HI all,
I hope someone can give me some insight on this.
I have finally gotten a RAC database up and running on the RedHat AS 2.1 Linux
cluster using OCFS 1.0.9.4.
My XP admin has given dual luns to the drives in which my database sits.
So the question comes up how do I do this? Using software raid?
on the host os'es:
xpinfo -il

/dev/sdp dc 00 07 CL1G 04:1c OPEN-9 00040898
from here:
would I fdisk the devices, then create the raidtab file, then mkraid, then add
them to create the ocfs filesystem, then mount then, then add them to the fstab
and it's done?
Is this even supported? The main reason for all of this is that I see a couple
of conflicting comments on this: don't use raid or lvm on RAC? or yes you
can?
Any insights?
Thanks.
