Problem setting up RAID/LVM at installation

[Denis Melnikov]

Hi,

I faced a problem setting up RAID/LVM when installing 6.06.
My server is:
Intel Server Board S5000PAL
Intel SR1500 Chassis
2 Xeon 2.67 GHz CPUs
2 SATA 250 GB HDDs

After creating MD devices of RAID1 I got the following message:

Error informing the kernel about modifications to partition
/dev/md/0p1 -- Invalid argument. This means Linux won't know about
any changes you made to /dev/md/0p1 until you reboot -- so you
shouldn't mount it or use it in any way before rebooting.
ERROR!!!

And:

The kernel was unable to re-read the partition table on /dev/md/0
(Invalid argument). This means Linux won't know anything about the
modifications you made until you reboot. You should reboot your
computer before doing anything with /dev/md/0.

If I reboot nothing changes.

How to create RAID/LVM volumes during installation?

Hopefully,
Denis
