and raid0 on the same drives.
To get mirroring you'd want raid1 or raid5.
You can do this from the installer (in graphical mode). Set up

Any one have any thoughts on whether I can setup LVM and raid0 also? I
am just now starting to dig into the docs on software raid having never
done it before.
