John, I haven't had much luck with YaST and LVM's personally. I have heard that it has problems and that there is a patch for it (but I haven't installed it). I generally do the volume groups and lvm's manually. The doc below from IBM goes through the steps.
Note: I usually do step 2 (the format from Yast because it is faster and I have to activate the dasd anyway) and I haven't run into any problems. http://publib-b.boulder.ibm.com/Redbooks.nsf/RedbookAbstracts/tips0128.h tml?Open After you follow these steps you do have to add the volumes to /etc/fstab and run mkinitrd and zipl to make Linux recognize and activate the volumes at IPL.

I was pretty certain that for the successful LVM that I created that I hadn't done that, but it was some time back, and I might have done just that while following a cookbook. I'm now using YaST to build the LVM volume groups, join the physical volumes to it, and also to create the logical volumes. Are you saying that I also need to then exit yast and run mkinitrd and zipl?

You didn't say what version of linux you are using. John Hello all, I've been fighting an LVM problem and searching through the archives and I stumbled on this from Mark Post from a while back: Re: /tmp as a logical volume Post, Mark K Tue, 21 Jun 2005 21:35:24 -0700 >I'm beginning to have doubts about LVM (version 1 at least) on 64-bit >systems.

This describes my troubles exactly, I create some LVM volume groups (and logical volumes), but they don't survive through an IPL. What I haven't been able to find is any resolution of this problem. What makes it worse, is that I've done it successfully with other volume groups. Mark (or anybody else that shares my woes), have you found any more information about this?
