I did once, I had to create a new partition, to put a new service in cluster and replicate its data between the 2 nodes: I resized the /home partition: using fdisk, if I remember, you can move the beginning of a partition, i.e fdisk /dev/sda, then select x for "extra functionality (experts only)" and then b to move beginning of data in a partition. If you don't use LVM, I think that's the only solution

AFAIK You can only do this if you are using LVM and then it is a simple procedure using YAST->Partitioner. Are you shrinking or growing the filesystem ?

Jumping in here....

When resizing partitions must the partitions be UN mounted or is it possible to resize an active fs ie /var without having a data backup?

If you can grow the partition (ie, you have room to extend the partition), then you can grow a ReiserFS filesystem online. I regularly do it, though I use LVM (actually EVMS, but it's using LVM underneath). Generally, I make a small root partition then make the rest of the disk an LVM PV, partitioned into /var, /usr, /home, etc. Those partitions get initially created at a reasonable small size (like, around a gig or so), and I grow them as needed. I've found that to work very well on my home systems - I've even grown filesystems using LVM and Reiser) during video capture to the filesystem being grown, it works quite well. AFAIK, you can't shrink any of the filesystems online. That makes sense, as a program might be trying to write to a block just before the resize operation, but not complete the write until after. So you have to unmount to shrink. Reiser and, IIRC, XFS can grow online - the others (including ext2/3) need unmounted to grow or shrink. --Danny, wondering how he ever got along before LVM :)
