rx4640:disk mirroring in linux AS 3.0

Learn_1 — Wed, 22 Dec 2004 08:18:25 GMT

New to linux.i have installed red hat linux AS 3 on rx4640.The root disk is 70 GB and following partitions has been created on this disk.
/=1024 GB, /boot=100MB, swap=8192MB, /var=5120MB, /home=5120MB, /Opt=3096MB, /usr=6144MB, /temp=2048MB, /oracle=2048MB,/oradata=30720MB

Now i want to mirror these partitions on the 2nd disk having the same.How can i accomplish as i have no prior Linux experince.do we need additional software like Mirrordisk in HP-UX or we can do it from basic linux OS.If someone can forward me the procedure that will help me in doing disk mirroring.
Thanks.

Hi Anwar,

your system does not have a raid controller ? If it has, it's better use hardware raid then software raid.

Just in case your system doesn't have a raid controller, linux has software raid that is called MD, just like HP mirror disk.

You may have all information you need at http://www.ibiblio.org/pub/Linux/docs/HOWTO/other-formats/html/Software-RAID-HOWTO-html.tar.gz

Since you dont seem to have a hardware RAID controller , software RAID will work also. To get this to work though you need to configure this during install process. You'll need to re-install, when you get to the partitioning screen, select manaual and it will give you options for RAID.

You can do it with linux software and you do NOT need reinstall. Yes this software is part of linux install. You need free disk any way :) one more :)

Sorry Dom, but I agree with Ivajlo.

Anwar does not need to reinstall the hole system, he can build the raid device using the actual partions as the primary one.

Please verify the informations on the document that I have posted on my first reply.
