Creating partition across physical HD's?

[6tr6tr]

I want to make a partition that's bigger than my extra internal hard drive and bigger than the extra free space on my other HD. Basically I have 5 GB free on my master HD and a 10 GB slave HD, and I want to make a 15 GB partition.

1. How would I go about doing this?
2. Are there any issues? limitations?
3. Any OpenSUSE-specific problems with it?

I've read that I can use either LVM or unionfs. What does each choice mean for my filesystem? What i mean is, what will changing it to that do in terms of current usage, risks, etc?

You should begin by opening a terminal and, as root, running "fdisk-l" and posting the results to show what the point of departure is.

You want to google SUSE or openSUSE11.0 and LVM for a howto and familiarisation with the terminology. It's not too hard with SUSEs partitioning tool, but hard to explain. LVM is logical volume management, and just what you want. Good Luck

I won't suggest you to use LVM because its a bit tricky to handle it. None of Partition Manager support LVM and you have to manage it manually through command line only.

I would suggest you to go for ext3 filesystem. Post the output of fdisk -l command here, as suggested by thorkelljarl.

su -
fdisk -l

None of Partition Manager support LVM and you have to manage it manually through command line only.

The SuSE management tool YaST handles LVM with no issues. Google "how to configure lvm yast."

What does each choice mean for my filesystem?

LVM creates a device that the kernel considers just another hard drive (in simplest terms.) The filesystem then goes onto that hard drive. Using LVM has little/no connection to the filesystem.
