Hello mate,
..to mirror disks you should use a volume manager as is mentioned above (LVM will do you) -you will need to build logical devices that you can manage - mirror or what ever.
You will need a disk manager get sorted anyway to manage SAN/NAS devices if required- well I dont see any local application moutpoints there.
Your df -h shows me that you having only default linux install/build set up - this does not look like layout of production or test server to me.
Simply you need to re-think the project, partition the disks right, then grab the slices and build the logical devices, and then mirror the devices accross the controllers...
I think you can do the all the low lever work easy in YAST..
Alright. I've asked about the partition layout since it seems quite strange: 3 logical partitions (2 Linux + 1 Swap) inside an Windows extended partition isn't what you usually find in an production environment. A virtual machine might have been better for testing, since you could create snapshots to go back to if a step fails.
I'll try to create a suitable checklist/how-to, but it might take some time. Things like this shouldn't be rushed...

Alright, I think I've got it.
DISCLAIMER:
This procedure is extremely dangerous and should not be applied to any production server without a proven good backup. Neither I nor this site can be held accountable for any data loss you might encounter. Really.
Boot to "Rescue mode" using the installation CD
Replicate the partition layout:
Code:
sfdisk -d /dev/sda | sed -e 's/sda/sdb' | sfdisk /dev/sdb
Change the partition type of /dev/sdb6 to "RAID autodetect"
Code:
echo -e "t\n6\nfd\nw" | fdisk /dev/sdb
Create the array with 1 disk missing (will be added later)

Hi all,
we have an existing system that was configured using just one of the (two) internal disks. I want to mirror the disk using SVM, but have realised there is no free slice for creating the metadb's. Is there a workaround I can use for this?
In the past we have always kept slice 7 free -... (8 Replies)

But during the process instead of attaching submirrors to main mirror
