On SL 7? Why? Is there any reason not to use xfs? I've appreciated the
ext filesystems, I've known its original author for decades. (He was
my little brother in my fraternity!) But there's not a compelling
reason to use it in recent SL releases.

What the hell? No partitions? Where did you put the boot loader?

*Stop* putting your software and bundled directories in "/" It's a
violation of the File System Hierarchy, and will cause endless grief.

See above.

See above.

And.... you need to run "parted -l" and "blkid" in order to unfurl the
UUID associations with particular devices. "parted -l" will show you
if the devices are detected. "blkid" wil show you what thte
relationship is between the devices and their UUID's. And as much as I
love, as I love the author of ext based filesystems, I no longer
recommend them for default use, mostly due to their performance with
directories with many, many thousands of files or directories in them.
